Which of the following is NOT listed as a primary in-flight security measure?

• A. Hardened flight deck doors
• B. CCTV monitoring of the cabin
• C. Federal Flight Deck Officer Program
• D. Passenger intervention

Answer: (C)

In-flight security measures focus on deterrence, detection, and rapid response during the flight. Hardened flight deck doors provide a strong physical barrier to prevent unauthorized cockpit access. CCTV monitoring of the cabin helps the crew observe activity, spot suspicious behavior, and act quickly. Passenger intervention leverages trained crew and alert travelers to report concerns and assist in stopping a threat early. The Federal Flight Deck Officer Program, while an important security policy that expands on-board capabilities by authorizing some pilots to carry firearms, is not a baseline, universally deployed primary in-flight security measure. It represents a policy option rather than a standard security control used on all flights.
