Pan-pan

The radiotelephony message PAN-PAN is the international standard urgency signal that someone aboard a boat, ship, aircraft, or other vehicle uses to declare that they need help and that the situation is urgent,[1][2][3] but for the time being, does not pose an immediate danger to anyone's life or to the vessel itself.[4] This is referred to as a state of "urgency". This is distinct from a mayday call (distress signal), which means that there is imminent danger to life or to the continued viability of the vessel itself.[5] Radioing "pan-pan" informs potential rescuers (including emergency services and other craft in the area) that an urgent problem exists, whereas "mayday" calls on them to drop all other activities and immediately begin a rescue.

The exact representation of PAN in Morse code is the urgency signal XXX, which was first defined by the International Radiotelegraph Convention of 1927.[6]
