Is the key lock monitored on the aircraft?

• A. Yes
• B. No
• C. Not Monitored
• D. Sometimes

Answer: (C)

The key lock is not monitored on the aircraft because it is a mechanical, non-sensing component. The onboard fault-detection and monitoring systems only track items that provide electrical signals or data to the aircraft’s avionics. A lock itself doesn’t feed a sensor or alert when it’s engaged, so there isn’t a cockpit or systems indication for “lock status.” Instead, crew verify secure latches and doors through physical checks as part of preflight and normal procedures. If a lock were monitored, you’d expect an alert or a status display; since that isn’t the case, the correct understanding is that the key lock is not monitored.
