Where Does ‘Mayday’ Come From?
The word ‘Mayday’ comes from the French “m’aider”, meaning “help me”. It was adopted in the 1920s so pilots and sailors could ask for urgent help over the radio.

How is a Mayday Call Made?
Pilots repeat the word “Mayday” three times on the radio: “Mayday, Mayday, Mayday”. This makes sure the message is clear and not confused with other words, even in noisy situations.

When is Mayday Used on Boeing 787?
On a Boeing 787, pilots use Mayday only for serious emergencies. These can include engine failure, fire, loss of cabin pressure, or if the aircraft must make an emergency landing.

What Happens After a Mayday Call?
Once a Mayday is declared, air traffic controllers give the aircraft top priority. Emergency services get ready, and other planes are moved out of the way to help the flight land safely.

Mayday vs. Pan-Pan
‘Mayday’ is used for life-threatening emergencies. ‘Pan-Pan’ is another call for urgent help, but not life-threatening. Pilots are trained to know the difference and use the right call.
