Who conducts the 360-degree preflight and in-flight security sweep?

• A. The flight deck only
• 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. Ground staff on the tarmac
• D. The catering team

Answer: (B)

The idea is that security checks aboard a flight are a team effort coordinated by a leader on board. A 360-degree preflight and in-flight sweep involves the entire crew working together to inspect every area of the cabin—galleys, lavatories, seating areas, aisles, jump seats, and service spaces—so nothing is overlooked. The purser or a designated security lead directs the effort, assigns roles, and communicates findings to ensure comprehensive coverage and a quick response if anything suspicious is found. This approach ensures every corner is checked and maintains a clear chain of responsibility. It isn’t handled by the flight deck alone, since pilots’ primary focus is operating the aircraft; ground staff on the tarmac aren’t present in the cabin during flight, and the catering team isn’t tasked with ongoing security sweeps.
