What squawk code is used for emergencies in general aviation?

The squawk code used for emergencies in general aviation is 7700. This code is universally recognized within the air traffic control system as the signal for an emergency situation, alerting both air traffic controllers and other aircraft that the pilot requires immediate assistance. When a pilot selects this code on their transponder, it indicates that they are facing an in-flight emergency, which could range from technical failures to health issues affecting the crew or passengers.

When this code is activated, air traffic control prioritizes the aircraft's situation, providing necessary support and guidance, and facilitates a safe landing. This clearly delineates the emergency level for both the pilots and controllers involved, ensuring swift action is taken.

The other codes serve different purposes: 1200 is used for VFR (Visual Flight Rules) operations, 1400 does not pertain to any widely recognized function, and 7600 is specifically designated for communications failure.
