What transponder code is assigned for a hijack situation?

In a hijacking situation, the transponder code that is assigned is 7500. This code is specifically designated to alert air traffic control (ATC) of a potential hijack incident without the need for verbal communication from the pilot, which may not be possible in such situations. When a pilot sets the transponder to 7500, it immediately sends an alert to ATC and other aircraft in the vicinity that the flight is experiencing a security threat.

This code serves as an important tool in aviation security, enabling ATC to take appropriate action, such as coordinating with law enforcement and providing necessary support to the affected aircraft. It effectively communicates the urgency of the situation and helps ensure that the proper protocols are followed swiftly.

In contrast, codes such as 7600 are used for radio communication failures, 7700 signifies a general emergency that could require assistance for various reasons unrelated to hijacking, and 7800 is not an established transponder code. Understanding these codes and their specific uses is crucial for maintaining situational awareness and ensuring safety in the skies.
