Final answer:
The basic requirements for an Urgency (Pan-Pan) Emergency broadcast include the vessel's exact location, a declaration of urgency, guidance for nearby vessels, and using correct radio frequencies like VHF channel 16 or MF/HF 2182 kHz; a Mayday signal is not part of a Pan-Pan message.
Step-by-step explanation:
The basic requirements for an Urgency (Pan-Pan) Emergency broadcast include:
- Vessel's current location: The precise position of the vessel, often given in latitude and longitude, so that nearby vessels and rescue services can find it quickly.
- Declaration of urgency: Clearly communicating that the situation is urgent but not yet life-threatening, differentiating it from a MAYDAY call.
- Mayday signal: Incorrectly listed here as the MAYDAY signal is used for grave and imminent danger, while Pan-Pan is used for urgent situations. This should not be part of a standard Pan-Pan message.
- Expected actions from nearby vessels: Guidance or requests for assistance, without requiring immediate help that a mayday situation might entail.
Messages are typically broadcast over maritime radio frequencies, and for urgency traffic, the initial call should be made on the VHF (Very High Frequency) international distress frequency of 156.450 MHz (VHF channel 16) or the MF/HF (Medium Frequency/High Frequency) distress frequency 2182 kHz, depending on the equipment and range needed.
