When the combination of the aircraft and the land vehicles is finished, the aircraft is required to be limited and restrained to maintain the stability of the relative position between the aircraft and the land vehicles in order to avoid damage caused by excessive shaking of the aircraft relative to the land vehicles under the special working conditions of collision, emergency braking, curve driving, speed-reducing zone passing and the like.
