About the Schempp-Hirth Arcus

The Schempp-Hirth Arcus is a German-built two-seat high-performance sailplane that represents the pinnacle of modern glider design with self-launch capability. Introduced in 2006, the Arcus combines a 20-meter wingspan with an optional retractable sustainer engine, allowing pilots to take off independently and climb to soaring altitude without a towplane, a significant operational advantage for cross-country and competition flying. The type holds multiple world records in the two-seat class and has become a favorite among glider clubs and private owners seeking both training capability and serious cross-country performance.

Its 18-meter flapped wing variant offers exceptional glide ratios exceeding 50:1, while the sustainer engine provides strategic flexibility for outlanding avoidance and return-to-base in marginal conditions. The Arcus features modern composite construction, side-by-side seating for improved instruction and shared flight experience, and sophisticated instrumentation that has made it competitive in FAI racing events. With a never-exceed speed of 168 knots and a stall speed around 46 knots in landing configuration, the Arcus operates in a flight envelope typical of high-performance sailplanes but with the added versatility of powered self-launch.

SkyMeter has tracked flights across airframes and operators over routes, with the largest observed operator.
