What is the definition of flight deck lockdown?

• A. The Suspension of Traffic Between the Passenger Cabin and the Flight Deck Door
• B. Blocking Communications to the Flight Deck
• C. Locking the Flight Deck Door Without Other Restrictions
• D. Closing All Cabin Doors

Answer: (A)

Flight deck lockdown means suspending traffic between the passenger cabin and the flight deck door. In practice, the cockpit remains secured with the door closed and no one from the cabin is allowed to approach or enter, so the crew can manage a security situation with the flight deck isolated. It’s about restricting movement through that doorway, not just locking the door or closing other cabin doors. The other options describe actions that don’t capture the intent of isolating the flight deck from cabin traffic.
