Aero At At-3 R100

Single Piston

The Aero AT-3 R100 is a Czech-designed two-seat high-wing light sport aircraft that emerged from the lineage of the Aero Ae-270 Ibis, a 1990s ultralight trainer. Built by Aero Vodochody's general aviation division (later spun off as Aero AT), the AT-3 features a distinctive T-tail, fixed tricycle gear, and a spacious side-by-side cabin with excellent visibility through its bubble canopy. Powered by a Rotax 912 ULS engine producing 100 horsepower, it represents the company's effort to capture the American Light Sport Aircraft market following the 2004 LSA rule changes. The aircraft's composite construction keeps empty weight around 650 pounds, allowing it to meet LSA limits while offering a useful load approaching 800 pounds—generous for the category. Its docile handling characteristics and forgiving stall behavior made it popular as a trainer in Europe, though it never achieved significant market penetration in North America against established competitors like the Flight Design CT and Tecnam P92. The type's operating envelope is typical for the LSA class: never-exceed speed of 135 knots, normal operations below 108 knots, and stall speeds in the high 30s with full flaps. Maximum cruise is around 100 knots at 75% power, with endurance of roughly four hours on 16 gallons of fuel. SkyMeter has tracked 23 flights across 14 airframes and 8 operators over routes, with DELANEY TIMOTHY P the largest observed operator.
