DTA Alizés

The DTA Alizés (Tradewind) is a French ultralight trike that was designed by Michel Guaiguant and is produced by DTA sarl of Montélimar.

The aircraft is a joint venture with wing manufacturer La société Ellipse who market it as the Ellipse Alizé. It is supplied as a complete ready-to-fly-aircraft.

Design and development
The Alizés was designed to comply with the Fédération Aéronautique Internationale microlight category, including the category's maximum gross weight of 450 kg. The aircraft also fits the US FAR 103 Ultralight Vehicles rules.

The Alizés features a cable-braced Ellipse Fuji hang glider-style high-wing, weight-shift controls, a single-seat open cockpit with no cockpit fairing, tricycle landing gear without wheel pants and a single engine in pusher configuration.

The Alizés is a very simple nanotrike and is made from bolted-together aluminum tubing, with its single surface wing covered in Dacron sailcloth. Its 10 m span wing is supported by a single tube-type kingpost and uses an "A" frame weight-shift control bar. The powerplant is a single cylinder, air-cooled, two-stroke, 22 hp Zenoah G25 engine. The aircraft has an empty weight of 72 kg and a gross weight of 170 kg, giving a useful load of 98 kg. With full fuel of 10 L the payload is 91 kg.

Due to its single seat configuration and "niche appeal", the aircraft has not sold in large numbers.
