About the Direct Fly Alto

The Alto 912 TG is a Czech-built light sport aircraft designed and manufactured by Alto Aviation in the early 2000s. Certified under both European CS-LSA and U.S. FAA LSA regulations, the Alto occupies the ultralight / light sport niche with a maximum takeoff weight of exactly 1,320 pounds, the upper limit for the LSA category in the United States.

Powered by a single Rotax 912 series engine (typically the 100-hp 912 ULS), the Alto features a high-wing configuration, tricycle landing gear, and side-by-side seating for two. Its docile handling characteristics and relatively low operating costs have made it popular among flight schools and private owners in Central Europe and North America. The type's stall speed of 37 knots in landing configuration and never-exceed speed of 120 knots place it squarely in the trainer and recreational touring mission profile.

While not breaking any records, the Alto represents a straightforward, affordable entry point into certificated light sport flying, competing with designs like the Czech Sport Aircraft SportCruiser and Flight Design CT series. SkyMeter has tracked flights across airframes and operators, with the largest observed operator.
