When do you lock down the aircraft?

• A. At Any Threat Level
• B. Only During High Threat
• C. After Landing
• D. Before Takeoff

Answer: (A)

Lockdown should be started whenever there is any threat indicator, not waiting for the highest threat. The idea is to secure the aircraft immediately to restrict access to the cabin and flight deck, protect crew and passengers, and give security teams time to assess and respond. Initiating lockdown at the first sign of concern keeps the aircraft in a controlled state and reduces opportunities for tampering or escalation. Waiting for a high threat can allow a situation to worsen, and delaying lockdown until before takeoff or after landing leaves the aircraft vulnerable during other critical moments. So, lock down at any threat level to maintain security and safety while the situation is evaluated and until authorities lift the restriction.
