What is the correct radio call format for a mayday?

• A. Help me, I am stuck, over.
• B. Mayday now—send support, repeat later.
• C. Mayday, Mayday, Mayday—[unit], location if known, situation, need for rescue, over. Then repeat and follow incident command guidance.
• D. I require assistance, please respond.

Answer: (C)

Using a standardized mayday radio call right away signals life-threatening danger and communicates essential details to responders. The proper format starts with the distress call repeated three times, to grab attention even in a noisy channel. Immediately identify your unit and location if known, then describe the situation and the need for rescue, and conclude with over to close the transmission in the proper radiotelephony style. After that, repeat the message as directed by incident command and follow their guidance to ensure a coordinated, rapid response. This approach is critical because it conveys urgency, identifies who is in trouble, where they are, what’s happening, and what is needed, in a concise, unambiguous way. Other options fail to deliver the complete, standardized information or omit key elements like the explicit mayday, unit identification, location, or the rescue requirement, which can delay lifesaving actions.
