    Part 1 – Air India 171 Crash: NO-GO Fault & Electric Arc

    Air India crash: How AI 171 had NO-GO faults and still flew; leading to electrical cascade, systems failure

    There is exclusive evidence that Air India 171 reported multiple NO-GO faults 15 minutes before takeoff and was still allowed to fly. Faults that likely resulted in an electric arc on the plane; as a high voltage inverter reached its thermal and dielectric limit, frying the emergency beacon, tail blackbox and knocking out the flight computers and avionics rack – a situation that ultimately could’ve led to engine computer FADEC getting corrupted data and cutting off fuel mid-air.

     

    AI 171 was one of the shortest flights in aviation history. 32 seconds in total. From takeoff to crash.

    A deadly tragedy that claimed the lives of 260. While everyone is familiar with the names of the pilots – Capt Sumeet Sabharwal and First Officer Cliver Kunders. On duty that afternoon of June 12, 2025, were also Air India 171 crew members like Shradha Dhavan, Aparna Mahadik, Saineeta Chakravarty, Nganthoi Sharma Kongbrailatpam, Deepak Pathak, Maithili Patil, Irfan Shaikh, Lamnunthem Singson, Roshni Rajendra Songhare and Manisha Thapa. Their names — representative of the ethnic diversity and cultural richness of India; just as much as the passenger list represented the broader global connect on that fateful day.

    All of them boarded the flight, unaware that AI 171’s systems had likely begun unraveling. Months, days earlier. Deep beneath their feet; inside the aircraft’s labyrinth of wires and power buses.

    The first domino: a failing core network

    On June 9, 2025, maintenance staff logged that the plane’s core network was degrading, as per the Aircraft Accident Investigation Bureau (AAIB) preliminary report. But because Boeing in its operations notes to airlines minimised the damage an inoperative core network could do; maintenance marked the core network as medium-risk (can be fixed in 10 days). And this core network connected about 22 flight critical systems, including FADEC; apart from 28 other more mundane functionalities like the plane’s air conditioning. And later in this article, we’ll show how this was the more important fault and how it connects to all the other failures that followed.

    But prior to core network degradation, the plane was already reporting cabin and cargo related faults in the weeks prior to the crash, as per the AAIB report. Engineers say this points to an intermittent electrical integrity fault affecting the common core cabinets and network interfaces — i.e., the shared platform that hosts cabin and cargo functions and flight critical systems. Now this could be because of electrical fault in the power conditioning module (PCM) — essentially the core cabinet’s internal power supply — which provides regulated electrical power to the aircraft’s network hardware, including the the data traffic router or ARINC 664 Cabinet Switch (ACS) and the the copper-to-fibre signal converter Fibre Optic Translator (FOX).

    And it’s first victim was the common data network (CDN) or core network on June 9 (marked “medium-risk” or CAT C MEL), followed by a fire inerter, a stabilizer motor trim unit and then all three of the plane’s flight control modules by crash day.

    Now let’s take a closer look at the second domino in the chain of failures. On June 10, the plane’s fire inerter or nitrogen generation system (NGS) — which prevents fires in the fuel tanks by depleting oxygen and replacing it with nitrogen — faulted. It was marked as “high risk” (CAT A MEL) and was likely physically inhibited by maintenance.

    In technical terms, the AAIB report notes that the core network got marked a CAT C MEL or “medium-risk,” while the fire inerter got a CAT A MEL or “high-risk.” MELs or minimum equipment lists are the faults with which a plane is allowed to fly, provided it fixes these issues within a specified number of days. And on the day of the crash, Air India had 7 more days to fix the core network issue (till June 19, 2025) and 8 more days to fix the fire inerter issue, as per the AAIB report.

    But the issues kept piling up and then there was a third domino. On June 12, the day of the crash, the stabilizer motor unit and sensors faulted and had to be replaced on the previous morning flight (AI 423 Delhi to Ahmedabad), as per reports.

    D-Day: A jet in fault mode, a cockpit left blind

    The plane’s condition kept deteriorating.

    On June 12, 2025, the day of the crash, 15 minutes before takeoff; at 1.23 PM IST, the aircraft’s ACARS logs started streaming… “BPCU OPS…FCM OPS…CMCF OPS…GPM OPS….HYDIF OPS….”

    “OPS” in Boeing maintenance parlance is “Operations” — shorthand for a detected operational fault. And AI 171 didn’t have one, but multiple operational faults, according to data shared by two independent sources. Malfunctions serious enough to disrupt electrical power stability and data flow across the length and breadth of the 120-tonne carbon-fiber leviathan.

    A NO-GO plane that still flew

    And not just operational faults, but NO-GO items as well. Regulations don’t permit planes to fly with faults as severe as these. So how did AI 171 still fly with no one being the wiser?

    Rewind to three days earlier, on June 9, when the jet’s core network was marked an active fault. This core network once it starts degrading can also impact the function of the systems that report faults — the Aircraft Condition Monitoring Function (ACMF), the Central Maintenance Computing Function (CMCF), and even the pilots’ Electronic Flight Bags (EFBs).

    Boeing’s internal note itself mentions this possibility, saying, “an inoperative core network could impair the ACARS transmission of faults to the cockpit tablets or EFBs.”

    By June 12, the day of the crash, the timing of the failures had turned vicious. The NO-GO faults were occurring at the exact moment the systems responsible for reporting NO-GO faults were themselves failing. The fault-reporting chain went dark.

    So when maintenance signed off on the jet at 12:10 PM IST and when the pilots performed their checks at 1:23 PM IST — the critical faults or NO-GO items simply never appeared.

    So maintenance didn’t know. Pilots didn’t know. But Boeing would’ve known. And so would Air India.

    The ACARS ring that bound them all: Boeing, Air India, SITA, Inmarsat

    As the plane kept sending out warnings — upstream, Boeing and Air India were seeing everything. Like Sauron’s unblinking eye, they were receiving a ring of real-time data from the aircraft’s digital datalink, ACARS.

    That ring formed a tight closed loop: carried by Air India’s sub-contractor SITA, relayed over satellite provider Inmarsat, and delivered to Air India’s operations centre in Gurugram and Boeing’s data monitoring hub in Belleville, Illinois, US.

    At 1:23 PM IST, that ring flashed three sets of NO-GO warnings. ACARS told everyone in the loop that AI 171’s left and right bus power control units (BPCUs), the computers that act as traffic controllers for electrical power, had entered fault mode, unable to keep the left and right 115-volt AC buses in sync. Meaning the airplane’s two main power highways were falling out of phase, a condition that can cause surges, flickers, or even short-circuits across systems.

    The domino effect: Flight computers, processors fall one by one

    Next, all three flight control modules (FCMs) left, right and centre began reporting operational errors. These are the units at the heart of the 787’s fly-by-wire system. They take instructions from the flight computers and translate pilot inputs into precise movements of the stabilizer, ailerons, and spoilers.

    And it doesn’t stop there. Two general processor modules (GPMs) also faulted. These were the 787’s backstage processors; running key software, performing calculations that feed flight management and crew alerting and the nerve-centre for fault detection and reporting.

    Taken together — the out-of-phase power buses, failing flight control modules, and glitching GPMs — AI 171 wasn’t dealing with a single fault but a system-wide degradation. As pilot Rajneesh S puts it, “Aviation outcomes emerge from complex, tightly coupled systems… failures rarely stem from a single decision or individual lapse.”

    And yet, the plane was cleared for takeoff at 1:25:15 PM IST.

    The plane’s pilots — Capt Sumeet Sabharwal and First Officer Clive Kunders, unaware of what was happening inside, guided the plane to the runway. Started roll and lifted-off at 1:38:39 PM IST.

    A surge, an arc, a cascade of collapse

    Now, takeoff is always the most electrically demanding phase of flight — all four power channels, bus control units, and hydraulic pumps draw maximum load as the plane transitions from ground to airborne mode.

    For AI 171, that surge became catastrophic. And core network degradation could’ve caused an electric arc. Now we’ll show you how AI 171’s systems could’ve arced by tracing the failure chain back to what happened on the previous flight of VT-ANB.

    “Gremlins” in VT-ANB; blank screens to blackout

     

    A few hours before the crash, passenger Akash Vatsa — seated aboard the same aircraft VT-ANB on its previous flight (AI 423) from Delhi to Ahmedabad— recorded a short video complaining that the air-conditioning and in-flight entertainment weren’t working, and that even the crew call buttons were dead. Post-crash when he posted the video, viewers mocked him —  calling him a fussy traveller who didn’t understand aircraft systems. But Akash was perhaps unknowingly documenting the first public evidence of a deep electrical failure spreading through VT-ANB’s core.

    Trolled for it; but 787’s Architecture vindicated Akash

    “I was badly trolled, people said I was just doing it to gain publicity; linking the inflight entertainment with air conditioning makes no sense and neither it has anything to do with the crash…I was told a non-working AC and inflight entertainment is very common in Air India,” Akash Vatsa told this reporter.

    But turns out Akash was right. On the 787, the in-flight entertainment, cabin climate control, and crew communication panels are not isolated luxuries; they share both power and data on the aircraft’s core network. The same core network that connects 22 flight critical systems including the pathways to engine computer FADEC.

    So in a scenario that resembles Lewis Caroll’s Alice in Wonderland, engineers say Boeing has created its own electrical hard-to-believe architecture, where the air conditioning, a non-flight critical system, sits ensconced on a network with other flight critical systems.

    And one of the cabin air conditioning’s compressors was sharing the same power source — a high voltage inverter, managed by a common motor system controller (CMSC R2) on the R2 line — as the fire inerter (NGS), marked “high-risk” two days earlier. The same R2 line which on the same flight also saw its right horizontal stabilizer electric motor control unit (EMCU) and stabilizer sensors fail during the descent phase, before landing.

    R2: The Rogue Power Lane

    So when the cabin air conditioning’s cabin air compressor (CAC) is in a bad power domain experiencing power surges and voltage spikes  — it can result in fluctuating air conditioning as Akash and other passengers on Flight 423 (VT-ANB) experienced.

    Below is the power path mapping from the right engine’s variable frequency starter generator (VFSG) to the high-voltage drive used by the fire inerter (NGS) and the right compressor (CAC); and to the power conversion system (PCS) to the right stabilizer motor (EMCU) and sensors.

    Power paths:

    R2 235 V AC main bus → ATRU R2 → ±270 V HVDC → CMSC R2  → NGS/ CAC-R2 / Hyd L EMP

    L2/R2 235 V AC main bus  → PCS (115 V/±130 V/28 V) → right stabilizer EMCU (115 V/±130 V) → right stabilizer sensors (28 V)

    This shows the cluster of failing components — be it the fire inerter (NGS), stabilizer motor (EMCU) or the air-conditioning compressor (CAC) — were all on the R2 line.

    Line 26: Legacy of the “Terrible Teens”

    The problems faced by Air India’s Dreamliner AT-VNB have their origin in the ‘Terrible Teens,’ say experts. In aviation parlance, the “Terrible Teens” refers to a cluster of early-build 787s that came off the assembly line with serious manufacturing defects, requiring heavy rework; becoming notorious inside the industry for persistent quality problems.

    “You see VT ANB (AI 171) was only the twenty sixth 787 built (line #26) , and back then the 787 factory in Everett, Washington was known to be having a lot of manufacturing quality issues,” Ed Pierson told the reporter.

