Distress, urgency and calls

All emergency distress calls - VHF channel 16 or phone *500

MAYDAY: use if a vessel, aircraft or person is in grave and imminent danger and requires immediate assistance.

PAN PAN: use to indicate that a vessel has a very urgent message to transmit about its safety, such as loss of steering.

Note: when MAYDAY is not warranted but urgency is required for the safety of a vessel or person, PAN PAN should be used. Calls and messages must be cancelled if assistance is no longer required or when the incident is over.
