The major technical glitch that occurred on Friday morning at Delhi’s Indira Gandhi International Airport (IGI) has now been rectified, but its impact still remains. Despite restoration of AMSS system, delays in more than 800 flights continue. Due to failure of ATC system since morning, there was huge chaos at the airport and passengers had to wait for hours.
There was a problem with the system since two days.
There were intermittent problems in the air traffic control system for the last two days and on Friday morning at around 5:45 am, there was a serious malfunction in the AMSS (Automatic Message Switching System). This system provides data to the flight planning and auto track system. As soon as the system was shut down, ATC had to work in manual mode, which made operations extremely slow.
Flights of all airlines affected
All major airlines like IndiGo, Air India, SpiceJet and Akasa Air reported that their flights were affected due to the ATC system failure. Since Delhi airport handles more than 1,500 flights daily, the impact of the system glitch spread across the network within minutes.

According to Flightradar24, delays were recorded in more than 800 flights. Departing flights are being delayed by an average of 50 minutes to more than an hour. The schedule of arriving flights has also been affected on a large scale. Long queues were seen at the boarding gates and passengers kept waiting for announcements and updates. The atmosphere inside the terminal remained tense due to frequent changes in flight information.

Big meeting at government level, OEM team also present on the spot
As soon as information about the malfunction was received, an immediate meeting of the Secretary of the Civil Aviation Ministry, AAI Chairman and senior officials was called.

AMSS system restored, it will take time to clear the backlog
According to AAI, technical teams have restarted the system. However, it will take time to clear the backlog that has been created due to manual processing since morning. Therefore, minor delays in flights may still persist.
AAI expressed regret
AAI expressed regret for the inconvenience caused to passengers and airlines and said that work is going on rapidly to bring the system back to normal. Passengers are requested to keep in touch with their airlines for latest flight status.