    He said one area of particular concern was the aircraft’s electrical wiring interconnect system (EWIS). “Over the years, we’ve seen some very dangerous EWIS practices across multiple Boeing programs — not just the 737, but the 787 as well. Fatigued employees, skipped installation plans, poor electrical bonding and grounding, improperly installed wire bundles, unqualified staff performing electrical work, rushed functional systems testing, and the removal of long-standing quality inspections— all of this can create latent defects in a variety of aircraft systems that can be extremely difficult to troubleshoot,” said Pierson. He adds, “These flaws often produce those frustrating ‘No Fault Found’ or ‘Could Not Duplicate’ maintenance reports. In the military, we used to call them gremlins.”

    Was Fire inerter a victim to power transients?

    And if we rewind a little here, we can see how the first gremlin may have been the fire inerter. Remember how two days before the crash on June 10, maintenance engineers had marked the fire inerter (NGS) a high-risk fault?

    Well this fire inerter (NGS) is designed to prevent explosions by flooding the 787’s fuel tanks with nitrogen-enriched air and depleting its flammable vapour i.e. “live” oxygen. To feed that flow, the NGS uses a compressor and a high-voltage inverter, controlled by a common motor system controller (CMSC R2). And this high-voltage power line (CMSC R2 ±270 V) also feeds a cabin air compressor (CAC) and hydraulic electric motor pump (L) in the aft power distribution bay. The same compressor (CAC) whose faults were visible to the passengers above when the air-conditioning fluctuated on the previous flight (AI 423).

    Where cooling failure becomes combustion risk

    Now comes the most inconspicuous but dark horse fault of all on the crash flight. In the tail section there is an aft zonal dryer, a small unit that removes moisture from the ventilation air around the fire inerter (NGS), compressor and its cooling ducts.

    On AI 171, this started showing abnormal readings at 1.23 PM IST, 15 minutes before takeoff, as per data from two independent sources.

    This would lead to moisture building in the aft bay; a sharp rise in humidity as the dryer isn’t removing water vapor. Condensation risk increases as droplets can form on wiring, high voltage inverters, raising the risk of short circuits or even an arc. And the cooling efficiency also drops as the moisture load would make the environmental control system (ECS) work harder and reduce heat removal margin from electronics.

    Water turns fire: How aft-bay moisture caused electrical failure

    Given what Ed Pierson and other whistleblowers have said about Boeing’s practises and improper bonding of the electric wiring interconnected system (EWIS) — a latent EWIS defect could also play in.

    So 15 minutes before takeoff and 2 minutes before taxi clearance, it’s possible the AI 171’s aft high voltage system was in an unstable state. With cooling faltering, heat building up, moisture settling in and the twin power buses (BPCUs) slipping out of phase, the airplane’s systems were likely reaching their tipping point.

    Zonal dryer turns tail into heat zone: The first ripple in AI 171’s core

    And then they seemed to have tipped over. As per data from the sources the “aft zonal dryer” anomaly seen at 1:23 PM IST likely escalated into a full-blown failure after takeoff at 13:38:39 IST.

    Flight logs accessed show an ACARS message (167280002) shows that there was a failure on the aft zonal dryer’s control feedback path in the integrated cooling system (ICS) that connects to the aircraft’s core data network. Or in other words the moisture-removal or dehumidification loop in the tail section likely failed.

    High voltage inverter drives turns metal-melting arc source

    When the aft zonal dryer fails, humidity rises and the insulation margin inside the high-voltage inverter, controlled by CMSC R2, drops sharply. If the BPCUs are also faulting, power quality can swing violently and protection may not isolate the inverter when it should. At the same time, a degraded core network can delay or corrupt trip commands, keeping the inverter energised even as its insulation environment is collapsing. And loads such as cabin air compressors for the air conditioning would likely put more stress on the inverter precisely as the insulation environment was most vulnerable.

    Under these stacked conditions, the high voltage inverter would possibly become increasingly vulnerable. As the heat builds up it is likely the inverter reached its thermal and dielectric threshold limits — meaning its cooling and insulation could no longer contain the voltage.

    “When that happens the inverter will discharge through nearby wiring harnesses a sustained electrical arc, a plasma-level short that can melt metal and vaporize insulation,” said a flight engineer, who did not want to be named.

    The surge that reached the Dreamliner’s nerve center

    So if a high voltage inverter arced; then this burst of energy would’ve sent transients —  sharp voltage spikes — surging back through the airplane’s 28-volt and 115-volt power buses, rippling through the core network, the data-power spine that links almost every system on the 787.

    And it looks like it did — because ACARS fault codes (252490002, 167280002) indicate that this arc likely hit the forward electronics and electrical bay. And they were probably hit harder than they normally would have because of the existing faults before takeoff.

    When two power lines fail, two others carry the plane — until they don’t

    At 1.23 PM IST, 15 minutes before takeoff, when the system began throwing up processor (GPM), fault monitoring system (CMCF), power controller (BPCU faults) this would have impacted the power routing of flight critical systems.

    The plane has two engine generators (left and right VFSGs) supplying power to four lines — L1, L2, R1 and R2. Given the nature of the faults, the system would have first decided to route flight critical components away from L1 as this line had multiple faults (GPM Left 1 + CMCF Left + BPCU Left) and would have been identified as an unclean source of energy. The next line that would’ve been marked as suspect would have been R1 as this too had faults (GPM Right 4 + BPCU Right). Leaving L2 and R2 as the lines that were probably being used most by the flight critical components on the plane. If L2 or R2 were the components’ secondary electrical path.

    The arc that hit the heart: the R2 power-line arc

    But these two lines L2 and R2 were also seeing components faulting. At 1.23 PM, 15 minutes before takeoff, the right hydraulic electric motor‑driven pump on the L2 line was faulting (HYDIF RIGHT OPS). And as we discussed earlier the R2 line had already seen the fire-inerter (NGS), stabilizer motor (EMCU) and air conditioning compressor (CAC) failing.

    So given more than normal components might be mapped on to the L2 and R2 lines – an arc on the R2 line could’ve had far more impact than normal as it hit the forward and aft avionics bay.

    Once forward and tail avionics are hit they can begin spitting corrupted data and degraded voltage states. And those kinds of faults can bleed directly into FADEC logic. If FADEC sees invalid or contradictory control signals — it can try to “protect the engine” by limiting thrust during takeoff roll. And more dangerously — if this happens once airborne — FADEC could decide to shut the engines.

    When power source for cooling systems starts the fire

    The irony could not be more brutal. If the above interpretation is true the power sources for systems designed for cooling and to prevent fires — appears to have ignited the airplane’s electrical core instead. The high voltage inverter of the fire inerter and airconditioning likely arced to structure, burning through the aft equipment frame, cooking the wiring of the emergency distress beacon (ACARS code 252490002), crippling the auxiliary power unit (APU), charring the tail blackbox (aft EAFR), cutting the anti-collision strobe lights and starting a blackout that killed half the aircraft’s avionics and its lines to the engines.

    The scenario of the plane’s ELT and EAFR getting knocked out by an electric arc is consistent with the AAIB report, which says, “the Emergency Locator Transmitter (ELT) was not activated during this event…..the (aft) EAFR had impact and thermal damages to the housing. The wires were protruding from the housing and the connectors were burnt.”

    Boeing Papers Admit: Single Fault Can Trigger 787 Cascade

    This possibility of an arc on the R2 line cascading across multiple systems is admitted by Boeing in an internal document, where it states, “The loss of a single component within the common core system (CCS) can affect multiple systems.” And on AI 171, the component failing  – if it can be called that – was the core network. The host of the central computers, CCS, flight control computers and the command arm of the power controllers or BPCUs.

    Boeing itself states that the 787’s architecture “differs from the traditional aircraft system, where each individual system requires its own dedicated communications route…the 787 architecture reduces the amount of wiring, hardware and overall weight of the airplane…and in this architecture, individual component failures can impact multiple systems.

    Neither Boeing, Air India, DGCA India, AAIB, or other regulatory agencies like EASA have responded to request for comment.

    What Boeing didn’t design for: emergency power failing before engines

    And then comes an event that could star in Ripley’s “Believe it or Not” as this plane seems to have had its emergency power fail before the engines did. An ACARS fault code (163840003) could indicate the APU’s control unit was also hit in the power transient.

    But even if one didn’t go by the fault code but just by logic and Boeing literature, then again the emergency power or auxiliary power unit (APU) will not function until it can clearly determine a stable high-voltage source. And on AI 171, the APU likely didn’t have that.

    The power gatekeeping BPCUs had started faulting and the core network was degraded —  meaning commands to isolate a failing unit would get delayed or corrupted. So in this deck of cards, when one of the high voltage inverters arcs, with no clean high-voltage source, the 787 can auto-inhibit APU start. Because Boeing’s design philosophy was that loading a heavy consumer like the APU starter motor onto an unverified rail risks accelerating the collapse. What it wasn’t budgeting for was an electric failure that possibly first crippled the emergency power, before it triggered dual engine failure, say engineers.

    The APU That ‘Looked Fine’

    But going by the AAIB report, you wouldn’t think anything was amiss with the APU. As AAIB report states, “ÄPU was recovered intact…APU inlet door began opening at 08:08:54 UTC.”

    Engineers say APU inlet door opening was probably a result of manual action by Captain Sumeet; and not system-driven as the 787 is unlikely to auto-start in the middle of a surge on the high-voltage drive line.

    Faults treated in isolation hid electrical failure behind 787 crash

    So going back in time, the fire inerter (NGS) being identified as an active fault on June 10 seems to have been the alarm siren for a deeper electrical problem on the plane. In hindsight the engineers say the crash itself may have never had happened had the NGS and stabilizer motor problem not been seen in isolation as Boeing’s fault isolation manual (FIM) asked engineers to do.

    If Boeing and the airline had given engineers more authority, leeway and time when it came to dealing with faults, engineers say they are certain that the root cause would have been identified. That it was likely a bad power domain that had impacted the fire inerter, stabilizer motor unit and finally the high voltage inverter — triggering an arc that likely hit the forward avionics rack and inputs to engine computer FADEC — possibly resulting in engine shutdown and ultimately the plane crash.

     

    And the end of the hopes and dreams of scores of people; people like Shradha Dhavan, Aparna Mahadik, Saineeta Chakravarty, Nganthoi Sharma Kongbrailatpam, Deepak Pathak, Maithili Patil, Irfan Shaikh, Lamnunthem Singson, Roshni Rajendra Songhare and Manisha Thapa — Air India’s crew who’d probably participated in safety demonstrations a minute or two earlier.

    (Disclaimer: The AAIB has not yet released its final report on the AI-171 crash. All the technical scenarios presented here are based on preliminary information, evidence submitted in India’s Parliament and Supreme Court and remain hypotheses. Also the ACARS codes mentioned in the story are not a direct map to maintenance faults as listed in Boeing’s Fault Isolation Manual; as maintenance faults are 7-8 digit strings. The 9-digit ACARS string is only partially recognisable to engineers as its proprietary code of Boeing.  For this story on conditions of anonymity we have spoken to pilots and flight engineers in India, Europe and US; and for details on actuators, sensors, structural engineering and logic paths to IT, mechanical, electrical and electronic engineers from India, working for firms that are Boeing sub contractors.)

     

     

     

  • IndiGo Airlines’ Operational Crisis and Its Consequences for Indian Aviation

    IndiGo Airlines’ Operational Crisis and Its Consequences for Indian Aviation

    Quick Take
    IndiGo Airlines, India’s largest domestic carrier, hit a massive snag in early December 2025 with a large number of cancelled and delayed flights. The main reason was that Indigo was not ready for the strict new safety rules on how long pilots can fly, known as Flight Duty Time Limitation (FDTL), set by the aviation watchdog, the DGCA. This blunder was compounded by the fact that the airline also had 50 to 70 planes sitting idle due to technical glitches involving Pratt & Whitney engines.

