What is the function of a chock in aircraft handling?

• A. To lift the aircraft during maintenance
• B. To prevent aircraft from rolling or moving unintentionally
• C. To mark the parking spot for the aircraft
• D. To distribute weight evenly during loading

Answer: (B)

The primary function of a chock in aircraft handling is to prevent the aircraft from rolling or moving unintentionally. Chocks are typically wedge-shaped blocks made of wood or rubber, placed against the wheels of the aircraft when it is parked. Their design ensures that they fit snugly against the tires, effectively blocking any potential movement caused by wind, uneven ground, or any other forces. This is crucial for ensuring the safety of the aircraft, ground crew, and equipment in the vicinity.

The other functions mentioned, such as lifting the aircraft, marking the parking spot, or distributing weight during loading, do not accurately describe the role of chocks. Lifting an aircraft requires jacks or other lift mechanisms, while marking parking spots is typically done using painted lines or markers. Additionally, weight distribution during loading involves planning and equipment focused on balance rather than chocks, which are solely designed for stabilization.
