What does it mean when a woman says mayday?

Mayday is an internationally accepted radio distress signal. Mayday comes from the French M'aider, which is the verb for "help me" in French. When written together in English, it becomes Mayday.

1. Mayday’s distress call was sent via radio call. Mayday signals sent by aircraft or ships on any channel can be understood. Aviation uses 121.5 MHz and 243.0 MHz; maritime rescue uses the medium frequency 2182 kHz and maritime very high frequency (VHF) channel 16.

2. Mayday is a call for help signal, which means "help me, help me." It is very suitable for long-distance radio transmission with large noise. Because its sound is easy to identify, it is easier to "stand out".

The use of Mayday as a distress signal originated from an Englishman named Frederick Stanley Mockford in 1923. At the 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 an emergency. Because at that time most flights were to and from Paris, it was taken from French. The French word m'aider, which means asking for help, was proposed, and the homophonic English word "Mayday" came from this.
