Mayday: An International Distress Signal24

Mayday, pronounced [ˈmeɪdeɪ] in English and [] in French, is an international distress signal used to indicate a life-threatening emergency. It is transmitted via radio or other communication devices, and is recognized by all maritime, aviation, and land-based emergency services.

The term "mayday" was first adopted by the International Radio Regulations in 1927. It was chosen because it is easy to pronounce and understand in multiple languages, and its three syllables create a distinctive sound that can be easily distinguished from other radio traffic.

To issue a mayday call, the following procedure should be followed:
Establish contact with the appropriate rescue coordination center (RCC) by transmitting the following information:

Your location (latitude and longitude)
The nature of your emergency
The number of people on board
Any other relevant information, such as the condition of the vessel or aircraft


Transmit the distress message three times, using the following format:

Mayday
Mayday
Mayday
Your call sign
Your location
The nature of your emergency


Continue transmitting the distress message at regular intervals until you are contacted by the RCC or another rescue unit.

It is important to note that mayday calls should only be used in life-threatening emergencies. False or malicious mayday calls can interfere with legitimate distress signals and put lives at risk.

In addition to its use as an international distress signal, mayday is also used in some countries as a general emergency call for assistance. For example, in the United States, the Federal Communications Commission (FCC) allows the use of mayday to report any situation where life or property is in danger.

Mayday is a vital distress signal that has saved countless lives around the world. By understanding its proper use, you can help to ensure that you and your loved ones are safe in the event of an emergency.
