About the Schempp-Hirth Arcus

The Schempp-Hirth Arcus is a German-built high-performance two-seat sailplane that bridges the gap between pure gliders and self-launching motor gliders. Introduced in the mid-2000s, the Arcus features a retractable sustainer engine, typically a small piston powerplant that extends for self-launch or to reach thermal-rich airspace, then retracts flush into the fuselage to preserve the aircraft's exceptional glide performance. With a wingspan of 20 meters and a best glide ratio exceeding 45:1, the Arcus competes at the top tier of the FAI 20-meter two-seat class, combining cross-country speed with the safety and training advantages of dual controls.

The type is popular among soaring clubs and private owners who value the flexibility of engine-assisted departures without sacrificing the purity of soaring flight once airborne. Its composite construction, sleek lines, and sophisticated wing design make it a frequent sight at gliding competitions across Europe and North America. SkyMeter has tracked flights across airframes and operators, with the largest observed operator.
