The present invention relates to a new helicopter air plane where a helicopter and a generic air plane can be used. A propeller group is installed inside a pipe to use a method for floating and landing and advancing an air vehicle, and a rudder for rotating the air vehicle toward a left side and a right side and another rudder for enabling the air vehicle to be ascended and descended are installed in the present invention. Therefore, the present invention is capable of freely flying after the air vehicle takes off and safely landing when a defect of the air vehicle is generated since an emergency propeller is installed in an upper portion of the air vehicle and installing the propeller which rotates 360°C toward the right side and the left side in the rear side of the air vehicle to freely switch directions in any spaces.
