After declaring a state of urgency to ATC,on what frequency must the pilot normally maintain listening watch?
  • A
    The international distress frequency.
  • B
    The frequency in use at the time, unless advised by the air traffic controller.
  • C
    Guard frequency.
  • D
    Company frequency.

A distress situation is by definition a condition of being threatened by serious and/or imminent danger and of requiring immediate assistance. A distress situation needs immediate assistance and this is the difference between distress and urgency (urgency does not require immediate assistance).

  • If a pilot of an aircraft encounters an emergency, this situation shall be indicated by a radio call starting with the phrase "MAYDAY" spoken three times. In a distress situation, the pilots shall transmit the distress call on the air-ground frequency currently in use.

Urgency is defined as a condition concerning the safety of an aircraft or other vehicle, or of some person on board or within sight, but which does not require immediate assistance.

  • The signal sent by radiotelephony consisting of the spoken words "PAN PAN, PAN PAN, PAN PAN" ("PAN PAN" spoken three times). The station addressed will normally be that station communicating with the aircraft or in whose area of responsibility the aircraft is flying.
