Leading additional aircraft aileron wings for increased lift are mounted on a pivot axis to be swung clear to avoid fouling ground service units when it is parked on the ground

摘要

The leading ailerons at an aircraft fuselage, for additional lift especially during climbing and descending maneuvers, are structured so that the aileron wing (1) can swing on an axis on at least one side of the fuselage near the front fuselage door, when parked on the ground. The swing axis is generally parallel to the fuselage longitudinal axis of the aircraft (2). It can swing at an angle of 90 deg /30 deg into a flapped position.
