What is the role of a "chock" in aircraft handling?

• A. To secure an aircraft in place and prevent movement
• B. To assist in the towing of aircraft
• C. To indicate fuel storage areas
• D. To maintain proper distances on the flight deck

Answer: (A)

The primary role of a chock in aircraft handling is to secure an aircraft in place and prevent movement. Chocks are wedge-shaped devices that are placed against the wheels of an aircraft to keep it stationary, especially when it is parked on a ramp or during loading and unloading operations. Their use is critical to ensuring safety, as they prevent unintended movement that could occur due to various factors, such as wind or mismatched weight distributions.

Using chocks effectively helps to maintain control over the aircraft's position, allowing ground crew to work safely around it without the risk of the aircraft rolling or shifting unexpectedly. The importance of this cannot be overstated, as an unsecured aircraft could pose hazards not only to the aircraft itself but also to personnel and equipment in the vicinity.
