Which item is NOT explicitly listed as required in a MAYDAY transmission?

• A. Estimated Time of Arrival (ETA).
• B. Location.
• C. Unit ID.
• D. Name/Designation.

Answer: (A)

In a Mayday, the priority is to get rescuers to the caller quickly by transmitting essential, immediate information: who is in distress (unit identification), where they are (location), and what the emergency is (nature of the problem). Estimated Time of Arrival is not explicitly required in the Mayday message; it’s information more relevant to overall incident planning and coordination and is typically communicated separately as responders organize, not as part of the initial distress call. You may, depending on the department, also share a name or designation for accountability, but the core distress transmission emphasizes identifying the unit and the exact location and describing the emergency so responders can act immediately.
