Flight AI 690 Operational Details
The flight originated from Delhi Indira Gandhi International Airport with a scheduled landing at Kozhikode Calicut Airport. Final approach occurred during a convective weather episode, with reported visibility constraints and runway condition concerns.
Departure and Cruise Phase
Departure was routine, with normal cruise altitude and speed maintained. Communication with air traffic control remained within standard protocols until descent initiation.
Descent and Approach Challenges
Approach clearance was received, and the crew navigated significant rain cells. Instrument approaches were in use, yet deviations occurred that challenged the stabilized approach criteria.
Pilot Decisions and Stabilized Approach Criteria
Pilot decision-making during the final approach became a focal point of analysis. Stabilized approach parameters, including glidepath alignment and airspeed tolerance, were not consistently maintained.
Weather Interpretation and Go-Around Considerations
The crew faced challenges interpreting real-time weather updates and assessing whether to continue the approach or initiate a go-around. Regulatory guidance emphasizes aborting the landing when predefined limits are exceeded.
Control Inputs and Terrain Impact
Late control corrections, coupled with terrain proximity, resulted in an excursion beyond the runway threshold. The aircraft struck an embankment and a road, leading to loss of structural integrity and fire propagation.
Safety Implications and Regulatory Response
The accident triggered reviews across Indian aviation oversight bodies, emphasizing enhanced monitoring of approach decisions and ground proximity warning systems. Air India faced operational scrutiny alongside broader industry reforms.
Training and Procedure Updates
Regulators mandated refresher training on stabilized approaches, weather decision-making, and go-around procedures. Aircraft-specific guidance was reinforced to address recurrent challenges at hilly airports.
Infrastructure and Alert Systems
Calls for improved runway end safety areas and enhanced terrain awareness arose alongside recommendations for better dissemination of localized weather observations at regional airports.
Compensation and Passenger Rights
Passenger families pursued compensation through statutory frameworks aligned with international air law. The airline’s response intersected with legal processes and public expectations around accountability.
Financial Repercussions and Assistance
Support mechanisms included interim relief, travel facilitation for repatriation, and coordination with diplomatic channels. Compensation amounts were determined through adjudicative forums, reflecting prevailing tariff norms and liability ceilings.
Long-term Advocacy and Memorial Initiatives
Civil society groups emphasized transparent communication, victim dignity, and sustained advocacy for systemic improvements. Commemorative events underscored the human dimension often overshadowed by technical investigations.
A Path Toward Enhanced Operational Vigilance
- Review and enforce stabilized approach criteria consistently at all stages of flight.
- Upgrade airport weather observation and dissemination systems for regional carriers.
- Expand mandatory training on go-around procedures and terrain awareness for pilots operating into hilly airports.
- Strengthen runway end safety infrastructure and continuous risk assessment protocols.
- Promote transparent investigations and victim support mechanisms to build stakeholder trust.
FAQ
Reader questions
Why did the aircraft go beyond the runway at Kozhikode?
The aircraft overran the runway due to a hard landing during heavy rain, reduced braking action, and a late go-around decision that prevented sufficient runway length to stop safely.
What role did weather play in the Air India crash 2018 at Kozhikode?
Heavy rain and thunderstorms reduced visibility and runway friction, complicating the approach and contributing to unstable conditions that challenged safe operations.
Were the pilots criticized for their decisions during the approach?
Investigations indicated that the crew faced difficulties in maintaining a stabilized approach and that a go-around should have been called earlier given deteriorating conditions and deviations.
What changes were implemented after the Air India crash 2018 to prevent similar accidents?
Regulators introduced stricter stabilized approach enforcement, enhanced weather reporting at regional airports, improved terrain awareness requirements, and revised crew training protocols.
