What is the standard emergency code for hijacking?

The standard emergency code for hijacking is 7500. This code is specifically designated for situations involving aircraft hijacking, allowing air traffic controllers and other aircraft to quickly identify and respond to the situation. The significance of this code lies in its ability to communicate the urgency of the scenario without causing panic or alerting potential hijackers, as pilots can input the code discreetly. Recognizing and using this code is vital for ensuring the safety of passengers and crew members, as well as enabling swift coordination with security authorities. The other codes, while related to different aviation emergencies, serve distinct purposes: 7700 is used for general emergencies, 7600 indicates communication failure, and 7400 is used for unlawful interference that doesn't fit the hijacking category.