    The fallout was nasty: big financial hits evidenced by a decline in stock valuation and substantial refund expenditures, and a seriously bruised reputation with IndiGo’s On-Time Performance (OTP) tanking to an abysmal 19.7%, which typically exceeded 80% before the crisis. It also left a whole lot of unhappy passengers stranded across major airports, particularly during the high-demand winter period. Competitors like Air India and Akasa Air cashed in with higher prices and snatched up market share. The IndiGo crisis also placed considerable strain on the country’s overall airport infrastructure.

    This whole chaos was a wake-up call, demonstrating that running a “bare-bones crew” model just doesn’t fly in the face of non-negotiable safety rules mandated by the regulators or, as in this case, the judiciary. It also underscored the role of the regulatory and judicial authorities in fundamentally shaping the operational and financial strategies of both private and public airline entities.

    Why the Wheels Came Off?

     The disaster was the result of new safety rules colliding with a risky strategy, particularly that of IndiGo Airlines. The new rules require the DGCA to implement the revised FDTL norms, which were intended to mitigate pilot fatigue and enhance flight safety standards.

    Table 1.

    Cause Category Specific Cause/Factor Description
    Regulatory Change New FDTL Norms The DGCA mandate necessitated an increase in the weekly pilot rest period from 36 to 48 hours, an expansion of the definition of night hours, and a severe limitation on the maximum number of night landings (from six to two per roster cycle).
    Operational Strategy Under-Rostering/Crew Shortage IndiGo historically operated with a paradigm focused on high aircraft utilisation. Its standard crew buffer (estimated at approximately 4%) became effectively zero under the new regulatory framework. Pilot associations contend that this shortfall resulted from management’s “lean manpower strategy” and hiring moratoria, despite a two-year period for preparatory action.
    Technical Factors Grounded Aircraft The airline’s capacity for operational flexibility was severely constrained by the grounding of an estimated 50–70 Airbus A320neo family aircraft. This was principally attributable to inspection requirements and component shortages related to Pratt & Whitney engines.
    Outside Interference Winter/Airport Traffic Bad winter weather, minor technical issues, and already overcrowded major airports led to crew-related delays that rippled across their entire flight network, resulting in a substantial number of daily cancellations.

     Consequences

     The Damage and the Industry Reaction

    The consequences of the IndiGo crisis were immediate and painful, which spread across the entire aviation industry.

    • Money and Image: The stock price for the parent company, InterGlobe Aviation, dropped due to higher costs and refund payments. Its image as the reliable, on-time airline was severely damaged. The company, previously lauded for its operational punctuality, faced widespread public indignation and negative media coverage over delays, inadequate communication, and poor passenger support, thereby eroding its brand equity. The widespread chaos also raised doubts among investors and passengers about the overall stability and planning skills of the Indian airline industry.
    • Operations and Oversight:  The disruptions instigated a massive cascading failure across the network, resulting in delayed crew rotations, aircraft being immobile at various airports, and a generalised loss of effective operational control.
    • Regulatory: The DGCA stepped in with a formal investigation, putting IndiGo under the microscope.

    The wider effect on the Indian aviation market was concerning as well.

    Impact on Other Major Airlines in India
    Given IndiGo’s dominant market position (exceeding 60% of the domestic market), its operational disruptions invariably affected the entire Indian aviation ecosystem, albeit with varying impacts.

    IndiGo Versus Competitors
    The differential impact of the FDTL norms as described in Table -2 highlights the varying operational strategies employed by major Indian carriers.

    Table 2

    Carrier Operational Strategy FDTL Impact & On-Time Performance (OTP)
    IndiGo The Low-Cost Carrier (LCC) model focuses on high fleet utilisation, fast turnarounds, and aggressive scheduling, particularly for late-night flights. Hit the hardest due to insufficient crew planning. OTP dropped to lows of 19.7%, significantly impacting reputation and revenue.
    Air India/Vistara (Tata Group) More diversified/Full-Service models; typically maintain larger pilot buffers and fewer highly aggressive night schedules compared to IndiGo’s LCC core. While the group also lobbied against the rules, they were largely unaffected by the immediate operational meltdown. Their OTP remained relatively stable (e.g., 66.8%–67.2% during the crisis).
    Akasa Air Newer, agile LCC. Benefited from learning from older airlines’ mistakes and potentially scaling up its crew faster. Maintained strong operational stability during the crisis, reporting OTPs in the range of 67.5%–73.2%.
    SpiceJet Legacy LCC, often facing its own financial/operational challenges. While not immune to industry pressures, their OTP (e.g., 68.7%–82.5% range) remained significantly higher than IndiGo’s during the disruption period.

     

    Market and Systemic Effects of IndiGo’s Crisis

     Table 3

    Airline/Sector Impact Description Market Effect
    Competitors (e.g., Air India, Vistara, Akasa Air) Temporary Market Share Gain Passengers displaced by IndiGo’s cancellations transitioned to competing carriers, leading to a short-term increase in passenger volumes for rivals.
    Competitors (Revenue) Surge Pricing and Higher Yields The sudden reduction in available network capacity from IndiGo’s cancellations allowed other airlines to implement substantial surge pricing, yielding significantly higher ticket revenue on specific routes (e.g., Delhi-Bengaluru).
    Airport Operations Systemic Strain The disorder at major aviation hubs (Delhi, Pune, Mumbai, Bengaluru) was not restricted to IndiGo. Grounded IndiGo aircraft occupying parking positions impeded the movement and punctuality of all other airlines. Furthermore, passenger unrest at boarding gates disrupted the boarding processes for other flights.
    Broader Market Negative Sector Sentiment Although competitors realised short-term financial gains, the extensive chaos undermined overall investor and passenger confidence regarding the stability and planning efficiency of the Indian aviation sector.

     

    The IndiGo crisis vividly demonstrated the fragility of a hyper-efficient, operationally lean business model when confronted by abrupt, non-negotiable regulatory shifts, particularly ordained by those prioritising aviation safety, such as the FDTL norms. While competitors accrued temporary benefits from increased fares and passenger diversion, the underlying issue underscored the necessity for long-term human resource planning across the entire industry.

    Besides, ultimately, the Indian aviation sector functions under the guidelines and standards, including critical safety mandates, that the regulators like DGCA and AAI enforce, while economic regulators determine market structure and operational costs. Policies, whether judicial in origin (e.g., the High Court’s directive leading to new FDTL) or governmental (e.g., AERA tariffs and privatisation initiatives), emphasise the parameters that all airlines, public or private, must navigate to ensure safety (for the customers), viability and stability (for the industry).

    The Fix: Getting Back on Track
    Solving these critical issues needs both a quick patch-up and a fundamentally sound long-term strategy.

    The central challenge involves addressing immediate resource constraints, specifically, the deficit of pilots due to the new FDTL norms and the incapacitation of 50–70 aircraft due to issues with Pratt & Whitney engines, while simultaneously pursuing long-term, systematic solutions to ensure sustainable expansion of the aviation sector.

    Short-Term Fixes

    Cut flights: IndiGo must actively reduce its flight schedule with “calibrated adjustments” to match the limited FDTL-compliant crew it actually has. The airlines should focus on reducing nighttime flights to comply with the new norms. The DGCA must formally approve the diminished schedule and enforce a strict timeline for restoration, ensuring the rebalancing measure is authentic and not a transient manoeuvre.

    Temporary FDTL Exemption: On 5 December 2025, the DGCA provided IndiGo with a one-time exemption from new pilot night-duty rules and revoked a regulation that prohibited airlines from classifying pilot leave as weekly rest. However, this exemption has generated widespread apprehension, most notably from the International Federation of Air Line Pilots’ Associations (IFALPA), which states that crew fatigue “clearly affects safety.”

    Fast Leasing:  IndiGo need to quickly hire temporary aircraft and foreign crew through wet and damp leasing arrangements to instantly inject pilots and capacity. The DGCA must streamline the security clearance and licensing endorsement procedures for wet-leased crew and aircraft to facilitate rapid deployment

    Fix the Planes: IndiGo and other affected carriers must engage in intensified collaboration with Pratt & Whitney (P&W) to expedite the delivery of spare engines and components. This necessitates aggressive follow-up, including, if necessary, diplomatic pressure on P&W’s parent company (RTX Corporation) to prioritise Indian carriers, given the magnitude of the crisis.

    Maintenance, Repair, and Overhaul (MRO) Push: Engine maintenance must be expedited through the utilisation of P&W’s Customer Training Centre and the India Engineering Centre (IEC) in Bengaluru. The government should provide incentives (such as the reduced GST on MRO components) to encourage domestic and international MRO centres to rapidly expand their capacity for quick engine turnarounds

    Long-Term Strategy
    To ensure the industry’s future growth, particularly in demand, does not precipitate a recurrence of systemic failure, the industry requires strategic, large-scale investment in both human capital and physical infrastructure.

    Invest in People:
    All airlines must set aside resources for a mandatory 15-20% crew buffer, as is the rule now. This means saying goodbye to the “lean manpower” idea and building a required crew reserve pool to ensure compliance with the new rules and also absorb future regulatory adjustments, training demands, and natural attrition rates.

    Better Training: The Indian Ministry of Civil Aviation (MoCA) needs to incentivise the rapid expansion of local flying schools and flight simulators to keep up with the massive number of new planes ordered by various airlines and reduce the reliance on expensive foreign training.

    Upgrade Infrastructure: The government needs to speed up the construction of secondary airports (such as Jewar and Navi Mumbai) to take the pressure off the fully packed primary hubs. The Airports Authority of India (AAI) must invest in modern Air Traffic Management (ATM) systems to allow more planes in the airspace and reduce delays caused by weather.

    Stronger Supply Chain: Airlines should think about mixing their fleets (e.g., using both Airbus and Boeing jets). The “Make in India” scheme needs to aggressively focus on building local MRO capacity for new-generation engines to reduce reliance on fragile global supply chains for crucial maintenance.

    To sum up, IndiGo needs to honestly cut its schedule in the short term, with the regulators keeping a close watch on any temporary waivers. But for lasting stability, the entire Indian aviation sector must make coordinated, major investments in its human capital and physical assets to comply with the necessary regulatory and judicial mandates.  The primary focus for the entire industry is safety and passenger comfort, which can’t be overemphasised.

  • The Catastrophe of Air India 171: An Inquiry Meant to Improve Safety — and an AAIB Report That Doesn’t

    The Catastrophe of Air India 171: An Inquiry Meant to Improve Safety — and an AAIB Report That Doesn’t

    The crash of Boeing 787 Dreamliner of Air India 171 flight (Ahmedabad to London), minutes after takeoff, led to the death of all onboard, save for the miraculous escape of one passenger. Over the last two decades, a series of accidents and failures has put a big question mark on Boeing’s work ethic and the reliability and safety of its planes. The Expose on the Boeing 737 Max fiasco have effectively driven Boeing’s reputation into the mud. The accident investigation into the AI-171 has raised a maelstrom of doubts, questions, and protests over the investigation’s reliability, as the preliminary report indirectly insinuated possible pilot error. This resembles Boeing’s influence in earlier investigations of accidents involving the 737 Max.

    Rachel Chitra is an investigative journalist who has worked at outlets such as Reuters, Forbes, and The Times of India, and was a Reuters Fellow (2021). Her reporting has uncovered issues with PM Cares Fund, CAA, migrant deaths during the COVID-19 lockdown, among other issues. Her investigative work has been cited by media outlets such as the BBC and GIJN, the Opposition in Parliament, and submitted as evidence before the Supreme Court. She has recently published a four-part investigative series for The Federal and an in-depth analysis for Frontline on the Air India 171 crash and its safety implications. This article raises very pertinent observations on India’s aviation safety.

