Pan Pan


An urgent message used on a radio regarding the safety of people or property. A mayday call is used when there is an immediate threat to life or property. A pan pan situation may develop into a mayday situation. Pan pan and mayday messages have priority on radio channels and should not be interrupted. In the case of a less urgent safety message, the securite signal is used.
