A technical glitch in the Air Traffic Control (ATC) messaging system at Delhi Airport occurred on the afternoon of November 6, 2025. The issue, which continued into the morning of November 7, led to delays and cancellations of 46 flights.

From the onset, teams from Airports Authority of India (AAI), Air Navigation Services (ANS), and Electronics Corporation of India Limited (ECIL) worked round the clock to identify and rectify the issue. ECIL promptly deputed additional manpower to assist in the restoration process. During this period, ATC staff efficiently managed flight operations manually to ensure passenger safety and minimize inconvenience.

Late in the night on November 7, Union Civil Aviation Minister Shri Rammohan Naidu visited the Delhi ANS Centre near the airport at 10 PM to review the situation. He was accompanied by Secretary (MoCA) Shri Samir Kumar Sinha, Chairman (AAI) Shri Vipin Kumar, and senior officials.

The Minister directed the ECIL CMD to deploy additional technical manpower to expedite the restoration efforts. To minimize passenger inconvenience, the Minister also directed that more ATC staff be deployed at Delhi Airport to support manual operations and ensure smooth handling of air traffic during the system downtime.

Owing to the coordinated efforts of ECIL engineers, ATC personnel, and the Ministry’s proactive monitoring, the system was fully restored to automatic mode by afternoon of November 8 (today). There were no flight cancellations today owing to the issue.

Later in the evening today, Shri Rammohan Naidu visited the ATC Tower to review normalised operations and appreciated the commitment of the teams that worked overnight to resolve the issue.

Further, the Minister has directed that a detailed root-cause analysis be undertaken to prevent recurrence of such glitches in the future. He also instructed officials to plan for more system advancements, including additional or fallback servers to strengthen ATC operations.
