Which VHF call signifies urgent information but is not life-threatening?

The term that signifies urgent information but is not life-threatening is "Pan-pan." This specific call is used in maritime communication to indicate a situation that requires attention but does not involve imminent danger to life or vessel. It serves as a way for mariners to convey important information regarding safety risks, such as a vessel that is experiencing a mechanical issue or a navigational hazard, without signaling a crisis.

Understanding this terminology is crucial for effective communication on the water, as it helps prioritize response efforts for emergencies while ensuring that urgent but non-life-threatening situations receive the attention they need. "Securite" is a notification that indicates safety messages, while "Mayday" clearly denotes a life-threatening emergency. "Attention" is not a standardized maritime distress call and therefore does not convey the same urgency or context.
