The Windward Performance SparrowHawk is an American mid-wing, single-seat glider that was designed and produced by Windward Performance.[2]

Since 2016 the aircraft has been no longer advertised as available by the manufacturer.[3]

Design and development

The SparrowHawk was designed to fit into the US FAR 103 Ultralight Vehicles category, including that category's requirement that unpowered aircraft have a maximum empty weight of {{convert|155|lb|kg|0|abbr=on}}. The sailplane achieves this by utilizing a structure that is predominantly made from carbon-fiber-reinforced polymer.[2][4]

The SparrowHawk's multi-tapered, {{convert|36.1|ft|m|1|abbr=on}} span wing employs five different airfoils and has an aspect ratio of 18.6:1. The wing features Schempp-Hirth style spoilers on the top surface. The cockpit can accommodate pilots who range in height from {{convert|63|to|75|in|cm|0|abbr=on}}. The landing gear is a fixed monowheel gear with an auxiliary tail wheel. The glider is finished with a two part polyurethane paint. The aircraft can be launched by auto-tow, winch-launch, or aero-tow by both light aircraft and ultralight aircraft. Aerobatics are not recommended.[2][4]

The SparrowHawk achieves a best glide ratio of 36:1 and a minimum sink rate of 119 ft/min (0.60 m/s).[5]
