Radio in emergencies: Mayday, pan-pan, safety instructions
Understanding emergency radio communication protocols—including Mayday, Pan-Pan and relevant safety instructions—is crucial for all pilots and aviation personnel. Clear and effective voice radio calls during emergencies can dramatically improve the response time and coordination with air traffic control (ATC), ultimately ensuring the safety of everyone involved. 🚨✈️
What Is a Mayday Call and When Should It Be Used?
A Mayday call is the highest priority radio communication in aviation emergencies, used when an aircraft and its occupants are in imminent danger and require immediate assistance. Examples include engine failure, fire onboard, structural failures, or imminent forced landings. 🚒
Mayday Transmission Format: When transmitting a Mayday call via radio, clearly and calmly state the following information:
- The word "Mayday" repeated three times.
- Your aircraft identifier (callsign).
- The nature of the emergency.
- Your intentions and assistance required.
- Your current position, altitude, and heading.
What Is a Pan-Pan Call and How Does It Differ from Mayday?
A Pan-Pan call signals urgency rather than immediate, life-threatening danger. It is used when there is an issue that requires prompt attention, but the flight's safety is not immediately at risk. Examples include medical emergencies onboard or minor technical issues affecting flight safety. 🩺🛠️
Pan-Pan Transmission Format: To transmit a Pan-Pan call, pilots must communicate clearly by providing:
- The words "Pan-Pan" repeated three times.
- Aircraft callsign.
- Nature of urgency.
- Level of assistance required.
- Position, altitude, and heading details.
