Schempp-Hirth Arcus (S10S)
ICAO S10S Light Piston

Schempp-Hirth Arcus

Single Piston

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 7 flights across 3 airframes and 1 operators over routes, with the largest observed operator.

Safety in context

The incident rate counts flights with ANY safety event detected by SkyMeter: go-arounds (a routine response, not a failure), unstable-approach gate flags (advisory thresholds), rejected takeoffs (the system working as designed), and runway events. It is NOT an accident rate or fatality rate. For accident statistics, refer to the NTSB Aviation Accident Database (USA) or the Aviation Safety Network. See methodology for what each event type measures.