    In the 15-page preliminary report, AAIB refers to fuel, fuel quantity, fuel control switches, fuel cut-off, or fuel-related behaviour at least 19 times, repeatedly steering interpretation toward a fuel-switch narrative.

     

    Nearly everyone on board Air India flight AI-171 died within seconds after take-off.

    In 32 seconds – one of the shortest flights in history.

    AI 171’s crew included Roshni Songhare, Saineeta Chakravarty, Shradha Dhavan, Aparna Mahadik, Maithili Patil, Manisha Thapa, Nganthoi Kongbrailatpam Sharma, Lamnunthem Singson, along with Deepak Pathak and Irfan Shaikh — men and women who had trained for years for a life in aviation. Many at the very beginning of their careers. Their goals, dreams and ambition – gone in 32 seconds like it was for the passengers on board – the elderly, infants, couples, entire families.

    The deadliest aviation disaster in India’s history, and the first fatal crash of a Boeing 787 Dreamliner.

    When tragedies of this scale occur, aviation investigations exist for one reason: to establish what failed, so it cannot happen again. Not to assign blame. Not to protect reputations. But to interrogate systems with enough honesty that future lives are spared.

    Yet six months after the crash, the official preliminary report into AI-171 raises a more disturbing possibility: that the investigation itself may be structured to prevent the most dangerous safety question from ever being asked.

    That question is this: Did the aircraft’s engine computer FADEC command a fuel cutoff seconds after liftoff — because flight computers went to “on ground” logic in the air?

    That question begins with a single line buried in the report’s take-off sequence.

    At 08:08:39 UTC, Air India flight AI-171 left the ground.

    The Aircraft Accident Investigation Bureau (AAIB) states this explicitly in its preliminary report: “The aircraft air/ground sensors transitioned to air mode, consistent with liftoff at 08:08:39 UTC.”

    That sentence is the most important technical fact in the entire document.
    And it is never returned to again.

    Every subsequent line of the AAIB report is structured to ensure the reader does not ask the only question that matters after 08:08:39 UTC:

    Did the aircraft remain in “air mode” digitally after liftoff — or did it revert to “on-ground” logic while physically airborne?

    The AAIB report does not answer this question. It does not even acknowledge that it exists.

    And this matters because the engine computer — FADEC — is permitted to command a hard fuel cutoff only under two circumstances: engine overspeed protection, or Thrust Control Malfunction Accommodation (TCMA) — a protection mode that gets triggered only if the aircraft’s systems believe it is on the ground.

    TCMA is activated only when four conditions are simultaneously met: the aircraft is classified as on ground, airspeed is below 200 knots, altitude is below 17,500 feet, and commanded thrust (selected N1) exceeds a defined threshold.

    AI-171 met every one of those conditions seconds after liftoff — if, as the evidence suggests, its flight-control logic briefly reverted from air mode to on-ground mode while the aircraft was physically airborne. And if AI 171 did meet TCMA conditions, it becomes highly likely that this plane had a FADEC-commanded fuel cutoff.

    So now let’s go into how the AAIB’s narrative is hard at work to steer us away from the possibility of such an occurrence by looking first at the take-off sequence.

    How the real sequence begins — before the narrative takes over

    The AAIB’s own timeline establishes a clean, uneventful take-off sequence:

    • 08:08:33 UTC — V1 reached at 153 knots IAS
    • 08:08:35 UTC — Vr reached at 155 knots IAS
    • 08:08:39 UTC — air/ground sensors transition to air mode (liftoff)

    Up to this point, there is no anomaly. The aircraft is airborne, committed to flight, and operating within normal take-off parameters.

    Everything that follows occurs after the aircraft is already in the air.

    “Maximum recorded airspeed”: the first linguistic sleight of hand

    The AAIB then writes:

    “The aircraft achieved the maximum recorded airspeed of 180 knots IAS at about 08:08:42 UTC…”

    This line does two things simultaneously:

    1. It introduces the phrase “maximum recorded”, not “maximum achieved.”
    2. It uses IAS, a pilot-facing parameter, not the true air speed (TAS) or calibrated airspeed (CAS) — which is the calculated/synthesised value used by FADEC to command thrust with fuel control.

    In an aircraft still at take-off thrust, basic physics dictates that acceleration cannot stop instantaneously. As Newton’s First Law of Motion states: “An object will remain at rest or in uniform motion unless acted upon by an external force.”

    At the point in time, the AAIB identifies as the aircraft’s “maximum recorded airspeed” — 180 knots IAS at about 08:08:42 UTC — no such external braking force is identified. Even if fuel flow were interrupted at that instant, the aircraft’s mass and momentum would require it to continue accelerating briefly, not plateau abruptly.

    A sudden halt at a “maximum recorded” value, therefore, is not evidence of the plane’s true “top airspeed.” It is more consistent with interrupted recording, logic disturbance, or power loss due to an electrical failure — precisely the kind of upstream event the AAIB does not interrogate. Instead, the report immediately pivots away.

    The pivot: fuel becomes the “event”

    The very next sentence reads:

    “…and immediately thereafter, the Engine 1 and Engine 2 fuel cutoff switches transitioned from RUN to CUTOFF position one after another with a time gap of 01 sec.”

    From this moment on, the report’s framing is locked.

    Fuel is now the main actor.

    In the 15-page preliminary report, AAIB refers to fuel, fuel quantity, fuel control switches, fuel cut-off, or fuel-related behaviour at least 19 times, repeatedly steering interpretation toward a fuel-switch narrative.

    This matters because fuel is downstream in a modern fly-by-wire aircraft. Fuel flow is not an independent cause; it is something commanded — by pilots, by automation, or by protection logic.

    And the report never interrogates the command path that resulted in fuel cutoff.

    Was it the fuel getting cut off? Or the autothrottle?

    Immediately after describing the fuel cutoff switches, the AAIB inserts a single paraphrased cockpit line:

    “In the cockpit voice recording, one of the pilots is heard asking the other why did he cut off. The other pilot responded that he did not do so.”

    The transcript does not say fuel.
    It does not say switch.
    It does not say engine.

    “Cutoff” is an effect, not a system.

    But by placing this sentence directly beneath the fuel-switch paragraph — after saturating the report with fuel references — the AAIB ensures that the reader supplies the missing noun.

    And readers think there was a fuel switch being cut off – when, for all we know, First Officer Clive Kunders could have been referring to the autothrottle, given the pre-existing electrical failures on the flight. And his question could’ve very well have been “Why did it cut off? – the “it” was lost in the blizzard of chimes and warnings from EICAS.

    So when the AAIB report gives us a paraphrased sentence about the cockpit conversation without context and data, it becomes damning. And as a petition in the Supreme Court puts it – “it’s narrative framing, not real evidence.”

    A Flight-Control Failure the AAIB Leaves Out — By Design

    Independent reporting and maintenance records show that AI-171 had already experienced a flight-critical failure two hours before the crash — one that directly involves the electrical architecture that the AAIB avoids examining.

    What the AAIB report also ensures is that the reader does not know that this aircraft did not enter take-off roll in a clean, stable flight-control state.

    Independent reporting and maintenance records show that AI-171 had already experienced a flight-critical failure two hours before the crash — one that directly involves the electrical architecture that the AAIB avoids examining.

    On the aircraft’s previous flight, AI 423 Delhi to Ahmedabad, AAIB report says, “the crew logged a Pilot Defect Report (PDR) for the status message “STAB POS XDCR” — a failure involving the stabilizer position transducer…troubleshooting was carried out “as per the FIM” by Air India’s on-duty Aircraft Maintenance Engineer, and the aircraft was released back to service at 06:40 UTC (12.10 PM IST).”

    What the report does not say — but what maintenance logs make clear — is that it wasn’t just a problem with the transducer or sensor – but with the entire right horizontal stabilizer electric motor control unit (EMCU). The entire unit failed and had to be replaced along with its wiring and sensors.

    And as per the maintenance log, this condition was detected by all three Flight Control Modules (FCMs). In other words, a flight-critical component under FCM command failed, was troubleshot, and the aircraft was returned to service.

    Then comes more crucial evidence, where again AAIB preserves a blanket silence.

    Precisely 15 minutes before take-off at 1:23 PM IST (7:53 UTC), all three Flight Control Modules (FCMs) – left, right and centre – started reporting faults, as per data from the plane’s satellite transmissions or ACARS data.

    That context is essential because this evidence has been presented to the Supreme Court. This aspect is discussed in an interview with Barkha Dutt on Mojo Story, where the sequence of pre-existing electrical and flight-control faults was publicly laid out. This was also summarised on LinkedIn.

    And this is where the Indian media should ask itself why aviation-safety evidence is being left to circulate on LinkedIn? What are the forces at play that prevent the publication of this evidence as front-page news?

    Why do we celebrate Netflix’s Downfall: The Case Against Boeing without imbibing its most uncomfortable lesson? That the reckoning happened only because Ethiopia bypassed Washington and took the black boxes to Europe, straight to EASA and Airbus. Today, the AAIB has done the exact opposite — flying to Washington in December to sit with the NTSB and Boeing for spectral analysis of the cockpit audio.

    If Ethiopia had done what India did, it’s highly doubtful there would be any Netflix film today about Boeing. And it’s also highly doubtful that Indian pilot Bhavye Suneja and his Ethiopian counterparts, Yared Getachew and Ahmednur Mohammed Omar would’ve been vindicated.

    Because in crashes, it’s not just evidence that matters – but the location. Where is the evidence getting interpreted? As this can be the deciding factor in whether the truth emerges at all.

    In today’s vacuum of reporting on the Air India crash, manufacturers and operators are winning by default — not because the evidence is weak, but because it is not being examined or amplified.

    And you can see this broader failure of scrutiny play out in the AAIB’s own preliminary report — not through what is stated, but through what is selectively reported.

    How the AAIB Curates Evidence to Signal ‘Nothing Went Wrong’

    The most revealing part of the AAIB report is not what it says, but when it chooses to quote digital data and when it avoids it.

    When digital data supports “normal flight,” AAIB quotes EAFR

    • Flap handle: “Firmly seated in the 5-degree flap position, consistent with a normal take-off flap setting…position was confirmed from EAFR.”

    • Thrust levers: “Both thrust levers were found near the aft (idle) position. However, the EAFR data revealed that the thrust levers remained forward (take-off thrust) until the impact.”

    These citations do important narrative work. They tell the reader:

    • configuration was normal,
    • thrust was commanded,
    • no stall,
    • no obvious mishandling.

    When digital data would expose air/ground logic, AAIB stops quoting EAFR

    Now compare that to how the report handles systems that determine ground vs air logic:

    • “The landing gear lever was in DOWN position.”
    • “The reverser levers were in the stowed position.”
    • “The wiring from the TO/GA switches and autothrottle disconnect switches were visible, but heavily damaged.”

    These are physical post-crash descriptions, not digital states.

    The report does not quote:

    • digital gear logic,
    • reverser command status,
    • TO/GA engagement state,
    • autothrottle logic state,
    • flight-control mode transitions.

    Yet these are precisely the parameters that would reveal whether the aircraft temporarily reverted to “on-ground” logic while airborne.

    The AAIB report by giving us EAFR data on thrust levers in forward and not EAFR data on “thrust reversers” is playing on the information asymmetry. Because not many people, even in the aviation world, are aware that GE and Safran changed the Boolean gating condition on the 70 GEnx engines (left engine GEnx-1B70/75/P2 and right engine GEnx-1B70/P2) to “OR”.

