What does "Pan Pan" signify in maritime communication?

"Pan Pan" signifies an urgent call in maritime communication, used primarily to indicate a situation that requires assistance but does not constitute a life-threatening emergency. This term is recognized internationally, and when it is communicated, it alerts other vessels and maritime authorities that there is an urgent situation that may need handling, such as a vessel in distress or requiring vital assistance.

The use of "Pan Pan" is essential in ensuring that other vessels are aware of the urgency of the situation, allowing for a coordinated response. This communication is important for the safety and efficiency of maritime operations, as it helps prioritize responses without causing the unnecessary alarm that comes with a distress call, which is signified by "Mayday."

While other choices suggest differing levels of urgency and types of communication, "Pan Pan" is specifically tailored to convey urgency without indicating a grave danger to life or vessel.
