What action ensures the aircraft is safely shutdown in a parking spot with chocks installed?

• A. Engine shutdown
• B. Fueling
• C. Engine start
• D. Airstart checklist

Answer: (A)

Shutting down the engine is the action that stops all engine motion and removes power from the aircraft systems. Even with chocks in place, leaving the engine running can allow residual energy, hydraulic or electrical systems, or wind forces to cause unintended movement or hazards. By turning the engine off and following the standard shutdown steps, you ensure the aircraft is truly secured and cannot re-ignite or shift. After the engine is off, confirm other safety steps per procedure (parking brake/set, systems off) to maintain a safe parked state.
