There was chaos at Indira Gandhi International Airport (IGI Airport) in the country’s capital Delhi on Friday (November 7) when a sudden technical glitch in the air navigation system affected the operations of the entire airport. Due to this disturbance at IGI, which is counted among the busiest airports in the world, about 800 flights were delayed and thousands of passengers had to wait at the terminal for hours.
According to sources, this technical flaw in the Air Traffic Control (ATC) system was so serious that both flight landing and takeoff were affected for some time. Many planes were kept in holding patterns in the air, while some had to be diverted to nearby airports. The problem was resolved at around 9 pm, after which flight movements gradually started becoming normal. It is a matter of relief that there was no major accident with any aircraft.
Passengers expressed displeasure
Expressing their displeasure, the passengers said that they were not informed about the situation for several hours. At the same time, passengers of many domestic and international flights were stopped at the gate as runway operations were temporarily stopped.
Where did the problem come from?
The Airport Authority and DGCA immediately deployed technical teams to handle the situation. The failure was related to the navigation data server, causing disruption in communications and navigation systems. During this time the airport staff tried to solve the problems of the passengers.
Advisory issued at around 11:55 pm
In an advisory issued at around 11:55 pm, Delhi Airport Management said, “All flight operations have now become normal. Passengers can travel without any worries.”
