Listening watch

For the entire period from which you taxi a VHF radio-equipped aircraft onto  the aerodrome’s manoeuvring area (see page 1.25) until the aircraft is brought  to a complete stop at the point of termination of the flight, you must maintain  a ‘listening watch’ using the aircraft’s VHF radio (CAR 243).


Furthermore, whenever you are flying a VHF radio-equipped aircraft in the vicinity  of a non-controlled aerodrome, you must make a broadcast whenever it is reasonably necessary to avoid a collision or the risk of a collision with another aircraft (CAR 166C).
