In the Latest News from India’s aviation sector, air traffic controllers at Delhi’s Indira Gandhi International Airport (IGI) have claimed that last Friday’s system failure could have been avoided. The Breaking News follows massive flight delays and cancellations that affected more than 800 flights, both domestic and international.
According to the Air Traffic Controllers Guild (ATC Guild) of India, they had already warned the Airports Authority of India (AAI) about possible technical risks months before the glitch happened. The guild said it had written to the AAI in July 2025, urging urgent upgrades to outdated automation systems used for managing flight operations.
Warnings Ignored Since July
- The ATC Guild revealed that they had highlighted the problem in a written report to AAI and Members of Parliament back in July 2025.
- This letter came just after the tragic Air India Dreamliner crash in Ahmedabad that killed 260 people.
- The controllers warned that without timely upgrades, such technical issues could create serious safety risks.
- They also suggested that India’s system should match the international standards followed by Eurocontrol in Europe and the Federal Aviation Administration (FAA) in the United States.
The controllers argued that these global systems use Artificial Intelligence (AI) and real-time data sharing to prevent potential technical failures. They stressed that adopting such technologies could make Indian airspace safer and more efficient.
The Day of the Breakdown
The Breaking News incident took place when the Automatic Message Switching System (AMSS) — a crucial part of air traffic operations — malfunctioned. This system manages all flight plan messages and real-time communication between pilots and ground control.
- The failure caused major confusion, leading to massive flight delays.
- Around 800 flights were either delayed or cancelled.
- The disruption didn’t just affect Delhi but had a ripple effect on several international routes.
Airlines struggled to coordinate schedules, and passengers were left stranded for hours at the country’s busiest airport. Officials later said the AMSS glitch had disturbed normal air traffic communication, leading to a temporary suspension of several services.
Operations Back to Normal
By Friday afternoon, Delhi International Airport Limited (DIAL) confirmed that flight operations had returned to normal. In an update posted on X (formerly Twitter), DIAL said:
“Airline operations at Delhi Airport are returning to normal. All authorities are working hard to minimise inconvenience.”
However, passengers were advised to stay in touch with their airlines for Daily news highlights and real-time flight updates.
Need for Modernisation
The ATC Guild once again called for modern technology upgrades to prevent future incidents like this. They said India’s aviation automation system must:
- Meet international standards for data security and performance.
- Include AI-driven tools to detect system threats in advance.
- Enable smooth data exchange between airports for better coordination.
- Receive regular safety audits to ensure reliability.
The Guild added that several warnings have been issued to the AAI over the years, but little action has been taken. They described this as a “serious security lapse” that could have long-term implications if not resolved.
The Bigger Picture
Delhi’s Indira Gandhi International Airport is India’s busiest aviation hub, handling more than 1,500 flights per day across four runways. A disruption of this scale shows how critical robust automation is to national air safety.
The AAI later issued a statement confirming that the technical issue had been resolved and that new preventive steps were being planned to avoid similar events in the future.
This Latest News development has reignited debates about India’s aviation infrastructure and whether the government is investing enough in technology and safety standards to match global benchmarks.
