If someone says "I have a PAN PAN situation," what should you understand?

When someone states "I have a PAN PAN situation," it indicates that they require assistance due to safety concerns, but they are not in immediate danger or distress. The term "PAN PAN" is a standard aviation and maritime distress call used to signify an urgent situation that requires attention but does not pose a severe threat to life or safety. This communicates to authorities and other personnel that while there is a need for assistance, the situation is not yet critical.

The other choices reflect different levels of urgency and communication, such as being in serious danger or reporting normal operations, which are not conveyed by the term "PAN PAN." Thus, the essence of the term is to alert only for assistance while maintaining a clear distinction from more alarming distress calls like "MAYDAY."
