The rules are laid down for interception of civil aircraft by military aircraft, to maintain safety and security within the national borders of the intercepting aircraft. The reasons are various but most commonly:

  • Civil aircraft is flying without a flight plan or notifying any air traffic control of the flight.
  • Crossing borders without prior permission.
  • Complete loss of radio communication and aircraft can’t be identified.

The figures attached show that when the military aircraft changes suddenly the heading 90o or more and pull-up of the aircraft without crossing the track of the intercepted aircraft it means you may continue your flight.
