Шаблон:Infobox Aircraft Type
The Aeroprakt A-20 Vista is a family of Ukrainian tandem two-seat high-wing, strut-braced, pusher configuration conventional landing gear, ultralight aircraft, produced by Aeroprakt. The A-20 was introduced into the North American market at AirVenture 1999.[1][2]
Design and development
Design of the A-20 began in 1990, with the first prototype making its maiden flight on 5 August 1991, with the first production aircraft flying on 15 August 1993.[3] The A-20 is constructed with a fiberglass forward fuselage and cockpit with aluminium wings and tail surfaces covered in doped aircraft fabric. The wing is fitted with half-span ailerons and flaps. The flaps are quite effective and lower the landing speed to Шаблон:Convert. Flaperons are available on some models. The conventional landing gear has steel sprung main gear legs.[1][2]
The A-20 was originally designed for the Шаблон:Convert Rotax 503 two-stroke aircraft engine. The low drag airframe produces acceptable performance on this low power output. Optional engines include the Шаблон:Convert Rotax 582 and Шаблон:Convert Rotax 912ULS[1][4]
Operational history
An A-20 won the European Microlight Championship in 2002.[2]
