Which actions are recommended when securing a heavy aircraft?

• A. Head aircraft into the wind
• B. Install control locks, covers and guards
• C. Chock all wheels for and aft
• D. All of the above

Answer: (D)

When securing a heavy aircraft, you want to minimize wind movement, lock the controls, and physically prevent any rolling. Facing the aircraft into the wind reduces the wind’s ability to push or yaw the airplane around the landing gear, making it harder for gusts to move it unexpectedly. Installing control locks, covers, and guards keeps the flight controls from moving due to wind or handling and protects delicate surfaces from debris or damage. Chocking all wheels on both sides fixes the aircraft in place, preventing any rolling in either direction. When you combine these steps, you’re addressing the main ways a parked aircraft can shift or be damaged, which is why all of these actions are recommended.
