For safety checks, when should the final preflight walk-through be finalized?

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

Answer: (A)

The main idea is that the final preflight walk-through should be completed before boarding begins. Completing this safety check while the aircraft is unoccupied lets the crew verify exterior condition, control surfaces, tires, fuel caps, lights, and other critical items without passengers in the way. Any faults found can be addressed right away, ensuring the aircraft is safe and ready before people climb aboard. If the walk-through waits until after boarding has started, or while boarding is in progress, it risks delaying passengers, creating safety hazards, and complicating corrective actions with people on board or engines potentially already running. So the best time is before boarding begins.
