Mistral General information Type Ultralight biplane National origin France Manufacturer Aviasud Engineering Number built 250+ (1999) History Introduction date 1986 First flight 1985

The **Aviasud Mistral** is a French two-seat [ultralight](/source/Ultralight_aviation) [biplane](/source/Biplane) built by [Aviasud Engineering](/source/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).

The aeroplane (along with the [Sirocco](/source/Aviasud_Sirocco)) was taken over, and is still supported by, [Aériane](/source/A%C3%A9riane) in 1989.[1]

## 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](/source/Fr%C3%A9jus),[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 unidentified 3-axis ULM which was the basis for the Mistral[4]

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](/source/Aileron), and a conventional, all-moving [tailplane](/source/Tailplane). It has a fixed [tricycle landing gear](/source/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](/source/Nicolas_Hulot), a world first for this type of aircraft.
