Authorities are examining ways to strengthen air traffic control (ATC) systems at Delhi's Indira Gandhi International Airport following a technical snag that disrupted operations and delayed over 800 flights. Civil Aviation Minister K Rammohan Naidu confirmed a wider review of processes and technology is underway, with a focus on enhancing air navigation systems and integrating future technologies. The investigation into the Automatic Message Switching System (AMSS) failure is ongoing, and a detailed assessment is being conducted to find the root cause. The Airports Authority of India (AAI) manages these critical functions, and efforts are being made to reinforce operations with backup systems, ensuring normal flight movements continue.
