Additional wing is mounted on struts of required height. Maneuvering flap may deflect through definite angle when it is necessary to increase lifting force and to form deceleration effect.

EFFECT: extended maneuvering capabilities of aircraft; rational use of upper surface of fuselage and excluding use of landing flap on lifting wing.
