What is the emergency transponder code for hijack?

• A. 7500
• B. 7700
• C. 7600
• D. 7777

Answer: (A)

In aviation, a four-digit transponder code is used to signal different kinds of emergencies to air traffic control. The code for hijack is 7500. Setting this code tells ATC that the aircraft is subject to unlawful interference and requires immediate security-focused handling. It helps ATC prioritize the situation, coordinate with authorities on the ground, and guide other aircraft to maintain separation and support a safe resolution. The other codes indicate different issues: 7700 signals a general emergency affecting the aircraft’s safety, 7600 means radio communications failure, and 7777 is not an official emergency code. So the hijack signal is distinct and specifically communicates unlawful interference to prompt the appropriate response.
