The AeroJames 01 Isatis is a French two-seat microlight landplane developed by AeroJames, based in Ajaccio, Corsica. Introduced to the public at the Aero Friedrichshafen show in 2009, the aircraft was marketed as a ready-to-fly option for the sport pilot and private owner market. The production window for the Isatis 01 spanned approximately from 2009 until early 2018, at which point the manufacturer effectively ceased operations, as evidenced by the company's website being listed for sale.
Designed to comply with the Fédération Aéronautique Internationale (FAI) microlight rules, the Isatis 01 features an all-composite airframe. Its configuration consists of a strut-braced high wing and a fixed tricycle landing gear. The cockpit is enclosed and accommodates two occupants in a side-by-side seating arrangement. To remain within the European microlight mass limit, the aircraft was designed with a maximum takeoff weight of 472.5 kg, a figure that includes allowances for a ballistic parachute.
Technically, the Isatis 01 is notable for its powerplant. Unlike many aircraft in its class that utilize Rotax engines, the Isatis 01 employs a BMW four-stroke, two-cylinder, air-cooled, horizontally-opposed piston engine derived from BMW motorcycles. This 100 hp (75 kW) engine is mounted behind the cockpit and drives a three-bladed composite propeller in a tractor configuration. This engine choice contributes to the aircraft's relatively high performance for a 100-hp microlight, with a reported cruise speed of 230 km/h (140 mph) and a maximum speed of 270 km/h (170 mph).
Other verified technical specifications include a wingspan of 9.80 meters, a length of 6.0 meters, and a height of 2.6 meters. The wing area is 12.0 square meters, and the aircraft has an empty weight of 270 kg. It carries 64 liters of fuel, which provides a documented maximum range of 800 nautical miles according to ICAO data. The stall speed is recorded at 60 km/h. While the aircraft served a civil role in general aviation as a recreational touring and training aircraft, there is no record of military service or scheduled commercial use. Due to its limited production and the subsequent disappearance of AeroJames, the total number of units built and the number of surviving airframes remain undocumented.
