Chocks are used for what purpose?

• A. Protect engines from dust
• B. Stabilize the aircraft by placing wood or rubber blocks at the wheels
• C. Mark the parking position
• D. Signal the start of boarding

Answer: (B)

Chocks are used to prevent the aircraft from moving when it’s parked. They are wedge-shaped blocks placed against the wheels—often on both sides of a wheel or both wheels on a standstill—to block any rolling caused by wind, a slope, or a temporary brake release. Wood or rubber blocks are common materials, chosen for their durability and ability to withstand the weight of the aircraft. They stay in place during boarding and ground handling and are removed before taxiing for takeoff. This safety measure keeps the aircraft from drifting unintentionally, while the other options describe unrelated tasks like dust protection, parking markings, or signaling boarding.
