What is a Chock? Definition, Types, and Uses in Aviation and Transportation

Chock is a term that is commonly used in the context of aviation and transportation. It refers to a device or piece of equipment that is used to prevent a vehicle or aircraft from moving or rolling.

In aviation, chocks are typically made of rubber or plastic and are placed under the wheels of an aircraft to keep it from rolling or moving while it is parked or being serviced. They are often used on the ground to prevent the aircraft from moving during maintenance or refueling operations.

In transportation, chocks may be used to prevent vehicles from rolling or moving while they are being loaded or unloaded. For example, chocks may be placed under the wheels of a truck or train car to keep it from rolling while cargo is being loaded or unloaded.

Overall, the purpose of a chock is to provide a stable and secure foundation for a vehicle or aircraft, allowing it to remain stationary and preventing it from moving or rolling.
