Passive security measures are valuable because they help in what way?

• A. They require active attention.
• B. They distract passengers.
• C. They detect suspicious activity without drawing attention.
• D. They replace crew vigilance.

Answer: (C)

Passive security measures work by watching and sensing threats without requiring people to act. They stay in place and operate quietly, letting normal cabin flow continue while still providing protection. The key benefit is that they detect suspicious activity without drawing attention, so issues can be spotted early and discreetly without causing disruption or alerting a potential wrongdoer. They don’t rely on passengers to actively pay attention, and they don’t replace crew vigilance; instead, they complement it by providing continuous, unobtrusive monitoring that informs how the crew responds.
