PAN-PAN

The international urgency signal "PAN-PAN" derives from the French word *panne* (breakdown) and is utilized in maritime VHF radio communications to signal urgent situations involving the safety of a vessel or individual. Unlike the distress signal MAYDAY, which is reserved for grave and imminent danger threatening human life or the loss of the vessel, PAN-PAN denotes an urgent condition where immediate life-threatening danger is absent. Typical scenarios include engine loss in open waters without an imminent drift toward lee shores, steering failure, or an urgent medical consultation request (PAN-PAN MEDICO).

Under GMDSS standards, the call is transmitted on VHF Channel 16 (frequency 156.8 MHz) at standard high power (25 W). The proper format requires repeating "PAN-PAN" three times, followed by the target addressee, vessel name, call sign, MMSI number, precise position, nature of the urgency, and requested assistance. This nautical terminology must be distinguished from homonyms such as the Pan American Games (Pan Am Games multi-sport event noted in Wikipedia records).

In cases of mechanical malfunction, a skipper might broadcast a PAN-PAN to secure a tow toward a protected yacht marina. Monitoring reliable weather forecast sites further helps crews anticipate severe conditions before an urgency call becomes necessary.
