Flying thousands of feet above the ground demands clear and instant communication. When emergencies happen, every second counts. That’s when the Mayday call becomes essential. But what is a Mayday call, and why do pilots use it?
This guide breaks down the Mayday call meaning, explains when to use it, compares it with other aviation distress signals, and shows what happens next. Whether you’re a frequent traveler or new to aviation, you’ll find this guide easy to follow.
1. What Is a Mayday Call?

A Mayday call is an emergency signal. Pilots use it when they encounter a life-threatening situation during a flight.
The call comes from the French phrase “m’aidez,” meaning “help me.” Aviation adopted the word in the 1920s because it was short, clear, and easy to understand over radio static.
Pilots only use a Mayday signal in aviation during the most serious emergencies, such as:
- Engine failure
- Onboard fire
- Structural damage
- Imminent crash landing
- Critical medical emergencies
When pilots call Mayday, air traffic controllers immediately prioritize that aircraft and clear the surrounding airspace.
2. How Do Pilots Make a Mayday Call?
Pilots make a Mayday call over the aircraft’s radio using a standard format:
“Mayday, Mayday, Mayday, this is [Aircraft Call Sign]. We are experiencing [type of emergency]. Our position is [location]. We are [intentions or requests].”
For example:
“Mayday, Mayday, Mayday, this is Delta 123. Engine failure. We are 20 miles northeast of Atlanta at 10,000 feet. Requesting immediate return to ATL.”
Pilots repeat “Mayday” three times to ensure the call stands out. This standard format keeps in-flight emergency communication clear and quick.
After hearing the call, air traffic controllers take over. They clear the route, provide guidance, and coordinate emergency services if needed.
3. Mayday vs. Pan-Pan: What’s the Difference?
Not every emergency requires a Mayday call. Pilots use Pan-Pan when the situation is urgent but not immediately life-threatening.
The term Pan-Pan comes from the French word “panne” (meaning “breakdown”). It alerts controllers that something’s wrong, but there’s no immediate danger.
Here’s a quick comparison:
Signal | Meaning | Severity | Examples |
Mayday | Life-threatening emergency | High | Fire, engine failure, loss of control |
Pan-Pan | Urgent but not critical | Medium | Minor system failure, sick passenger |
So, why do pilots say Mayday? Because they need help—now. This signal triggers an immediate response, while Pan-Pan requests attention without urgent action.
4. Other Aviation Emergency Signals

Pilots also use several other tools to communicate distress:
Squawk Codes
Pilots enter special transponder codes to report emergencies silently:
- 7700 – General emergency
- 7600 – Radio communication failure
- 7500 – Hijacking
These codes instantly alert air traffic control, even without a radio message.
Emergency Locator Transmitters (ELTs)
ELTs send out location signals after a crash or when triggered manually. Rescue teams use them to find the aircraft quickly.
Light and Hand Signals
Pilots and ground staff use standard hand gestures or light signals if radios fail. These simple tools form part of basic aviation distress signals training.
5. What Happens After a Mayday Call?
Once pilots make an emergency call, air traffic controllers act immediately:
- They prioritize the aircraft.
- They clear other planes from the area.
- They guide the pilot to the safest possible landing location.
- They notify emergency responders on the ground.
Controllers may ask nearby pilots to assist or observe if they hear the call.
Pilots, controllers, and ground teams work together to protect the people on board.
6. Real-Life Examples of Mayday Calls
In 2009, U.S. Airways Flight 1549 struck a flock of birds after takeoff and lost both engines. The pilot issued a Mayday call and safely landed the plane on the Hudson River. All 155 people survived. That flight became known as the “Miracle on the Hudson.”
Another example is British Airways Flight 38 in 2008. The engines lost power just before landing. The pilot made a Mayday call and safely brought the plane down on the runway. These cases show how powerful and effective in-flight emergency communication can be in the hands of trained professionals.
7. Common Myths and Misunderstandings
Myth 1: A Mayday call means the plane will crash.
That’s not true. Pilots issue a Mayday to prevent disaster, not to announce it.
Myth 2: Pilots casually say Mayday.
No. They follow strict rules and only say it during the most serious emergencies.
Myth 3: Passengers always hear Mayday calls.
Most of the time, passengers don’t hear these calls. They take place between the cockpit and air traffic control.
8. Why Should Passengers Understand Mayday Calls?

Knowing about aviation distress signals can reduce fear and build confidence in air travel. Here’s why:
- Pilots train regularly to handle emergencies.
- Air traffic controllers provide immediate support.
- The aviation system includes backups at every level.
You don’t need to be an expert, but understanding the basics helps you stay calm and trust the professionals during any unexpected situation.
Takeaway
The Mayday signal in aviation isn’t just a dramatic phrase; it’s a lifesaving tool. When a pilot makes a Mayday call, the entire aviation network responds instantly. Air traffic control clears the way. Emergency teams prepare to assist. Every move centers on keeping people safe.
So the next time you fly, take comfort in knowing that the emergency call used by pilots exists for your protection.
Frequently Asked Questions
What is a Mayday call in aviation?
A Mayday call is an emergency distress signal used by pilots to alert air traffic control that the aircraft is experiencing a life-threatening situation. It triggers an immediate response and top priority handling.
Why do pilots say “Mayday” three times?
Pilots repeat “Mayday” three times to ensure the message stands out from regular communication. This repetition helps prevent misunderstandings and ensures clear urgency, especially over noisy radio channels.
What’s the difference between Mayday and Pan-Pan?
“Mayday” signals a life-threatening emergency (like engine failure or fire), while “Pan-Pan” indicates an urgent but non-critical situation (like a sick passenger or minor equipment issue).
What happens after a pilot declares a Mayday?
Air traffic controllers ensure aircraft safety by clearing the surrounding airspace and providing pilots safe routes and instructions. In emergencies, they alert the appropriate response teams for coordinated action.
Is it common for planes to issue a Mayday call?
No, it’s relatively rare. Pilots only declare a Mayday when the situation is serious. Most flights never experience emergencies that require it.
Can passengers hear a Mayday call during a flight?
Usually not. Mayday calls happen between pilots and air traffic control via radio. Passengers may only know about it if the flight crew decides to make an onboard announcement.
Is Mayday used in other industries?
Yes. Ships and boats also use the Mayday call in maritime emergencies. It’s an internationally recognized distress signal in both aviation and maritime sectors.
