India’s busiest airport, Delhi’s Indira Gandhi International Airport (IGIA), faced major flight delays on Friday morning thanks to a sudden technical failure! The Automatic Message Switching System (AMSS), a crucial tool that supports Air Traffic Control (ATC) by sending vital flight data, broke down. This glitch threw the whole northern sky into a mess, affecting big names like IndiGo, Air India, and SpiceJet. Here’s the scoop: AMSS helps ATC communicate quickly with planes, telling them where to go, when to take off, and much more. When this system stopped working, controllers had to juggle flights manually — like trying to manage a busy market without any tools! This delay caused traffic jams in the skies, slowing flights down big time. Delhi airport officials shared an update at 6:36 AM saying the system was "gradually improving" and flights were "returning to normal." But passengers were warned to double-check their flight timings before heading out, since delays were still happening. IndiGo Airlines, the country’s largest low-cost carrier, was hit hard but stayed on top. Their social media updates said, "Airport operator and ATC teams are working on a priority to fully restore systems and stabilise operations. The situation is expected to be normalised over the next few hours. During this period, some departure and arrival timings may continue to be adjusted." They advised travellers to check online at bit.ly/2EjJGGT and keep some extra time handy. After hours of hard work, IndiGo announced the AMSS glitch was fixed, praising airport and ATC teams for their speedy action. Their message: "We are pleased to share that the temporary AMSS system outage affecting Air Traffic Control has now been resolved, and normal operations are being progressively restored at Delhi Airport and other impacted airports in the northern region." They did warn, however, that some delays and crowding might still happen as things settle down. How big was the chaos? Over 100 flights were delayed, both domestic and international. Airlines including Air India and SpiceJet also told passengers to expect wait times and check their flight status often. Why is ATC so important? Think of it as the city's traffic police but for the sky. It makes sure planes take off, fly, and land safely without crashing into each other. Systems like AMSS help ATC talk to aircraft quickly and share important info like weather and routes. By Friday afternoon, things started clearing up. Airlines worked hard to catch up and smooth out the mess. Passengers are still urged to stay connected with their airlines and plan extra travel time just in case. The air traffic storm may be calming, but today’s events remind us how much we depend on tech magic to keep our skies safe and sound.
