Which threat level corresponds to a life-threatening weapon?

• A. Disruptive
• B. Weapon-life threatening
• C. Physical abuse
• D. Attempted to breach the flight deck

Answer: (B)

Threat levels guide how urgently a crew must respond to danger, with the most urgent level reserved for weapons capable of causing death or serious injury. When a weapon is life-threatening, the threat is immediate and the necessary actions are rapid and decisive: alert the flight deck and authorities on the ground, secure passengers, use restraint if it can be done safely, and consider diversion or emergency landing as required. Other scenarios describe harmful behavior or breach attempts that are serious but do not inherently involve a weapon that could cause fatal harm, so they align with different, less urgent levels.
