The distress procedure word MAYDAY indicates that a vessel or a person is in grave and immediate danger and that immediate assistance is required. All Mayday voice calls are sent on Channel 16 on high power.

It is the second most important call after the Mayday call. The most common times Pan-Pan calls are made on a boat, are engine or rudder failure.
