What is the code for a hijacking emergency squawk?

The code for a hijacking emergency squawk is 7500. This specific transponder code is used by pilots to alert air traffic control that they are being hijacked or are experiencing unlawful interference. The significance of this code lies in its ability to communicate an urgent and life-threatening situation without the need for verbal communication, which may not be possible in a hijacking scenario.

When 7500 is squawked, it signals to air traffic controllers that immediate attention is required and that the aircraft may be in danger. This allows for coordinated responses from law enforcement agencies and enhances the safety measures taken in the airspace.

The other codes serve different purposes: 7600 indicates a loss of communication, while 7700 signifies a general emergency, which could cover various situations but does not specifically signal hijacking. The code 1400 is not associated with any standard emergency situation related to aviation. Thus, 7500 is crucial for identifying and handling hijackings effectively.
