What is a Mayday Call? Understanding the Universal Emergency Signal
Share
A Mayday call is a critical emergency signal used in voice communication to indicate a grave and immediate danger—such as a plane crash, ship sinking, or a serious medical emergency on board. It alerts nearby authorities and fellow operators that urgent help is needed.
The term “Mayday” comes from the French phrase “m’aidez,” which means “help me.” It was introduced in the 1920s by a senior radio officer at London’s Croydon Airport, who needed a distress term that was easy for both English and French speakers to understand. Since then, it has become an internationally accepted distress call.
🔈 How is it used?
When making a Mayday call, the word “Mayday” is repeated three times to ensure clarity and priority. For example:
“Mayday, Mayday, Mayday — This is Delta 217 — Engine fire — Request emergency landing at nearest airport.”
This repetition helps distinguish the message from normal radio chatter and prevents misunderstandings, especially in noisy or poor signal conditions.
The person making the call then follows up with essential details such as:
- Name and type of vessel or aircraft
- Nature of the emergency
- Location (coordinates or relative position)
- Number of people on board
- Any immediate assistance needed
🚨 When should it be used?
A Mayday call is reserved for life-threatening situations, such as:
- Aircraft or ship mechanical failure
- Fire or explosion
- Man overboard
- Collision
- Medical emergencies needing immediate attention
Misuse of the Mayday call is taken very seriously and may lead to legal penalties, as false distress calls can delay help to real emergencies.
⚠️ What’s the difference between Mayday and Pan-Pan?
While “Mayday” signals a critical emergency, “Pan-Pan” (from French “panne,” meaning “breakdown”) is used for urgent but non-life-threatening issues. For instance, an engine problem that doesn’t immediately endanger the aircraft or ship may call for a Pan-Pan, not a Mayday.
✈️🌊 Final Word:
The Mayday call is a simple but powerful tool that saves lives by ensuring quick response in emergencies. Knowing when and how to use it can make the difference between disaster and survival—both in the sky and at sea.
