Flight operations at Delhi’s Indira Gandhi International Airport (IGIA) were thrown into disarray on Friday after a technical snag hit the Air Traffic Control (ATC) system, delaying more than 800 flights and stranding hundreds of passengers across terminals. Sources said the disruption, which began late Thursday, affected the Automatic Message Switching System (AMSS), a crucial communication network that feeds data to the Auto Track System (ATS), which generates flight plans for controllers. However, the AMSS system was restored by late Friday evening.“Flight operations at Delhi Airport has been disrupted due to an ongoing technical issue with the Automatic Message Switching System (AMSS) that supports Air Traffic Control flight planning process. All airline operations at Delhi Airport are currently impacted. Concerned authorities are working on resolving the issue at the earliest,” the Delhi airport authorities said in a passenger advisory.
Much to the delight of passengers, the Airports Authority of India (AAI) said that the AMSS at the airport was restored by late Friday evening.