    For these engines, either forward thrust “OR” thrust reversers can be in “IDLE” for TCMA to activate.

    So, in its desire to divert attention away from the possibility of a TCMA-driven FADEC cutoff, what the AAIB report has inadvertently ended up doing is proving pilot innocence with its selective referencing of black box data. Because if “thrust” was in forward from take-off till crash – it clearly proves pilot integrity and pilot intent; no matter what the system decided otherwise.

    Why “on-ground logic in the air” explains the entire sequence

    Boeing flight-control computers are known to reboot under certain electrical fault conditions. And the FAA warned about this possibility as early as 2016. On reboot, systems enter a fail-safe default state — on-ground logic — before reassessing air/ground status.

    If this occurs after liftoff:

    • autothrottle and TO/GA can disengage,
    • thrust-logic protections can be triggered,
    • FADEC can command fuel reduction or cutoff under TCMA
    • cockpit indications can freeze or reset.

    This is not speculation. It is documented system behaviour.

    And it is the only mechanism that coherently explains:

    • normal liftoff at 08:08:39,
    • sudden loss of thrust logic seconds later,
    • asymmetric engine recovery
    • a cockpit exchange centred on “cutoff”
    • Seemingly “normal” pitch attitude and configuration with catastrophic energy loss.

    RAT: Precision – where safe, Vagueness – where dangerous

    Now, let’s look at how the report mentions emergency power, i.e. the behaviour of the Ram Air Turbine (RAT). The AAIB states that the RAT hydraulic pump began supplying hydraulic power at 08:08:47 UTC — a precise timestamp.

    Yet the AAIB does not give the time for when the RAT deployed, noting only that it appears on CCTV “during the initial climb immediately after lift-off.” In this dark fairytale, time seems selectively unavailable: CCTV footages have no timestamps, the EAFR remembers only some RAT functions but not others. And the moment when RAT started generating electrical power is when AAIB would like us to believe the EAFR turned human and suffered from short-term amnesia.

    The omission of the RAT deployment timestamp is crucial. As in the normal course of events, emergency power, i.e. the RAT, would deploy after the main engines failed. But if RAT deployed when engines were still running, that shows this plane has some underlying electrical disturbance. It also points more towards systems failure than pilot error.

    So, the AAIB uses precision when it does not threaten the fuel narrative. Vagueness appears when it might.

    FADEC: When the AAIB report stops investigating and starts teaching

    After documenting the switch transitions and relight attempts, the AAIB writes:

    “When fuel control switches are moved from CUTOFF to RUN while the aircraft is inflight, each engine’s full authority dual engine control (FADEC) automatically manages a relight…”

    This sentence is not investigative. It is protective.

    Rather than stating what FADEC actually did on AI-171, the report retreats into training manual language, describing how FADEC typically functions — and even mislabeling it as “dual” rather than “digital.” The effect is deliberate: it allows the AAIB to discuss FADEC without committing to any factual finding about its behaviour in this crash.

    In a case now before the Supreme Court, that distinction matters. By giving a generic system description for a specific event, the AAIB has plausible deniability.

    If evidence later emerges that FADEC commanded the fuel cutoff, AAIB can shield itself in the Supreme Court by arguing that it never asserted how FADEC behaved on AI 171 but only talked about how it is designed to behave. This rhetorical move shields the engine-control system from scrutiny at precisely the point where it needs the most investigation.

    This is not a neutral drafting choice. It is how responsibility is deferred without being denied.

    The concealment pattern is quite clear, as the AAIB report:

    • States the aircraft entered air mode at 08:08:39 UTC.
    • Never examines whether it stayed there.
    • Uses EAFR data when it supports “normal take-off”.
    • Avoids EAFR data when it would expose air/ground logic
    • Documents that the aft EAFR’s wiring and connectors were charred — despite the tail section being largely intact — yet offers no causal analysis whatsoever
    • Withholds any forensic findings on soot or residue from the aft EAFR, even though such analysis could distinguish between post-impact fire and a pre-impact electrical arc — a distinction central to determining whether a systems failure occurred before dual engine shutdown
    • Repeats fuel references to steer interpretation
    • Inserts an ambiguous cockpit conversation
    • Substitutes system description for system behaviour when discussing FADEC.
    • Concludes with “no recommended actions” for manufacturers.

    This is not a neutral omission. It is narrative architecture.

    Conclusion: The Human Cost of What This Report Is Written to Hide

    Once the aircraft is acknowledged to be airborne at 08:08:39 UTC, every downstream question should interrogate system logic continuity. The AAIB report does not do that.

    And this is not an abstract failure.

    It has a human face.

    That face belongs to 88-year-old Pushkaraj Sabharwal — a former senior official of India’s Directorate General of Civil Aviation. He gave a lifetime of service to an institution that’s today failed his son – Captain Sumeet Sabharwal; with an AAIB report that’s high on omission and as high on “weaponising selective disclosure of data” – as he puts it.

    At 88, Mr. Sabharwal should have been at peace; in retirement. Instead, he is in court, fighting.

    Fighting not only for his dead son, but also for First Officer Clive Kunders and for the 258 other families who lost a loved one in the first fatal crash of a Dreamliner.

    After 30 years with the DGCA, he knows better than us how accident investigations are supposed to work. And he is asking the right questions. The hard ones like “Why is AAIB giving Boeing and GE a seat at the very table investigating their planes and equipment? Why give them a clean chit?”

    As a former DGCA official, he knows when questions are being avoided, when systems are being protected, and when language is being used to create deniability rather than truth.

    He is watching a preliminary report used to shape public perception before facts are fully disclosed.

    And he is fighting it. Because, as he says, this is about data and due process.
    It is about whether the truth still matters when it is inconvenient.

    Accident investigation is not a bureaucratic exercise. It is a nation’s promise to the dead that their lives will mean something — that lessons will be learned honestly, and that safety will not be sacrificed, as he says to “commercial interests.”

    For India — a founding member of the International Civil Aviation Organisation — this is not acceptable.

    Unless India corrects the course of its investigation, AI-171 will be remembered not only as a catastrophic systems failure in flight, but as a catastrophic failure on the ground — in the very institutions entrusted with the truth.

    For 260 families, this is not justice.
    For global aviation, this is not safety.

    As there are still 1,100 Dreamliners with the same electrical architecture that continue to fly unreviewed and unexamined.

    Because among the people who had faith and trust in India’s aviation regulator to keep our skies safe – were Roshni Songhare, Saineeta Chakravarty, Shradha Dhavan, Aparna Mahadik, Maithili Patil, Manisha Thapa, Nganthoi Kongbrailatpam Sharma, Lamnunthem Singson, Deepak Pathak and Irfan Shaikh – the crew of AI 171 who’d engaged in flight safety demonstrations just a few minutes before the crash.

  • Indian Air Force at 91:  Challenges and Opportunities

    Indian Air Force at 91: Challenges and Opportunities

    The Indian Air Force, created on October 8, 1932, completes 91 years of glorious service as it celebrates the Air Force Day today, October 8, 2023. As the IAF celebrates its annual day with customary elan, it is a time to reflect and assess the future in terms of challenges and opportunities. On the operational front, the die is already cast with two nuclear-powered neighbours, one in political and economic turmoil and the other continuing an aggressive posture. A three-yearlong standoff on the northern border with no signs of reconciliation makes the environment precarious.

    China, with its goal of becoming the leading military power with global reach by 2049, has moved fast to replace and transform its antiquated equipment, systems, and organizations, especially after observing the 1991 Gulf War. Reorganization of the PLA in the last decade, consolidation of forces under one command to oversee military operations against India and creation a Special Support Group (SSG) has enhanced its force application capabilities. Specifically, the upgradation of military infrastructure, airfields, and helipads just north of India is a matter of concern. Robust military hardware production for modern systems and investment in R&D in new-era fields like quantum computing, quantum radars, artificial intelligence, and aircraft and weapon systems development have facilitated significant growth in PLA’s capabilities. Qualitatively and quantitatively, India cannot match the Chinese economy, military hardware, military industry, or infrastructure in the foreseeable future. The only way forward for India is to use its resources in a focused manner to achieve its well-defined strategic goals commensurate with available resources. Lessons from the ongoing Russia-Ukraine war, a contest between unequal forces, are relevant in our context.

    Force Structure Challenges to Overcome

    Besides the operational challenges the Indian Air Force faces on the borders, there are issues related to equipment and organization.

     

    The salience of combat aircraft in battlespace is well known. However, combat aircraft numbers are declining worldwide, with older systems paving the way for modern and more capable platforms. In India, the decline has been rather steep, and replacements are not potent enough to offset the quantity quality. Against an authorization of over 1000 combat aircraft, the Indian armed forces are now in the region of 600. This decline will continue, and by 2030, IAF combat aircraft strength will be down to 450 with the phase-out of MiG-21, MiG-29, Jaguar, and Mirage-2000 fleets. The induction of 36 Rafales, the prolonged induction of LCA, and the planned acquisition of more Su30MKIs will not be able to reverse the declining trend. The ambitious plans for India’s fifth-generation aircraft, AMCA, are still far away. Given this reality, the IAF must make do with, at best, 34-36 fighter squadrons in the 2035 timeframe. It must work on operational strategies based on superior tactics and a local favourable balance of power in case a war is inevitable during this period.

    In the critical area of force multipliers, the numbers have been nearly static since their initial induction in 2003 concerning IL-78 In-Flight Refuellers and in 2010 concerning AWACS. The number of long-range weapons is somewhat limited. And in the surveillance and space domains, the resources are meagre. The situation is unlikely to change in the foreseeable future.

    There are positive changes regarding airlift capability, and single-wave airlift capability is gradually increasing with the commencement of induction of the first of the 56 new C-295 transport aircraft replacing vintage Avro. Despite the gradual phase-out of heavy lift Il-76 and light transport aircraft An-32, the fleet of C-17 and C-130 will sustain the requisite airlift capability that enabled the rapid deployment of Indian Army units in Ladakh against PLA build-up. Similarly, the enhanced number of more versatile and potent indigenous helicopters, ALH and LCH, will increase local mobility and firepower.

    The area that is yet to take centre stage is the Unmanned systems. Although the numbers and types increase due to imports, recent conflicts have demonstrated their hugely versatile utility. This aspect needs more attention to offset the capability deficit owing to the reduced number of combat aircraft. Tasks like intelligence, surveillance, reconnaissance, and ground and maritime attack can be effectively performed by unmanned aerial systems, resulting in the release of aircraft for other roles.

    New and more capable radars and integrated networks are replacing the older systems, giving a robust defensive capability. These need to be backed by long-range and quick-reaction surface-to-air weapon systems. Currently, the numbers are limited, and the area to be covered is extensive. Agility in planning, deployment and redeployment is the key to effective defence with limited resources.

    Evolving Battlespace and the Imperative of Jointness

    The battle space is evolving. Conflict hybridization has accelerated the expansion of battlespace, leading to enhanced significance of battlespace transparency. Induction of hypersonic systems, fast relocation of combat elements, and reduced times for systems operationalization have compressed the reaction time. This time-compression for action has tilted the offence-defence balance in favour of the offence. The concept of operations needs to factor in these realities, especially when dealing with a potent and stronger adversary with significant reverse capability.

