Delhi Flights Face Fake Navigation Signals

Several aircraft approaching Delhi's Indira Gandhi International Airport have encountered deceptive navigation signals, a concern acknowledged by the Civil Aviation Minister. Pilots reported these issues when using satellite-based guidance for Runway 10, reverting to backup procedures upon detecting discrepancies. This problem is not isolated to Delhi, with similar Global Navigation Satellite System (GNSS) interference incidents recorded at Kolkata, Amritsar, Mumbai, Hyderabad, Bengaluru, and Chennai since late 2023.

The broader aviation sector is increasingly vulnerable to digital threats, including widespread ransomware and cyberattacks. In response, the Airports Authority of India is enhancing its cyber-defense systems, adhering to national security guidelines. Protecting aviation networks is an ongoing endeavor, necessitating continuous upgrades to counter emerging threats.
