What does Mayday mean in aviation? Where did it come from?

Mayday is a type of distress signal that is used for emergency distress.

Mayday originated from the French word m'Aidez, said"Help me, help"。Mayday is spelled this way only because the pronunciation of the word is close to that of French. In terms of the number of syllables, Mayday has two tones mei-dei, and SOS has five tones a-hiss-ou-a-hiss, and the most concise way is to call for help.

Mayday is an international radio distress signal. The word "mayday" was originally the French "m" for "save me."'Aider" (not used alone in standard French, usually Venez M'Aider or Aidez-Moi) is pronounced "Mayday" in English. A mayday call over the radio refers to the encounter with a real-time danger situation that threatens life.

Mayday must be called three times in a row ("mayday, mayday, mayday") to avoid mishearing, being overshadowed by noise, or being confused with other communications. Usually ships or planes will call for help with a Mayday signal; Police and firefighters in some areas also called for help from their colleagues.

Mayday is an international radio distress signal. mayday** in French m'Aider is the French word for "help me", which is written in English and becomes Mayday.

Origin: The use of Mayday as a distress signal originated in 1923 by an Englishman named Federick Stanley Mockford. At that time, he was working as a senior radio student at an airport in London, England.

The airport asked him to come up with a simple and easy-to-understand word for all pilots and ground staff to call for help in case of emergency. Since most of the flights were to and from Paris at that time, it was taken from French. In French, it means m for help'The word aider was proposed, and this is how the homonym for the English word "mayday" came from.

Mayday means help me, and is generally used to say in case of danger. Mayday is the highest distress signal in the aviation industry, and the purpose of saying this is to let the air traffic control personnel prioritize management and tell the air traffic control aircraft that there is an emergency. If you talk nonsense, mayday will be punished accordingly.
