At what stage should the final preflight walk-through be concluded?

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

Answer: (B)

The final preflight walk-through is a safety check done at a stage when the aircraft can still be safely inspected without passengers on board. Completing it before boarding begins ensures that any issues—like a loose door, a chock, a snag on the exterior, or equipment left attached—are found and resolved without the distraction or delay of passengers moving through the cabin. It also prevents the need to delay boarding or start procedures if something is amiss, since you’ve already confirmed the exterior and flight-critical items are in good order. In short, this check should be finished prior to passengers boarding so the aircraft is confirmed safe and ready to start operations.
