    Abstract: The present invention discloses an aircraft capable of vertical take-off and landing. The aircraft comprises a single constant speed variable pitch propeller (3), a fuselage (2), an empennage (21, 22) and main wings (6) fixed to the fuselage (2); arranged similar to a conventional aircraft, but sized and positioned for vertical flight. A stator is positioned a minimal distance behind the propeller so as to compensate the torque caused by the propeller. The aircraft comprises high lift and high drag devices such as flaps (19) and a leading edge slat (7) on the main wings (6), and a fuselage spoiler (18). The positioning of the center of gravity (23) allows for a stable nose-up take-off and landing, NUTOL, position. The propeller generated airflow (PGA) over the main wings (6) and high lift and drag devices (7, 18, 19) creates lift and drag forces.
