What does unlawful interference mean in aviation security terms?

• A. Any action by a passenger that disrupts cabin service.
• B. Unauthorised crew decisions.
• C. Any action by a passenger that threatens the safety of the aircraft or its occupants, such as hijacking or attempting to seize control.
• D. Security incidents are only those involving weapons.

Answer: (C)

Unlawful interference in aviation security means any action by a passenger that threatens the safety of the aircraft or its occupants, such as hijacking or attempting to seize control. This focuses on actions that put flight safety at risk, not merely inconveniencing crew or making internal decisions.

The other ideas don’t fit because disrupting cabin service isn’t inherently a security threat to the aircraft, and unauthorized crew decisions concern internal operations rather than passenger actions that endanger safety. And security incidents aren’t limited to weapons; unlawful interference includes a range of dangerous acts that threaten the flight, including attempts to seize control.