    Organisationally, the integration of three wings of the Indian armed forces will likely pick up pace in the coming year(s). Integration is now an operational necessity and needs to be fast-tracked. Once theatre commands come into being, the most critical factor will be the allocation and plan of utilization of various combat assets that are limited in numbers but can operate seamlessly between multiple sectors. Will the integration model follow the complex assignment of such resources? That will be suboptimal and possibly counterproductive to enhancing combat capability through integration. IAF will have to make a holistic plan to exploit the full combat potential of its assets, irrespective of how the integration model pans out. Organisationally, this will be the most significant challenge for the men and women in blue in the coming year(s).

    Conclusion

    In the last five decades, India has taken the pole position in money spent on military hardware imports. Saudi Arabia is a distant second, spending less than half of Indian expenditure in this sector. How did India reach here? Public sector monopoly in defence has not yielded the desired results for the last seven decades. Inadequate focus and investment in R&D, captive customers, the Indian armed forces not hand-holding the industry, restrictive policies, monopoly of the public sector, dependency on imported military hardware and inability to leverage large imports for technology access are the factors contributing to this state. Atamnirbhar, from being a rhetoric, is gradually taking shape with orders being placed on Indian enterprises. The policy of earmarking part of the capital budget for Indian manufacturers will undoubtedly encourage the Indian defence industry. Although production efficiency and quality control have been a concern regarding the public sector, things are likely to improve as they face competition from the private sector. The lack of control over critical technologies in areas of aero engines, air-launched weapons, and electronic warfare systems remains a severe vulnerability. Opening the defence sector for private entities, allowing DRDO to share available testing facilities and technology, and creating defence manufacturing corridors are steps in the right direction.

    Capability differential and information differential between the competing sides form the basis of military operations. A classical information matrix about the opposing force includes intent, strategy, military doctrine, and military objectives; besides the overall direction that military strategy gives, an operational plan and its execution are based on an information matrix to achieve defined goals with the least cost or in the minimum possible timeframe. IAF, with its new doctrine IAP2000-22, endeavours to capture the essence of these changes. Indian Air Force needs to be ready with its limited assets and deter war. IAF must augment its limited resources with courage, ingenuity and clever resource employment to outwit the adversary. Given the limited resources and challenges ahead, the IAF will need to be a smart force for efficient management of resources and clever exploitation of force application.

  • The Asymmetric Indo-US Technology Agreement Points to India’s Weak R&D Culture

    The Asymmetric Indo-US Technology Agreement Points to India’s Weak R&D Culture

    Prime Minister Narendra Modi’s state visit to the USA resulted in four significant agreements and the visit is hailed as one of very important gains for India and Indo-US strategic partnership. The focus has been on defence industrial and technology partnership. Media and many strategic experts are seeing the agreements as major breakthroughs for technology transfers to India, reflecting a very superficial analysis and a lack of understanding of what really entails technology transfer. Professor Arun Kumar sees these agreements as a sign of India’s technological weakness and USA’s smart manoeuvring to leverage India for long-term defence and technology client. The visit has yielded major business gains for USA’s military industrial complex and the silicon valley. Post the euphoria of the visit, Arun Kumar says its time for India to carefully evaluate the relevant technology and strategic policy angles.

     

    The Indo-US joint statement issued a few days back says that the two governments will “facilitate greater technology sharing, co-development and co-production opportunities between the US and the Indian industry, government and academic institutions.” This has been hailed as the creation of a new technology bridge that will reshape relations between the two countries

    General Electric (GE) is offering to give 80% of the technology required for the F414 jet engine, which will be co-produced with Hindustan Aeronautics Limited (HAL). In 2012, when the negotiations had started, GE had offered India 58%. India needs this engine for the Light Combat Aircraft Mark 2 (LCA Mk2) jets.

    The Indian Air Force has been using LCA Mk1A but is not particularly happy with it. It asked for improvements in it. Kaveri, the indigenous engine for the LCA under development since 1986, has not been successful. The engine development has failed to reach the first flight.

    So, India has been using the F404 engine in the LCA Mk1, which is 40 years old. The F414 is also a 30-year-old vintage engine. GE is said to be offering 12 key technologies required in modern jet engine manufacturing which India has not been able to master over the last 40 years. The US has moved on to more powerful fighter jet engines with newer technologies, like the Pratt & Whitney F135 and GE XA100.

    India is being allowed into the US-led critical mineral club. It will acquire the highly rated MQ-9B high-altitude long-endurance unmanned aerial vehicles. Micron Technologies will set up a semiconductor assembly and test facility in Gujarat by 2024, where it is hoped that the chips will eventually be manufactured. The investment deal of $2.75 billion is sweetened with the Union government giving 50% and Gujarat contributing 20%. India is also being allowed into the US-led critical mineral club.

    There will be cooperation in space exploration and India will join the US-led Artemis Accords. ISRO and NASA will collaborate and an Indian astronaut will be sent to the International Space Station. INDUS-X will be launched for joint innovation in defence technologies. Global universities will be enabled to set up campuses in each other’s countries, whatever it may imply for atmanirbharta.

    What does it amount to?

    The list is impressive. But, is it not one-sided, with India getting technologies it has not been able to develop by itself.

    Though the latest technology is not being given by the US, what is offered is superior to what India currently has. So, it is not just optics. But the real test will be how much India’s technological capability will get upgraded.

    Discussing the New Economic Policies launched in 1991, the diplomat got riled at my complaining that the US was offering us potato chips and fizz drinks but not high technology, and shouted, “Technology is a house we have built and we will never let you enter it.”

    What is being offered is a far cry from what one senior US diplomat had told me at a dinner in 1992. Discussing the New Economic Policies launched in 1991, the diplomat got riled at my complaining that the US was offering us potato chips and fizz drinks but not high technology, and shouted, “Technology is a house we have built and we will never let you enter it.”

    Everyone present there was stunned, but that was the reality.

    The issue is, does making a product in India mean a transfer of technology to Indians? Will it enable India to develop the next level of technology?

    India has assembled and produced MiG-21 jets since the 1960s and Su-30MKI jets since the 1990s. But most critical parts of the Su-30 come from Russia. India set up the Mishra Dhatu Nigam in 1973 to produce the critical alloys needed and production started in 1982, but self-sufficiency in critical alloys has not been achieved.

    So, production using borrowed technology does not mean absorption and development of the technology. Technology development requires ‘know-how’ and ‘know-why’.

    When an item is produced, we can see how it is produced and then copy that. But we also need to know how it is being done and importantly, why something is being done in a certain way. Advanced technology owners don’t share this knowledge with others.

    Technology is a moving frontier

    There are three levels of technology at any given point in time – high, intermediate, and low.

    The high technology of yesterday becomes the intermediate technology of today and the low technology of tomorrow. So, if India now produces what the advanced countries produced in the 1950s, it produces the low-technology products of today (say, coal and bicycles).

    If India produces what was produced in the advanced countries in the 1980s (say, cars and colour TV), it produces the intermediate technology products of today. It is not to say that some high technology is not used in low and intermediate-technology production.

    The high technologies of today are aerospace, nanotechnology, AI, microchips and so on. India is lagging behind in these technologies, like in producing passenger aircraft, sending people into space, making microchips, quantum computing, and so on.

    The advanced countries do not part with these technologies. The World Trade Organisation, with its provisions for TRIPS and TRIMS (Trade-Related Aspects of Intellectual Property Rights and Trade-Related Investment Measures), consolidated the hold of advanced countries on intermediate and low technologies that can be acquired by paying royalties. But high technology is closely held and not shared.

    Advancements in technology

    So, how can nations that lag behind in technology catch up with advanced nations? The Nobel laureate Kenneth Arrow pointed to ‘learning by doing’ – the idea that in the process of production, one learns.

    So, the use of a product does not automatically lead to the capacity to produce it, unless the technology is absorbed and developed. That requires R&D.

    Schumpeter suggested that technology moves through stages of invention, innovation and adaptation. So, the use of a product does not automatically lead to the capacity to produce it, unless the technology is absorbed and developed. That requires R&D.

    Flying the latest Airbus A321neo does not mean we can produce it. Hundreds of MiG-21 and Su-30 have been produced in India. But we have not been able to produce fighter jet engines, and India’s Kaveri engine is not yet successful. We routinely use laptops and mobile phones, and they are also assembled in India, but it does not mean that we can produce microchips or hard disks.

    Enormous resources are required to do R&D for advanced technologies and to produce them at an industrial scale. It requires a whole environment which is often missing in developing countries and certainly in India.

    Enormous resources are required to do R&D for advanced technologies and to produce them at an industrial scale. It requires a whole environment which is often missing in developing countries and certainly in India.

    Production at an experimental level can take place. In 1973, I produced epitaxial thin films for my graduate work. But producing them at an industrial scale is a different ballgame. Experts have been brought from the US, but that has not helped since high technology is now largely a collective endeavour.

    For more complex technologies, say, aerospace or complex software, there is ‘learning by using’. When an aircraft crashes or malware infects software, it is the producer who learns from the failure, not the user. Again, the R&D environment is important.

    In brief, using a product does not mean we can produce it. Further, producing some items does not mean that we can develop them further. Both require R&D capabilities, which thrive in a culture of research. That is why developing countries suffer from the ‘disadvantage of a late start’.

    A need for a focus on research and development

    R&D culture thrives when innovation is encouraged. Government policies are crucial since they determine whether the free flow of ideas is enabled or not. Also of crucial importance is whether thought leaders or sycophants are appointed to lead institutions, whether criticism is welcomed or suppressed, and whether the government changes its policies often under pressure from vested interests.

    Unstable policies increase the risk of doing research, thereby undermining it and dissuading the industry. The result is the repeated import of technology.

    The software policy of 1987, by opening the sector up to international firms, undermined whatever little research was being carried out then and turned most companies in the field into importers of foreign products, and later into manpower suppliers. Some of these companies became highly profitable, but have they produced any world-class software that is used in daily life?

    Expenditure on R&D is an indication of the priority accorded to it. India spends a lowly 0.75% of its GDP on R&D. Neither the government nor the private sector prioritises it. Businesses find it easier to manipulate policies using cronyism. Those who are close to the rulers do not need to innovate, while others know that they will lose out. So, neither focus on R&D.

    Innovation also depends on the availability of associated technologies – it creates an environment. An example is Silicon Valley, which has been at the forefront of innovation. It has also happened around universities where a lot of research capabilities have developed and synergy between business and academia becomes possible.

    This requires both parties to be attuned to research. In India, around some of the best-known universities like Delhi University, Allahabad University and Jawaharlal Nehru University, coaching institutions have mushroomed and not innovative businesses. None of these institutions are producing any great research, nor do businesses require research if they can import technology.

    A feudal setup

    Technology is an idea. In India, most authority figures don’t like being questioned. For instance, bright students asking questions are seen as troublemakers in most schools. The emphasis is largely on completing coursework for examinations. Learning is by rote, with most students unable to absorb the material taught.

    So, most examinations have standard questions requiring reproduction of what is taught in the class, rather than application of what is learned. My students at JNU pleaded against open-book exams. Our class of physics in 1967 had toppers from various higher secondary boards. We chose physics over IIT. We rebelled against such teaching and initiated reform, but ultimately most of us left physics – a huge loss to the subject.

    Advances in knowledge require critiquing its existing state – that is, by challenging the orthodoxy and status quo. So, the creative independent thinkers who generate socially relevant knowledge also challenge the authorities at their institutions and get characterised as troublemakers. The authorities largely curb autonomy within the institution and that curtails innovativeness.

    In brief, dissent – which is the essence of knowledge generation – is treated as a malaise to be eliminated. These are the manifestations of a feudal and hierarchical society which limits the advancement of ideas. Another crucial aspect of generating ideas is learning to accept failure. The Michelson–Morley experiment was successful in proving that there is no aether only after hundreds of failed experiments.

