Why do we say certain things *three times*, e.g., “Mayday. Mayday. Mayday”?
Repetition is a key characteristic of communication in the control tower, cockpit, and control room. Some phrases, like "Mayday" get repeated. The speaker says the same thing three times.
Why three times?
Is there research suggesting three is the most effective number, or is there a historical reason for the convention?

It sounds like you're asking why three, rather than two or four. In other words, you're not just asking "why do we say it three times"; you're asking "why is three the number of times that we say it". Is that right?

Yep, the critical commands are repeated 3 times. This insures there is ABSOLUTELY zero doubt in anyone's mind (especially on a big crew airplane) what needs to be done in a critical situation. It also standardizes these criticalities across different aircraft and aircrew cultures. "Bail out, bail out, bail out" "Eject, eject, eject" "Abort abort abort." "Pan, pan, pan." I was 27 years a USAF pilot, and this is how the training has worked for over 50 years. I only saw these terms used 2-3 times, but it certainly gets your attention and amps up the sense of urgency. A little history: back in the day of very poor radio communications, it was necessary to repeat to "get someone's attention" or in the event a single "mayday" didn't come across when the transmit button was pressed.

Need clarification. Does emergency "pan" only mentioned 3 times? I heard a senior commercial pilot said that it must be mentioned six times as it only 1 syllable: "Pan-pan, pan-pan, pan-pan".

There are no instances in normal conversation where the same word is repeated three times consecutively. In order to prevent a critical command or order from being issued or heard accidentally, a command is given three times in order to verify that it is being given intentionally.

It sounds like you're asking why three, rather than two or four. In other words, you're not just asking "why do we say it three times"; you're asking "why is three the number of times that we say it". Is that right?
