An urgency message should contain as many of the elements detailed in the “Aircraft in distress” topic as are required by the circumstances. The call should be made on the frequency in use at the time, and the station addressed will normally be that station communicating with the aircraft, or the station in whose area of responsibility the aircraft is operating. All other stations should take care not to interfere with the transmission of urgency traffic.
