The TL Ultralight TL-22 Duo is a Czech ultralight trike that was designed and produced by TL Ultralight of Hradec Králové. Production has been completed, but when it was available the aircraft was supplied as a complete ready-to-fly-aircraft or as a kit for amateur construction.[1]

The aircraft was designed to comply with the Fédération Aéronautique Internationale microlight category, including the category's maximum gross weight of 450 kg (992 lb). The aircraft has a maximum gross weight of 361 kg (796 lb). It features a cable-braced hang glider-style high-wing, weight-shift controls, a two-seats-in-tandem open cockpit with a cockpit fairing, tricycle landing gear with wheel pants and a single engine in pusher configuration.[1]
The aircraft is made from bolted-together aluminum tubing, with a fibreglass cockpit fairing and its double surface wing covered in Dacron sailcloth. Its 10.6 m (34.8 ft) span wing is supported by a single tube-type kingpost, uses an "A" frame weight-shift control bar and has a wing area of 13.8 m2 (149 sq ft). The standard powerplant used is a twin cylinder, liquid-cooled, two-stroke, dual-ignition 64 hp (48 kW) Rotax 582 engine. The aircraft has an empty weight of 160 kg (353 lb) and a gross weight of 361 kg (796 lb), giving a useful load of 201 kg (443 lb).
