Passengers on IndiGo flight 6E657 experienced a total loss of electricity, cabin lighting, and air conditioning while at Vadodara airport [1], [2].
The incident highlights potential vulnerabilities in ground support infrastructure and the immediate impact of equipment failure on passenger safety and comfort in high-temperature environments.
The blackout occurred while the aircraft was on the ground preparing for its scheduled trip from Vadodara to Delhi [1], [2]. The failure was caused by a technical issue in the Ground Power Unit (GPU), which is the external system that provides electricity to the aircraft when the engines are not running [1], [2].
Passengers were left in darkness and heat for a period of time. While one report indicated the outage lasted more than 30 minutes, other sources said the duration of the power loss was 25 minutes [1], [2]. The lack of ventilation during the blackout caused panic among those on board as temperatures rose inside the cabin.
IndiGo flight 6E657 [1] remained grounded during the outage. The GPU is critical for maintaining cabin environment and powering essential aircraft systems before takeoff. When the unit fails, the aircraft loses its primary source of external power, leaving the cabin dependent on limited backup systems or the activation of the auxiliary power unit.
Airport authorities and airline staff managed the situation until power was restored. The incident serves as a reminder of the critical role ground-based technical systems play in the overall safety and operational efficiency of commercial aviation.
“The aircraft lost electricity, air-conditioning, and cabin lighting, leaving passengers in darkness and heat”
This incident underscores the critical dependency of modern aircraft on ground support equipment. A failure in a Ground Power Unit (GPU) not only disrupts schedules but can quickly create hazardous conditions for passengers, especially in regions with extreme heat where air conditioning is a necessity rather than a luxury.
