Flight operations were severely affected on Friday after a major technical glitch in the AMSS system at Delhi’s Indira Gandhi International Airport, due to which more than 200 flights were delayed. Earlier it was told that this has affected Mumbai Airport also, however later Mumbai Airport Authority said that advisory was issued to the passengers by mistake.
AMSS failed at Delhi airport
As soon as the AMSS system crashed at Delhi Airport, the air traffic control had to leave the automatic mode and work manually. Due to this, the data of each flight had to be processed manually. Distance calculations of the planes also had to be done manually and coordination had to be done through voice communication, due to which the operation of flights became much slower than usual.
Delay of more than an hour at Delhi airport
At present, there is an average delay of 62 minutes i.e. more than an hour in the departure of flights at Delhi Airport. According to data from Flightradar24, this delay has increased after a technical glitch in the air traffic control system. Airports Authority of India (AAI) has said that its teams are busy fixing the AMSS (Automatic Message Switching System), which supports ATC data. There are approximately 1,500 flight movements daily at Delhi Airport. Under normal conditions, 60-70 flights take off and land per hour. In such a situation, due to automation failure, the backlog of flights increased rapidly and the delay extended for several hours, the effect of which was seen in the entire network.
Mumbai Airport issued clarification
Mumbai Airport (MIAL) said that the advisory issued earlier was issued by mistake and was a human error. The airport clarified that all flight operations here are running completely normal and smoothly.
What is AMSS system?
AMSS is the system that sends flight plans, weather information, and other technical data between ATC and airlines. Once it fails, controllers have to enter all the data manually, which makes operations extremely slow and significantly affects flight time.
AAI issued advisory
Airport Authority of India issued a statement saying that due to AMSS malfunction at Delhi Airport, flight operations are getting delayed and the controllers are processing all the plans manually. Technical teams are continuously working on restoring the system. Passengers have been advised to stay in touch with their airlines and keep checking updated schedules.
Advisory issued for the convenience of passengers
Authorities have requested passengers to keep checking flight information from their respective airlines, be prepared for possible delays and follow instructions given at the airport. The situation is being monitored in both Delhi and Mumbai so that the system can be normalized as soon as possible.
