FAA Ground School Practice Test

Which of the following codes is associated with a hijacking scenario that pilots should avoid?

1. 7500

2. 7600

3. 7700

4. 1200

The correct answer is: 7500

The code that is associated with a hijacking scenario is 7500. This transponder code is specifically designated to alert air traffic control that an aircraft is being unlawfully interfered with. When pilots set their transponder to 7500, it indicates a hijacking situation, prompting air traffic control to take immediate action to ensure the safety of the flight and its passengers. In contrast, the other codes serve different purposes: 7600 is used to indicate a radio communications failure, alerting controllers that a pilot cannot communicate, while 7700 signals an emergency that requires urgent attention, although it is not specifically related to hijacking. The code 1200 refers to VFR (Visual Flight Rules) operations in uncontrolled airspace and does not signify any emergency or unlawful interference. Understanding these codes is essential for maintaining safety and effective communication in aviation operations.
