Delhi Airport Operations Slowly Normalizing After 15-Hour ATC System Glitch
Imagine the air traffic control system at the Delhi airport is like a traffic police officer directing airplanes.
On Friday, this 'officer' had a technical problem with their computer system for over 15 hours.
This meant they had to manually write down instructions for each plane, which is much slower.
Because of this, many flights were delayed, and some were even canceled, making it hard for people to travel.
By Saturday morning, the airport authorities said the system was getting better, and things were slowly returning to normal, though some delays might still happen.
Flight operations at Delhi's Indira Gandhi International Airport (IGIA) are gradually returning to normal.
A 15-hour technical glitch in the air traffic control's Automatic Message Switching System (AMSS) caused significant disruptions on Friday.
The AMSS issue, detected on November 6, led to over 800 flights being delayed and some services canceled.
Air Traffic Controllers had to manually prepare flight plans for over 15 hours due to the system failure.
Airport operator DIAL and the Airports Authority of India (AAI) are working to fully restore systems and minimize passenger inconvenience.
