In the post-landing sequence, which action follows securing controls?

• A. Unlock.
• B. Taxi to parking.
• C. Shut down engines.
• D. Set parking brake.

Answer: (A)

The key idea is that after landing you secure the flight controls to prevent any unintended movement while the aircraft is on the ground. Before you can actually move the airplane—taxiing to parking—you need to regain control authority, so you unlock the controls. Once unlocked, you can taxi to the parking area, then set the parking brake and shut down the engines as part of the post-landing shutdown sequence. The unlock step is what enables ground maneuvering after the controls have been secured.
