Behind the recent disruptions faced by IndiGo is an operational reality, Pg13

Key Highlights:

• IndiGo faced operational disruptions in early December due to new Flight Duty Time Limitation (FDTL) rules.
• The DGCA granted IndiGo a temporary exemption until February 10 to stabilize operations.
• IndiGo dominates night flights (12 am - 6 am), accounting for over 60% of domestic arrivals and departures.
• The new FDTL norms capped pilot landings during night duty, disproportionately impacting IndiGo.
• DGCA has ordered IndiGo to curtail its domestic flight schedule by 10 per cent.

Detailed Insights:

• The new FDTL rules define night duty as any duty between 12 am and 6 am, limiting pilots to a maximum of two landings during this period, aiming to reduce pilot fatigue.
• IndiGo's extensive network and higher frequency of night flights made it particularly vulnerable to the new regulations, requiring more complex crew rostering and standby pilots.
• Despite the new rules being stipulated nearly two years prior, IndiGo increased its flight schedule, including night flights, without adequately expanding its pilot workforce.
• IndiGo was short of 65 captains for its Airbus A320 fleet, leading to flight cancellations and passenger disruptions, with the airline admitting to misjudgments in implementing the new rules.
• Competitors were better prepared, having adjusted their networks and pilot availability, benefiting from stronger pilot bench strength relative to fleet size.
• The DGCA is investigating the disruptions, and IndiGo is conducting an internal investigation, with plans to scale up operations to around 2,200 daily flights by March 2026.
• The new rules have a cascading impact, requiring airlines to roster more pilots throughout the day, not just during the night window, due to the crew landing cap.

Key Concepts Involved:

• Flight Duty Time Limitation (FDTL): Regulations governing the maximum working hours and minimum rest periods for flight crew to manage fatigue and ensure flight safety.
• Directorate General of Civil Aviation (DGCA): The regulatory body in India responsible for overseeing aviation safety, licensing, and compliance with aviation regulations.
• Window of Circadian Low (WOCL): The period between 2 am and 6 am when the human body experiences a natural decline in alertness and cognitive function, increasing fatigue.
