Which option describes the proper timing for the final preflight walk-through?

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

Answer: (D)

The timing being tested is when the final preflight walk-around should occur in relation to passenger boarding. This walk-around is the last exterior check done before departure, and it should happen after boarding begins. Doing it once boarding has started allows the crew to confirm that doors are properly closed and secured, exterior surfaces and areas around the aircraft are clear, and any last-minute issues observed during boarding can be addressed before engines are started or the aircraft pushes back. If it were done before boarding, you wouldn’t yet have the cabin/boarding context to ensure everything is set for departure; during boarding would risk delaying passengers, and after boarding begins ensures the check is timely and efficient before pushback.
