Light Wing AC4
The Light Wing AC4 is a Swiss ultralight and light-sport aircraft, designed by Hans Gygax and produced by Light Wing AG Aviation of Stans. The aircraft is supplied as a complete ready-to-fly-aircraft.[1]
Design and development
The AC4 was designed to comply with the Fédération Aéronautique Internationale microlight rules and US light-sport aircraft rules. It features a strut-braced high-wing, a two-seats-in-side-by-side configuration enclosed cockpit, fixed tricycle landing gear and a single engine in tractor configuration.[1]
The aircraft is made from a combination of composites and aluminum sheet, with its tailboom made from a single large diameter aluminium tube and the wings and tail surfaces covered in aluminium. Its 9.60 m (31.5 ft) span wing has an area of 16.65 m2 (179.2 sq ft), is supported by V-struts and mounts flaps. The standard engine available is the 100 hp (75 kW) Rotax 912ULS four-stroke powerplant.[1]
The AC4 can optionally be fitted with two extra seats in the luggage compartment and was also designed for aero-towing gliders. It can also accommodate a stretcher for Medevac missions.[1]
