When do you do periodic flight deck checks?

• A. No more than every 60 minutes on flights
• B. No more than every 90 minutes on flights over 2 hours
• C. Every 120 minutes
• D. Only before take-off and after landing

Answer: (B)

Periodic flight deck checks are a safety practice on longer flights to maintain continual cockpit oversight and security. On flights over two hours, these checks should be done no more than every 90 minutes. This interval balances keeping the flight deck under watch with giving crew time for necessary rest and routine cockpit duties, so potential issues—equipment alerts, door status, or crew readiness—can be detected promptly without excessive disruption. Doing them more frequently (like every 60 minutes) would bog down operations and reduce rest opportunities, while waiting longer (like 120 minutes) could leave the cockpit unattended too long and miss emerging problems. Checking only before take-off and after landing ignores mid-flight contingencies and security needs.
