Overview
- Pilots and controllers reported severe signal deception within roughly 60 nautical miles of Delhi, with instruments showing wrong positions and false terrain alerts.
- The interference disrupted RNP procedures while the main ILS is withdrawn for upgrades, causing congestion, delays and seven diversions to Jaipur on one night.
- Air traffic controllers provided direct heading and altitude guidance to crews, and ATIS messages advised caution and use of alternate navigation sources.
- The civil aviation regulator confirmed it is collecting data and examining the events, with a potential handoff to security agencies if warranted and continued work under ICAO safety guidance.
- Experts stressed that spoofing manipulates signals unlike jamming and warned that sustained interference over the National Capital Region could carry national security implications.
