The BRM Aero Bristell is a Czech low-wing, two-seat in side-by-side configuration, single engine in tractor configuration, ultralight and light-sport aircraft that was designed by Milan Bristela and is produced by BRM Aero. The aircraft is supplied as a complete ready-to-fly aircraft.[1][2]

The aircraft was introduced at the AERO Friedrichshafen 2011 show.[3]

Design and development[edit]

The aircraft was designed to comply with both European microlight rules and also the US light-sport aircraft regulations, by using different versions for each regulatory environment.[1][2]

The aircraft is made from aluminium and features a 130 cm (51 in) wide cabin at the shoulder, with a bubble canopy over the cockpit. The wings feature flaps. The standard engine is a 60 kW (80 hp) Rotax 912UL, with the 75 kW (101 hp) Rotax 912ULS, the 71 kW (95 hp) ULPower UL260i/iS and the 88 kW (118 hp) ULPower UL350iS powerplants optional. The 115 hp (86 kW) Rotax 914, 85 hp (63 kW) Jabiru 2200 and 120 hp (89 kW) Jabiru 3300 are also available. Other engines are planned, particularly for the United States market. The aircraft has a notably high useful load of 279 kg (615 lb). The landing gear is of tricycle configuration.[1][3]

After 42 examples had been completed the aircraft was introduced into the US market in September 2011 at the AOPA Summit.[1]
