In what situation would you use a "Pan-Pan" call?

A "Pan-Pan" call is utilized in maritime communication when there is a situation that requires urgent assistance but does not pose an imminent threat to life or vessel safety. This form of distress signal indicates that there is a potential safety issue that needs attention, such as a vessel that has experienced mechanical failure, a situation that could escalate if not addressed promptly, or a request for guidance and support without an immediate life-threatening scenario.

By using a "Pan-Pan" call, the communicator ensures that their message is prioritized by other vessels and authorities, allowing for a swift response while conveying the severity of the situation without raising alarms unnecessarily. This contrasts with emergency situations that would require a "Mayday" call, which is meant for distress situations where there is a danger to life or the vessel is in imminent peril. Therefore, the correct answer reflects the appropriate use of the "Pan-Pan" signal in situations where urgent attention is needed but the situation is not life-threatening.
