When should a diversion or evacuation be considered according to the procedural guidance?

• A. Immediately upon suspicion
• B. If directed by authorities or flight deck as part of the plan.
• C. Never
• D. Only after landing

Answer: (B)

Coordinated action under established authority guides diversion or evacuation. In security procedures, a diversion or evacuation isn’t started on suspicion alone; it’s carried out when directed by the flight deck or by authorities as part of the approved plan. This ensures the response is synchronized with air traffic control, emergency services, and the overall safety strategy, reducing confusion and risk for passengers and crew.

Acting purely on suspicion can disrupt the flight without the necessary coordination, and waiting until after landing would miss a critical safety window. Following the plan and the directing authority keeps everyone on the same page and allows a timely, effective response.
