Aviasud Mistral

The Aviasud Mistral is a French two-seat ultralight biplane built by Aviasud Engineering. This plane is notable as it has forward swept wings and side-by-side seating. The lower wings are movable and are used as the roll control (wing leveler).

Design and development
The Aviasud Mistral has a biplane configuration

The Aviasud Mistral was designed by two Belgian engineers, Francois Goethals and Bernard d'Otreppe.

The prototype first flew in May 1985,[2] and the aircraft entered production with AviaSud engineering in Fréjus,[3] with the first production model having its maiden flight in February 1986.[2] Aviasud has built more than 200 Mistrals, it has also been built by Ultraleger Industria Aeronáutica Ltda in Brasil.[1]

The Mistral is a biplane of mixed wooden and composite construction, with forward swept wings, with the all-moving lower wings used as large ailerons, and a conventional, all-moving tailplane. It has a fixed tricycle landing gear and a nose-mounted Rotax piston engine. The Mistral has an enclosed cockpit with two side-by-side seats forward of the wings.[1][2]

On May 4, 1987, an Aviasud Mistral was flown to the geographic North Pole by Nicolas Hulot, a world first for this type of aircraft.
