What is the code designated for aircraft emergencies?

The code designated for aircraft emergencies is 7700. This code is used in the context of air traffic communication to alert air traffic control that an aircraft is experiencing an emergency situation. When a pilot squawks 7700 on their transponder, it signals to air traffic controllers that immediate assistance may be required due to a critical situation on board.

In the realm of air traffic communication, different transponder codes are employed for specific situations: for instance, 7500 indicates unlawful interference or hijacking, while 7600 signifies a radio communication failure. Understanding these codes is vital as they allow pilots to communicate effectively and succinctly with air traffic control in urgent scenarios.
