What is the emergency transponder code for general emergencies?

The emergency transponder code for general emergencies is 7700. This code is universally recognized and signifies that an aircraft is experiencing a general emergency and requires immediate assistance. When a pilot sets the transponder to 7700, air traffic control and nearby aircraft are alerted to the emergency situation, enabling a prompt response to assist the distressed aircraft.

Understanding the significance of this code is crucial for pilots, as it facilitates quicker communication of an emergency situation to air traffic controllers, who can then prioritize their assistance. This code differs from others: for example, 7500 indicates a hijacking, and 7600 signals a radio communication failure. Thus, setting the transponder to 7700 is a critical step for any pilot facing an emergency, ensuring that they receive the necessary help as swiftly as possible.
