After a security incident requiring lockdown, what are the cabin-crew steps?

• A. Stand by and wait for orders from a supervisor.
• B. Notify the Captain, secure all exits, account for passengers, maintain silence, and await further instructions from authorities.
• C. Initiate evacuation immediately.
• D. Contact passengers to explain the situation.

Answer: (C)

During a security incident that requires a lockdown, the priority is to keep people safe and control the environment until authorities give directions. The best sequence is to promptly notify the Captain about the incident, secure all exits and entry points to prevent access, take a careful headcount to account for everyone on board, maintain a quiet and controlled cabin to avoid drawing attention or causing panic, and await further instructions from authorities or the flight deck.

Evacuation right away isn’t appropriate in a lockdown because it can expose passengers to danger and would typically require clearance from the Captain or authorities after assessing the threat. Communicating details of the incident to passengers should be limited and only as directed by the Captain, since unnecessary explanations can spread alarm and complicate the response.
