Mayday

The international radiotelephony distress signal, spoken three times ("Mayday, Mayday, Mayday") to declare a life-threatening emergency requiring immediate assistance. A Mayday call takes priority over all other radio communications. After the initial call, the pilot should state their callsign, position, nature of the emergency, intentions, souls on board, and fuel remaining. Squawk 7700 should be set on the transponder simultaneously.
