Delhi Airport chaos explained: GPS spoofing suspected behind over 400 flight delays

Operations of nearly 400 flights were disrupted – both arrivals and departures – at Delhi’s Indira Gandhi International (IGI) Airport following a technical glitch in the Automatic Message Switching System (AMSS) that handles flight plan messages, forcing controllers to process them manually. The Airports Authority of India (AAI) said in a statement that the issue, detected on November 6, caused delays in processing flight data, but the AMSS systems are “up and functional now”.
