Which action is NOT part of the immediate security response to a threat?

• A. Inform the flight deck and purser, secure yourself and others, reassess the threat, and follow established procedures
• B. Engage in a physical confrontation with the passenger without authorization
• C. Follow the established security procedures
• D. Communicate with the flight deck as needed

Answer: (B)

Immediate security response to a threat centers on coordinated actions, clear communication, and following established procedures rather than acting unilaterally. Engaging in a physical confrontation without authorization is not part of that approach because it bypasses the chain of command, can escalate danger, and may violate safety policies and legal protections. The proper response is to inform the flight deck and purser, secure yourself and others, reassess the threat as new information comes in, and carry out the established procedures. Communication with the flight deck as needed is also essential to keep everyone aligned and to receive authorization or guidance. The correct choice reflects these coordinated, non-escalatory steps; unapproved physical confrontation does not fit this framework.
