When would it be appropriate to use "PAN PAN PAN"?

Using "PAN PAN PAN" is designated for urgent situations that do not pose an immediate threat to life or vessel safety, but require assistance or attention. This term is recognized internationally in maritime communication and indicates that the situation is urgent and needs focus, but it doesn't reach the level of a distress signal, which would call for "MAYDAY."

For example, if a vessel has mechanical failure that could lead to danger but isn't immediately life-threatening, a "PAN PAN" call would effectively communicate the need for assistance. It alerts other vessels or authorities to the urgency of the situation while clearly indicating that life is not in imminent danger, allowing them to prioritize their responses accordingly.

In contrast, referring to situations like navigational hazards or general safety information doesn't fit the criteria for a "PAN PAN" call, as these matters may not require immediate assistance but rather routine navigation or communication procedures.
