When is the final preflight walk-through supposed to be completed?

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

Answer: (D)

Timing the final preflight walk-through to occur during boarding keeps the departure process smooth. It provides a last check of the aircraft’s readiness while passengers are still boarding, so any issues—like a door not fully closed, a loose panel, or a visible safety concern—can be spotted and addressed before pushback. This way, once boarding ends, the crew can proceed to push back with minimal delay, knowing the exterior and cabin are in proper condition.
