Which threat level is defined by an attack on the flight deck?

• A. Level Two
• B. Level One
• C. Level Three
• D. Level Four

Answer: (D)

An attack on the flight deck represents the most severe, immediate danger to the aircraft and everyone on board. Because it directly compromises cockpit control and the pilots’ ability to operate the plane, it requires the highest level of security response. Level Four signals that the threat is active or imminent and demands maximum, urgent measures to protect lives, secure the cockpit, notify authorities, and coordinate with ground security and air traffic control. Other threat levels describe less direct or less certain risks, but an actual attack on the flight deck is treated as the most critical scenario.
