About the Schempp-Hirth Arcus

The Schempp-Hirth Arcus is a German-built high-performance two-seat sailplane that bridges pure gliding and self-launch capability through an optional retractable sustainer engine. Introduced in 2001 by the venerable Schempp-Hirth firm (makers of competition gliders since 1935), the Arcus was designed for cross-country soaring, advanced training, and the unique European tradition of touring sailplanes where pilots fly hundreds of kilometers ridge-running and thermaling with a companion. Its 20-meter wingspan and sleek composite fuselage deliver a glide ratio exceeding 45:1, among the best in the two-seat class, while the fold-away Solo 2625 engine (when fitted) provides self-launch to 10,000 feet and climb-out from marginal fields without ground crew or towplane.

What sets the Arcus apart is its dual mission: it competes as a pure glider in the Racing Class yet offers the safety and flexibility of power when weather turns or thermals die. The cockpit seats instructor and student (or two touring pilots) in tandem under a long bubble canopy with exceptional visibility. Wing-mounted water ballast tanks allow pilots to optimize wing loading for conditions: dumping water for light-lift days or filling to 1,653 pounds MTOW for fast cruise in strong thermals. The type has become popular in North American soaring clubs and among private owners who value the ability to operate from remote grass strips without external support.

The Arcus remains in production at Schempp-Hirth's Kirchheim facility, with increments like the Arcus M (shorter 18-meter span for tighter thermals) and the Arcus T (turbocharged sustainer) expanding the family. Its operating envelope (never-exceed speed of 168 knots, stall around 43 knots with flaps) reflects the sailplane's lightweight structure and long wings, demanding smooth handling and respect for turbulence limits. SkyMeter has tracked flights across airframes and operators, with the largest observed operator.
