What is the primary function of the main gear chocks?

• A. To control the hydraulic systems
• B. To secure the aircraft in place
• C. To enhance fuel efficiency
• D. To adjust the aircraft's balance

Answer: (B)

The primary function of the main gear chocks is to secure the aircraft in place. Chocks are essential safety devices used to prevent the aircraft from rolling or moving unexpectedly while on the ground, especially when parked. By placing the chocks in front of or behind the main wheels, ground crew members ensure that the aircraft remains stable and stationary during maintenance, loading, or unloading procedures. This is critical for the safety of personnel and equipment around the aircraft. When considering the context of the other options, controlling hydraulic systems refers to the operation of the aircraft's hydraulic mechanisms, which is unrelated to the purpose of chocks. Enhancing fuel efficiency pertains to aerodynamics and engine performance, not the physical security of the aircraft. Adjusting the aircraft's balance involves weight distribution management, which is also not the function of the chocks. Therefore, the correct understanding of the main gear chocks emphasizes their role in grounding and securing the aircraft, contributing to overall operational safety.
