It was a monoplane-parasol with a wing of a large elongation (12.5), which allowed to increase the aerodynamic quality of the airframe and improve its planning properties.  A distinctive feature of AVF-5 was the device of transverse control: ailerons were absent, and instead of them "goshirovanie" - curvature of the surface of the wing itself was used.  This lateral control, which was previously installed on the first Newport and Moran aircraft, was used, in all probability, to reduce weight and simplify the design of the wing.  We built a glider in the glider circle of the Workshops of heavy artillery in Lefortovo. The AWF-14 training glider was created in the workshop of the Air Fleet Academy.  It was a free-carrying monoplane with a wing of great elongation (13.6), reinforced from above with a relatively low fuselage.  The wing in the plan had an arcuate front and a straight trailing edge, a large fraction of the trailing edge of the wing was occupied by ailerons.  The pilot was placed in the cockpit of the fuselage in front of the leading edge of the wing.
