During an attempted hijacking, which action is listed as the initial response in the protocol?

• A. Lockdown procedure implemented
• B. Captain reports to ATC and declares emergency PAN/MAYDAY
• C. If threat of explosive device, follow non-normal checklist BOMB ON BOARD and activate SAAP
• D. Maintain contact with flight crew

Answer: (A)

The first thing to do in a hijacking threat is to quickly secure the environment by implementing lockdown procedures. Locking down focuses on restricting access to the cockpit and cabin, controlling passenger movement, and stabilizing the situation so crew can operate safely without the immediate risk of intrusion or disruption. This action buys time, preserves safety, and creates a controlled setting for the crew to assess the threat, coordinate with ground support, and determine the next steps.

Communicating with air traffic control and declaring an emergency is indeed essential, and will occur as part of the broader response, but it follows the initial security measure that immediately reduces opportunity for escalation. The bomb-threat checklist and activation of specialized plans would be invoked only if a specific threat is identified, and maintaining contact with the flight crew is ongoing throughout the incident, not the initial protective action.
