The main purpose of wheel chocks is to prevent aircraft movement while parked. When an aircraft is stationary, especially on a ramp or tarmac, the risk of it rolling due to mechanical issues, wind, or other external factors exists. Wheel chocks are simple, wedge-shaped blocks positioned against the wheels of the aircraft to provide stability and securely hold it in place. This is crucial for safety as it helps protect ground personnel, equipment, and the aircraft itself from accidents that could occur if the aircraft were to accidentally roll. Proper use of wheel chocks is a fundamental safety practice in aviation that ensures that the aircraft remains securely stationed until it is ready for further operation.
