ICAO S12 Light Piston

Schempp-Hirth Arcus

Single Piston

The Schempp-Hirth Arcus is a German-built side-by-side two-seat sailplane that represents the pinnacle of modern high-performance glider design. Introduced in 2009, the Arcus combines exceptional soaring capability with the practicality of a retractable sustainer engine, allowing pilots to self-launch or extend cross-country flights without relying on towplanes or thermals. With an 20-meter wingspan and advanced laminar-flow airfoil, the Arcus achieves glide ratios exceeding 50:1, making it one of the most efficient sailplanes in its class. The side-by-side seating configuration is unusual for high-performance gliders and makes it particularly popular for training, cross-country racing, and shared soaring experiences. The optional Solo 2625 two-stroke engine retracts fully into the fuselage behind the cockpit, preserving the aircraft's clean aerodynamic lines when soaring. The Arcus has become a favorite in European soaring clubs and among serious cross-country pilots who value both performance and versatility. SkyMeter has tracked 1 flights across 1 airframes and 1 operators, with distinct routes observed.

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.