    Conclusion

    The willingness of the US to provide India with some technology without expecting reciprocity is gratifying. Such magnanimity has not been shown earlier and it is obviously for political (strategic) reasons. The asymmetry underlines our inability to develop technology on our own. The US is not giving India cutting-edge technologies that could make us a Vishwaguru.

    India needs to address its weakness in R&D. As in the past, co-producing a jet engine, flying drones or packaging and testing chips will not get us to the next level of technology, and we will remain dependent on imports later on.

    This can be corrected only through a fundamental change in our R&D culture that would enable technology absorption and development. That would require granting autonomy to academia and getting out of the feudal mindset that presently undermines scientific temper and hobbles our system of education.

  • New ‘Drone Rules’ is set to transform Drone business in India

    New ‘Drone Rules’ is set to transform Drone business in India

    Not many would know that Goldman Sachs has predicted that in the next five years the drone market will be worth over a hundred billion US dollars. India became an IT hub in the 1990s and Indian programmers were sought-after during the dot-com boom. This was not because of some great policy decisions that we took at that time but rather it was because of no policy on the subject. There were times when computers gathered dust in some ministries because the minister felt computers are sinister equipment that could take away people’s livelihood.

    ‘Drones’ are said to be the next big thing that the world has ever seen since IT and Dotcom in terms of technology disruption and touching the lives of people in all spheres. Traditional modes of transportation of goods, surveillance, survey, and foraying into newer areas like agriculture, marine et cetera are some areas where the drone is already making waves.

    The recent ‘Draft Drone Rules’, released for public comments by the civil aviation ministry, is a welcome change from the previous one which gave the impression that obtaining a license would be a herculean task. Some companies like AutomicroUAS Aerotech Pvt ltd and many others did obtain a license using provisions of the previous policy. The new draft policy is a more user and business-friendly drone policy. This is a very good and the first decision by the new civil aviation minister, Jyotiraditya Scindia, after assuming office.  Some of the highlights of the new drone policy are: –

    • Up to 500 kgs of drone Aircraft Rules, 1937 is no more applicable. This is a significant change because the Aircraft rules 1937 is specifically applicable for airplanes that carry humans and therefore, have been made with that purpose.
    • There are a significant number of people who fly nano and micro drones in India. Including operators of model aircraft. Ubiquitous drones include drones flying at marriage parties and increased use of drone shots in the entertainment field. These people now can fly these drones/model aircraft without having a drone pilot license. This singular step itself will bolster not only self-employment but also reduce unemployment in the country. Being a drone pilot is also looked at as one of the coolest things today.
    • Drone imports will still be controlled by DGFT (director-general foreign trade). This currently could be looked at as a bit of an impediment for those entrepreneurs who are dependent on imports of certain drone parts. However, in the long run, this provision could bolster making those parts in India and selling them abroad. Easing of import of drones/drone parts currently and bringing in stricter rules as time goes by would have been a better option. This aspect could be looked at by the government to promote innovators and children who are looking to learn, for who importing certain critical drone components is vital. It is highly recommended that drone imports controlled by DGFT be done away with for the time being.
    • The creation of a drone corridor is likely to change the face of the Indian Economy. Logistics Operation, last-mile connectivity, the short haul of goods between two towns, and the cost of connectivity between places are set to change dramatically. This change alone, in my opinion, is likely to bring a significant impact in times to come. Not many have realized the power of creating drone corridors and all that remains to be seen is how this rule is taken forward by the government in improving logistics connectivity and creation of drone highways in times to come.
    • The drone research and development Organisation as a provision in the rule is futuristic and is likely to change the face of the drone industry in India. Correctly harnessed and nurtured, this rule could enable the development of many centres of excellence of drones. The government needs to create an equivalence of ‘Silicon Valley’ for the drones so that organisations dealing with hardware, software, artificial intelligence et cetera can come together and take this endeavour forward.
    • There are several companies across the world that are working on unmanned traffic management (UTM) including an Indian company called Avianco. These companies now could collaborate with the government of India in providing unmanned traffic information and could work as a service provider for tracking of drones as well as providing drone operators with simple NPNT permission, which is one of the provisions in the new drone policy.
    • Third-party drone insurance could be adequate as specified in the rules. However, drones are costly equipment. Readers would be surprised to know that most of these drones are costlier than small hatchback cars. Therefore, owners of these drones may want to go for comprehensive insurance. This is a huge opportunity for insurance and insurance facilitation companies like TropoGo, in the area of drone insurance. In times to come, the number of drone insurance policies may well overtake the number of vehicle insurance policies in the world. Since drones are set to replace many of the traditional workforce and industries.
    • ‘Drone promotion Council’ as specified in these rules should have come up as of yesterday, but it’s never too late. Those countries who missed this ‘Drone-Bus’ may get left behind in the overall economic progress in times to come. Therefore, setting up the ‘drone promotion council’ is the need of the hour.
    • Highlights of the new ‘Draft Drones Rules’ are shown below:

     

    The new drone policy of India is a welcome change. It is a well-thought-out, simplified policy that India has seen in recent times. This policy aligns with Prime Minister Modi‘s vision for India in terms of reducing unemployment, improving ease of doing business, self-employment, making India go digital, and becoming a technology leader in the world. What the future holds will entirely depend on how these rules are interpreted and implemented efficiently without the usual horrors of the red-tapism of the past.

  • Drone Threats: Detecting and Countering Them

    Drone Threats: Detecting and Countering Them

    The drone attack at the Jammu airbase in the early hours of Sunday, June 27, was a first-of-its-kind in India. It has rattled the security forces, but more than that, it has shown how acts of terror can be perpetrated in the future. To get battle-ready, we need to understand the different kinds of drones, how they work and how lethal they can be.

    Size Matters

    Drones come in different sizes and shapes. Their major classification is fixed-wing and rotary-wing. They can be classified as per:

    1. Weight
    2. Function
    3. Area of application

    In India, the Ministry of Civil Aviation (MoCA) classifies them as per their weight. Drones weighing below 250 gms are called nano drones, above 250 gms but below 2 kgs are called micro drones, above 2 kgs but below 25 kgs are small drones. Anything above 25 kgs is a large drone, as per MoCA in India.

    Small toy drones can be classified as nano drones. Although these nano drones can be quite lethal in intelligence gathering, like armed drones without artificial intelligence and machine learning (AI/ML) (which would give it pinpoint accuracy), they aren’t lethal. Most countries have exempted these drones from the legal gamut because they largely fall in the toy category. However, swarms of these drones designed to explode and controlled by a mother ship can be quite lethal. And currently, no countermeasures to such drones exist. Recently, F/A-18 Hornet launched such a swarm to demonstrate the capability of such nano drones.

    Equation quickly changes in the micro drone category. As the weight of the drone increases, so does its lethality, and being a manageable size, these drones have found favour with many enthusiasts. These are the class of drones that were researched by the open source communities in the early 2000s. They indeed ushered in the age of drones. Designed well, they have an endurance limit of over 40 minutes and can travel in an autonomous mode for over 30 km one way. Mostly made of plastics, polymers, these drones can be difficult to detect and prosecute.

    Small drones are the ones that are increasingly being used by anti-national elements. Be it to drop contraband, weapons, or to carry out a Kamikaze-style attack. Even the low-end of small drones (up to 6 kgs) can carry an adequate amount of explosives to cause serious damage. These are also the drones that are used in helping humanity. These drones can be fixed-wing, rotary-wing, or hybrid.

    To own and fly a drone weighing more than 250 gms and less than or equal to 25 kgs, whether, for commercial or recreational purposes, one would need Operator Permit-I. To get this permit one needs to go through the due diligence process of the DGCA (Directorate General of Civil Aviation), MoCA.

    The same procedure applies if you want to become a drone pilot in India. The due diligence, examination, and certification process is similar to that of a manned aircraft pilot. The only difference, you just need to clear the 10th standard exams to become a drone pilot. The due diligence process includes paperwork like police verification, checking Aadhaar, and passport details, among other things. Therefore, only a bonafide citizen of India with no criminal record can become a drone pilot in India.

    How to Counter Drones

     Drones can be countered through three methods, namely:

    1. By jamming the drone controller frequency (2.4 GHz, 5.8 GHz, occasionally 433 MHz and 900 MHz).
    2. By jamming the GNSS or Global Navigation Satellite Systems, like GPS, GLONASS, GAGAN, the Indian Regional Navigation Satellite System, also known as NAVIC, etc.
    3. The hard kill option of shooting the drone down using guns, lasers, and electromagnetic guns always exists.

    To counter drones, you need to detect them first. It can be done in three ways, namely:

    1. Use drone radar: It works like a conventional radar, which sends out energy and looks for reflected energy to pick up these drones. Challenge however is that the reflected energy from the small drones is so low that it becomes impossible to pick nano and micro drones with drone radars.
    2. Pick up drone control signal: Picking up drone control signals is fairly easy because they operate in the ISM (industrial, scientific, and medical) band of frequencies. However, most WiFi and other equipment work on this frequency, and separating drone frequency signatures from these becomes a challenge.
    3. Pick up noise generated by the propeller tips: This is another method to pick up drones. In ideal conditions, it has proven effective in picking up drones at a very large range. However, the challenge is if the ambient noise is higher and ambient conditions are not suitable, drones don’t get picked up at all.

    Drones for Good

     Drones today are being used for a variety of services, beyond the military.

    1. Disaster relief and humanitarian assistance: Drones are proving to be indispensable in this area. Be it floods, forest fire, COVID assistance or locust control, drones are everywhere, doing what they do, silently.
    2. In scientific quest: Drones are doing a wonderful job in this area, be it marine applications, studying agriculture, soil/ water pollution, carrying out weather surveys, name an area and drones can be put to task.
    3. In the entertainment industry: Drones have replaced expensive helicopters, and today even the producer of a low-budget show can get a drone shot at minimum cost. As a result, drone shots are now seen in shows and movies more than ever.

    Tip of the Iceberg

    Drones for good far outweigh the application of drones for anti-national and terror activities. The drone industry needs to be nurtured if any country aspires to become an economic giant in the future. No wonder Goldman Sachs has said that the $100-billion drone industry is just the tip of the iceberg in terms of its business potential over the next five years.

  • Retrofit Winglets for Wind Turbines

    The benefits of using winglets on wind turbines has been well documented. However, adding winglets to wind turbine blades leads to significant increases in blade root bending moments, requiring expensive structural reinforcement with cost and weight drawbacks. A unique design philosophy for retrofitting winglets on existing wind turbines is presented. These retrofit winglets offer an increase in power produced without the need for structural reinforcement. Predicted performance and cost benefits are illustrated via a study using the NREL 5MW reference wind turbine. The addition of winglets resulted in a 2.45% increase in Coefficient of Power (Cp) and 1.69% increase in Annual Energy Production (AEP).

    Nomenclature

    Cp = coefficient of power

    V¥ = freestream velocity

    𝑟i = blade section radius

    𝜃t = blade section twist

    𝐼$ = Initial Cost per year

    𝑀$ = Annual Operating Expense

    Et = Annual Energy Output

    I. Introduction

    The idea of winglets on wind turbines is one that has been periodically explored in the past few decades. The earliest studies incorporating blade tip devices on wind turbines were done by Gyatt and Lissamann1. Drawing from advanced tip shapes that were being applied to fixed wing aircraft to reduce drag, the authors tested four tip designs on a 25kW Carter Wind Turbine in San Gorgonio Pass, California. Further studies were carried out in subsequent decades. Van Bussel2 developed a simple momentum theory for blade winglet configurations. Imamura et al.3 analyzed the effects on winglets on wind turbines using a free-wake vortex lattice method. Guanna and Johansen4 developed a free wake lifting line model to compute the effects of winglets, comparing it with CFD results obtained using EllipSys3D. Johansen and Sorenson5 did further studies on increasing power coefficient with the use of winglets, showing that adding winglets definitely changes the downwash distribution, leading to an increase in the power produced by a wind turbine.

