ABSTRACT:
An aircraft provided with airfoils of the non-rotating type that are configured and arranged to provide greater lift while at the same time offering stable flight at ultra-low airspeeds. The airfoils are arranged as a biplane and consist of a fixed wing and a movable wing which are designed so as to permit a much steeper takeoff and landing angle as well as offering more efficient flight at higher speeds with greater inherent safety.
