Who is primarily responsible for cabin security checks during a flight?

• A. Ground security before takeoff
• B. The crew, led by the purser or designated security lead, with all crew members participating in a 360-degree preflight and in-flight sweep
• C. The captain alone
• D. The flight deck only

Answer: (B)

Cabin security checks during flight are a coordinated crew effort, led by the purser or designated security lead, with every crew member taking part in a thorough 360-degree sweep both before takeoff and during the flight. This approach ensures every area of the cabin—aisles, seating, lavatories, galleys, and jumpseats—is actively checked for potential threats or hazards, and it allows for rapid identification and reporting of any unusual activity or items. The lead coordinates the checks, assigns roles, and maintains communication with the flight deck so any concerns can be addressed quickly and appropriately. Ground security and the flight deck play important roles, but the ongoing interior checks and security awareness happen on the cabin side as a team effort.