    While the benefit of adding winglets has been well documented, there are drawbacks to adopting the traditional method of doing so. The addition of large, heavy winglets to maximize aerodynamic benefit leads to significant increases in root bending moments. Imamura et al.6 analyzed the effects of winglets on wind turbine blades using a free-wake vortex lattice method. Their study showed that a winglet at an 80°cant angle and height of 10% of the rotor radius resulted in a 10% increase in the blade root flapwise bending moment. This situation may require blade structural reinforcement, making winglets an expensive and often infeasible proposition. In order to address this, a novel design philosophy has been developed, allowing the use of retrofit winglets that offer an increase in power produced, but without the need to structurally reinforce the blade. This paper outlines the design philosophy, tools

    used and results from initial simulations.

    II. Design Philosophy for Retrofit Winglets

    The key differentiator between this study and prio winglet studies is the design philosophy: designing a lightweight winglet at minimum cost that, while providing an improvement in the turbine’s Coefficient of Power (Cp), does not require blade structural reinforcement. Such a winglet does not seek to maximize Cp, but rather minimize blade bending moments with an acceptable increase in Cp. This is accomplished by balancing the centrifugal force and aerodynamic normal force generated by the winglet. Balancing forces minimizes increases in blade root bending moment, negating the need for an exceptionally strong winglet and allowing it to be light, and requiring noreinforcement of the main blade. Savings in weight are strongly related to cost, so a lighter winglet implies a cheaper, more cost effective one. Accordingly, the best winglet is not one that offers the maximum increase in Cp, but rather offers an increase in Cp while ensuring forces are balanced within a threshold. Figure 1 presents a freebody diagram of the retrofit winglet. A qualitative plot highlighting the design philosophy and the optimal design space is presented in Figure 2. To be able to guage the effects of winglets developed using the mentioned design philosophy, it was decided to use the NREL 5MW wind turbine7 as a reference turbine, and implement a vortex lattice method and cost function to evaluate aerodynamic efficacy and feasibility. The NREL 5MW reference wind turbine is a conceptual three-bladed upwind turbine that was primarily designed to support concept studies. It is heavily based on the Repower 5MW wind turbine; however, in cases where detailed information is not available, data from publicly available conceptual studies is used.

  • Evaluating the Make in India Policy for Defence Manufacturing and Technology Acquisition

    Evaluating the Make in India Policy for Defence Manufacturing and Technology Acquisition

    Led by the Department of Industrial Policy & Promotion, Ministry of Commerce, the Make in India policy (“MII”) extends to 25 focused sectors. Among these is the defence sector, where the nature of the sector renders MII extremely important and relevant. This is outlined by India’s status as the second-largest standing army and third-largest military spender in the world.[1] Yet, it remains the second-largest arms importer and its exports merely amount to 0.2% of the global pie.[2] China is the fifth-largest arms exporter at 5.5% of the global share.[3] However, this is likely to fall in the post-pandemic world, where China’s credibility has been severely tainted.[4] This represents an opportunity for Indian defence manufacturers to attract present and future foreign investment.

    Against this background, MII was enacted with two objectives: (1) to increase domestic manufacturing of defence equipment; and (2) address the national security interest of self-sufficiency over key technologi. There are two ways in which technology up-gradation can happen: (1) indigenous efforts; and (2) transfer of technology, through international agreements. In this article, I flag the main challenges to argue that India has significantly underperformed in both. Subsequently, I propose macro-policy changes to address identified challenges.

    Evaluating technological upgradation in the Defence sector in india

    1. Evaluating ‘Indigenous Efforts’

    Indigenous efforts are confronted with three main challenges:

    • Inadequate Investment for Research & Development (R&D)

    Only 5.7% of the defence budget is allocated to R&D,[5] despite successive parliamentary committees recommending at least 10% to meet minimum requirements.[6] The average allocation among global rivals like USA, UK, France, and China is well above 15%.[7] Even private-sector players in India, like Tata, L&T, and Mahindra and Mahindra, invest less than 1% of their turnover in R&D, as against the average of 10% in the aforementioned countries.[8] The producer lacks the basic R&D required even for making marginal improvements in performance to the product, or altering it based on user-specifications.[9] The effect of this is that the resulting product is obsolete in an already disruptive market. Thus, a buyer, even if domestic, is unwilling to accept such an obsolete product at higher prices merely for the sake of indigenous production.

    • Shortage of Skilled Workforce

    A skilled workforce is the key to achieving self-sufficiency in defence manufacturing because of the highly specialized nature of this sector and the workforces’ vision and skills determine the efficacy of the produced/procured domestic technology. This shortage exists at both the research and procurement level.

    At the research level, there is a severe shortage of skilled human resources, in terms of quantity and quality, at R&D organizations like DRDO.[10] With more than 3,500 engineering colleges producing about 1.5 million engineering graduates annually, India has an unparalleled talent availability.[11] However, only 17.5% of these graduates are employable because colleges lack proper infrastructure and faculty,[12] along with current curriculum ignoring industry skills, defined career paths, and evolving technologies.[13] Thus, organizations are compelled to spend significantly in making fresh talent “employable”.

    While India has a decent pool of highly qualified low-cost engineers and scientists,[14] they are unwilling to work in the public sector due to limited opportunities and low growth potential,[15] where most defence R&D is undertaken. As the departure of 132 scientists in the last five years from DRDO shows,[16] even those employed mostly do not continue long-term due to better opportunities elsewhere.[17] The contribution of most of these scientists has been limited to the production of academic articles,[18] which hasn’t seen any significant and meaningful absorption in the policy. Therefore, the policy has been unable to capture the huge latent employment potential in this sector.[19]

    This position must be contrasted against global competitors like the US and China, where the highly skilled and employable workforce is significantly and routinely absorbed into the most impactful R&D organization, whether private or public.[20] Moreover, unlike other leading countries, India lacks any training and education infrastructure specialized for R&D personnel in the defence sector. These countries have developed specialist defence schools that have managed to produce large pools of exclusive talent. France itself has managed to produce 134,000 specialist employees.[21]

    At the procurement level, the asset acquisition process is not tasked to a dedicated cadre of the workforce.[22] Further, there are no educational or training programs for employees involved in this process.[23] Thus, there is the loss in terms of the benefits of specialization, especially in a sector where progress is characterized by specialization.

    • Limited Involvement of the Private Sector

    There is a significant lack of incentive for greater private sector involvement. The private sector is commercially motivated to establish its manufacturing base only when it has a good chance, or preferably guarantee, of getting frequent and sizeable orders.[24] However, the current manufacturing and procurement process has ignored this motivation but is also completely converse to it.

    As the BJP government’s Rafale fiasco indicates, the procurement processes lack transparency, and frequently fraught with allegations and counter-allegations.[25] This disincentivizes both domestic and global private sector players from conducting business.

    Despite unprecedented inclusion of the private sector, it is widely believed in the private sector that the government is biased towards public sector undertakings, denying a level-playing field for the private sector and even denying opportunities to bid.[26]

    The government’s Strategic Partnership Model, aimed at inviting world-class defence giants to collaborate with Indian entities, has unduly restricted autonomy. Under this program, the government chooses the Indian partner for the foreign OEM, without consulting them.[27] Global defence giants, like Airbus, Lockheed Martin, ThyssenKrupp, and Dassault, have shown interest in contracting with the Indian private sector.[28] However, it is a combination of these factors that this interest has largely failed to materialise into successfully concluded deals.

    Even where, despite these disincentives, the private sector has been involved, this has been in non-critical and less required areas. Most of India’s defence imports are in the category of major platforms such as fighter aircraft, helicopters, naval guns, and anti-submarine missiles.[29] However, the private sector initiatives are predominantly in the category of ammunitions (including rockets and bombs), and surveillance and tracking systems.[30]

    1. Evaluating ‘Transfer of Technology’

    There has been no transfer of technology (“ToT”) in the critical defence procurement process. All major contracts under MII have been “off the shelf”, and without any crucial ToT.[31] As per the CAG Report, between 2007 and 2018, the government concluded 46 offset contracts but failed to implement the ToT agreements in any of them.[32]

    The failure here can be attributed to successive governments unduly hoping that India’s status as a large arms importer would necessarily make international players compliant as regards sharing their intellectual property (“IP”). While foreign companies have shown interest in contracting with Indian players, the large purchase orders have been inadequate to incentivize foreign players to share their IP.[33]

    The government has also been overly ambitious of ToT as a means of technology upgradation. Even implementing the negotiated ToT is not the end because the more challenging issues of absorption of this technology and ownership of IP remain.[34] Moreover, the ToT route provides India only with the ‘know-how’, without any insight into the ‘know-why’.[35] As India’s acquisition of the Sukhoi Su-30 has shown, the public sector is critically dependent on the OEMs, here the Russians, for even minor systemic upgradations.

    Way Forward

    The government must increase allocation to defence R&D to at least 10% and must incentivize greater contributions from the private sector. Existing capabilities and services at training and diploma centres must be upgraded through public-private partnerships. There must be a separate and devoted institutional structure for all procurement-related functions. The procurement policy must also aim at buying talent, besides technology, to bridge technology gaps. The education curriculum at engineering universities needs to be modernized, with a focus on employability. Specialist defence schools must also be established. However, it is most important that the public sector aims at retaining its talent through unique and lucrative incentive structures.

    To incentivize the private sector through minimum order guarantees, the government must utilize ‘public procurement of innovation’. Under this policy tool, the government uses its exchequer to artificially generate demand for an emerging innovative solution, unavailable on a commercial scale.[36] The private sector can further be incentivized by streaming the procurement and dispute resolution process. As for procurement, a fast-track procedure with single-window clearances can be adopted.[37] As for dispute resolution a permanent arbitration tribunal must be established to expeditiously settle disputes with finality.[38]

    Conclusion

    Firstly, the indigenous efforts at technology up-gradation have failed due to limited R&D output, shortage of skilled workforce, and limited private sector involvement. The R&D budgetary allocation is way below the recommended and global standard. The shortage of skilled workforce is both at the research and procurement due to a lack of education and training infrastructure specific to the defence sector, low employability among most graduates, and unwillingness to work in the public sector among highly qualified graduates. The private sector has been disincentivized due to a lack of order guarantees, the unrealistic and retroactive manner of the procurement process, the constant allegations and counter-allegations, and the continued bias towards the public sector. Moreover, the private sector has been involved in non-critical and less required areas.

    Secondly, while the government has concluded ToT agreements, it has been inefficient in enforcing them. Moreover, even if this were to succeed, it has not established any action plan for absorbing this technology and addressing ownership of IP. It has also been overly ambitious of the utility of ToT.

    The forthcoming virtual summit between Indian Prime Minister Narendra Modi and Australian Prime Minister Scott Morrison assumes considerable significance for an India-Australia strategic partnership, particularly as it comes against the backdrop of heightened friction with China for both countries. Enhanced defence cooperation between the two countries could be an important signal to Beijing of the costs of overly assertive strategic behaviour – whether in the Himalaya or in trade. For some years, defence cooperation has largely focused on the naval relationship. Now is the time for enhanced air-power cooperation.
