Club Libelle

The Glasflügel H-201 Standard Libelle proved immensely popular, but was not an optimal aircraft for club and rental use, due to its mid-wing and low tail which could both be damaged in off-airport landings. Also its small cockpit fits only a certain demographic percentage of soaring pilots. The company developed the 205 with the design goals of a simple, rugged aircraft that would withstand club and fixed-base operator rental use. The resulting aircraft has a high-wing and a T-tail to provide more obstacle clearance as well as a larger cockpit. To eliminate gear-up landings the monowheel landing gear is non-retractable,[1][2] although at least one Club Libelle exists (D-2468 - s/n 114) which is equipped with retractable landing gear.

The aircraft is constructed from fibreglass. It has a new wing that uses a double-taper planform and incorporates combination spoilers and flaps that occupy two thirds of the wing's trailing edge. The 15.0 m (49.2 ft) span wing employs a Wortmann FX 66-17A II 182 airfoil, the same as is used on the Standard Libelle and the Glasflügel 206 Hornet.[1][2][3]

The Club Libelle was type certified in Germany as well as in the United States. The US certification was granted on 8 September 1975 and includes aerobatic approval for spins, loops, hammerhead turns and lazy eights. Due to its fibreglass construction, the aircraft's certification contains the restriction: "All external portions of the glider exposed to sunlight must be painted white. Registration and competition numbers must be painted blue-gray or in any other light color."[4]

Operational history

In July 2011 there were six 205s on the United States Federal Aviation Administration registry.[5]
