When aligning flight crew readiness, when must the final preflight walk-through be done?

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

Answer: (C)

The final preflight walk-through is a last-check performed once boarding has begun to confirm cabin readiness and exterior condition before engines are started. Doing it after passengers have boarded lets you verify that doors are closed and locked, cabin equipment is secured, serviceability items are addressed, and any issues can be resolved while there is still time before pushback. If you waited until after engine start, you’d miss the chance to correct problems safely and efficiently. Conversely, doing it before boarding wouldn’t reflect the actual state of the aircraft with passengers on board and ready to fly.
