Which radio call signals a very urgent safety message that is less serious than a MAYDAY?

PAN PAN, said three times.

  1. PAN PAN ✔
  2. SECURITE
  3. ROGER

Why: PAN PAN signals a very urgent message about the safety of a vessel or person. It outranks everything except a MAYDAY. Save MAYDAY for grave and imminent danger.

Huh, didn't know that: SECURITE, also said three times, warns of a navigation safety or weather message.
