What is the emergency squawk code for radio failure?

In aviation, squawk codes are assigned to transponders to convey specific information to air traffic control. The emergency squawk code for radio failure is 7600. When a pilot is experiencing communication difficulties and cannot establish or maintain radio contact with air traffic control, this code is used to alert controllers of the situation.

Using this code, pilots can still be tracked by radar, and it indicates to controllers that they may need to take special measures due to the loss of radio communication. The choice of 7600 is significant because it is widely recognized among pilots and air traffic controllers as a standard indication of radio failure, allowing for coordinated responses to ensure safety.

The other codes mentioned correspond to different scenarios; for instance, 7500 indicates a hijacking, while 7700 signifies a general emergency, and 1200 is used for VFR (Visual Flight Rules) operations. Understanding these codes is crucial for maintaining safe and efficient air traffic management.
