The present invention is structured such that, as for travelling on the ground, there is provided a braking mechanism capable of braking wheels by the use of a single brake pedal or a braking mechanism capable of braking the wheels by flare out operation of a control stick, while automatic control of traveling direction is performed in flight using a yaw damper. In addition, a larger braking force is automatically generated, without manual operations by a pilot, for landing gear mounted on the side of an airframe toward which direction of an aircraft is to be changed as compared with the braking force applied to landing gear on the other side.
