“India's systems must align with global benchmarks such as Eurocontrol and the FAA, which emphasise predictive tools, AI-enabled conflict detection, and real-time data sharing,” the Guild had written in a communication sent to the government and aviation authorities in July 2025, accoding to India Today reports.

On Saturday, Union Minister of Civil Aviation, Ram Mohan Naidu Kinjarapu also visited the Air Traffic Control (ATC) Tower at Delhi Airport to review operations after the technical glitch in the ATC messaging system.

The Minister directed officials to conduct a detailed root-cause analysis and enhance system redundancy to make the ATC network more resilient for the future.

"Over the past two days, teams from AAI, ANS, and ECIL worked tirelessly to identify and resolve the issue while ensuring passenger safety through manual coordination. As systems are fully restored now, I have further directed officials to conduct a detailed root-cause analysis and enhance system redundancy to make our ATC network more resilient for the future, " Kinjarapu said in a post on X.

A technical glitch in the Air Traffic Control (ATC) messaging system at Delhi Airport occurred on Friday afternoon. The issue, which continued into Saturday morning, led to delays and cancellations of 46 flights.
