Technical snag at Delhi airport

On Friday, Delhi's Indira Gandhi International airport was hit by a major technical snag that led to delays of over 800 domestic and international flights. Twenty flights were also cancelled due to the failure of Automatic Message Switching System (AMSS), cutting off automatic transmission of flight plan data to air traffic controllers’ screens.

The Airports Authority of India (AAI) cited a “technical issue” with the AMSS as they shared updates on the status. However, there was no clarity on what the issue was or what caused it. The authorities only said that the technical issue caused delays in processing flight plan messages thus causing flight delays.

The glitch left passengers high and dry at the Delhi airport as many of them told HT that the food at airport was too expensive as they waited for the flights to resume for as long as 12 hours.

To be sure, IGI airport, one of India’s busiest, manages over 1,500 flight movements each day.

Passengers, frustrated with a slew of malfunctions to have ailed IGI airport in the last few months, were left fuming once again – with many wondering if this is how an international airport located in the Capital of a country should function. The issue was finally resolved late evening.
