A human-machine interface (HMI) system enables people to more easily control the air vehicle for UAM with a familiar method. The control system includes a steeling wheel operated for steering of the air vehicle, an accelerator pedal operated for acceleration of the air vehicle, and a decelerator pedal operated for deceleration and braking of the air vehicle. An altitude designating device selects and designates a target altitude and a controller generates a control command for adjusting altitude, acceleration, deceleration and braking, and steering of the air vehicle, based on air vehicle driving information. A drive device is then operated according to the control command generated from the controller.
