What is the squawk code for an emergency situation?

The squawk code for an emergency situation is 7700. This code is universally recognized by air traffic control and is used by pilots to indicate a general emergency. When a pilot sets their transponder to squawk 7700, it alerts air traffic controllers that the aircraft is experiencing an emergency and may require immediate assistance or priority handling. The distinction of this specific code helps ensure that emergency situations are quickly identified and escalated for appropriate response from air traffic control.

The other codes have specific, separate meanings: for instance, 7500 indicates a hijacking, 7600 signifies loss of communication, and 7400 does not have a standard aviation-related significance. Understanding these codes is crucial for both pilots and air traffic controllers to effectively communicate during critical situations.
