Prior to passenger boarding, at what time should the final preflight walk-through be completed?

• A. Before boarding begins
• B. After boarding begins
• C. During boarding
• D. After engine start

Answer: (A)

The final preflight walk-through is done before passengers begin boarding to confirm the aircraft is safe and ready for flight. This check verifies there are no hazards around the aircraft, that exterior conditions are good, and that key surfaces and systems are accessible and functioning. Completing it before boarding allows any needed fixes to be made without delaying boarding and before engines are running, reducing risk to crew and passengers. Waiting until after boarding or after engine start would create safety risks and potential delays, so the best time is before boarding begins.
