How often must the flight deck be physically checked for safety during flights longer than 2 hours?

The correct response indicates that flight attendants must physically check the flight deck for safety every 90 minutes during flights that exceed 2 hours in length. This practice is essential for ensuring that all safety protocols are being adhered to and that the flight deck remains secure throughout the journey.

Regular checks help to monitor the situation inside the flight deck and ensure that all equipment remains operational and secure. This interval strikes a balance between maintaining safety and operational efficiency, allowing flight attendants to monitor the cabin and attend to passenger needs while still ensuring compliance with safety standards. Maintaining this schedule of checks contributes to overall safety during longer flights by allowing for timely response to any irregularities or safety concerns that may arise in the cockpit environment.

While the other intervals might initially seem reasonable, they do not align with established safety protocols that emphasize the importance of frequent and regular checks to enhance safety on extended flights.
