Wheel chocks immobilize the aircraft when it’s on the ground. They should be used whenever the airplane is parked and during fueling or servicing, because wind, slope, or external forces from ground equipment can push it even if the parking brake is set. Chocks provide a simple, reliable safeguard to keep the aircraft in place until it’s ready to move. They are removed before taxiing or starting to move the aircraft.
