What level involves an attack on the flight deck requiring LEO reaction?

• A. Level 2 - Physical, potentially no reaction from LEO
• B. Level 1 - Verbal, no reaction from LEO
• C. Level 4 - Attack on the flight deck, LEO reacts
• D. Level 3 - Potential Serious Bodily Injury or Life Threatening, LEO reacts

Answer: (C)

Understanding incident levels centers on matching threat severity with the required LEO response. An actual attack on a critical area like the flight deck represents a high-severity, in-progress threat that demands immediate intervention by law enforcement. This is why the level describing an attack on the flight deck with LEO reacting is the highest-priority category. It signals that the threat is active and severe, with potential for serious harm, and warrants rapid, decisive action to stop the attack.

In contrast, verbal incidents or physical threats that don’t prompt an immediate LEO response are categorized at lower levels, and a Level 3 scenario involves potential serious injury or life-threatening harm but not necessarily an ongoing assault on a protected area requiring instantaneous action. Therefore, the scenario where an attack on the flight deck triggers an immediate LEO reaction best fits Level 4.
