About the Schleicher ASW 29

The Schleicher ASW 29 is a high-performance racing sailplane that represents the pinnacle of modern glider design for Open Class competition. Introduced in 2005 by the German manufacturer Alexander Schleicher GmbH & Co, the ASW 29 features an 18-meter wingspan (extendable to 20 meters with optional wingtip extensions) and advanced aerodynamics that deliver exceptional climb rates in thermals and outstanding cross-country speed. Its carbon fiber construction keeps empty weight around 570 pounds while maintaining structural strength for the demanding loads of competitive soaring.

The type quickly established itself as a dominant force in international gliding competitions, with pilots achieving multiple world records for speed over distance. The ASW 29 excels in weak lift conditions where its efficient wing design and low sink rate provide a decisive advantage, yet it remains fast enough in strong conditions to compete with pure racing machines. Maximum glide ratio exceeds 50:1 under optimal conditions, meaning the aircraft can travel more than 50 feet forward for every foot of altitude lost. The cockpit accommodates pilots up to 6'5" and features modern instrumentation including GPS-based flight computers and variometers that display real-time thermal strength.

Despite having no engine, the ASW 29 routinely achieves cross-country flights exceeding 500 miles by exploiting atmospheric lift from thermals, ridge lift, and wave systems. The never-exceed speed of 155 knots allows aggressive flying in strong conditions, while the clean stall speed of 43 knots provides a wide speed envelope for tactical racing. Water ballast tanks allow pilots to increase wing loading for faster cruise speeds on strong days, then dump the ballast for better climb performance as conditions weaken. SkyMeter has tracked flights across airframes and operators, with the largest observed operator.
