Schempp-Hirth Standard Austria
The Standard Austria was a single-seat aerobatic glider that was originally designed and built in Austria from 1959 but production was moved in 1962 to Schempp-Hirth in Germany.
== Development ==
Commissioned by the ''Österreichischer Aeroclub'' – (Austrian Aero club) the Standard Austria was designed by Rüdiger Kunz to compete in the 1960 OSTIV competition for a standard class sailplane, winning plaudits as the best standard class aircraft.〔http://www.sailplanedirectory.com/schempp.htm〕 The design aims were to produce an aircraft with a low wing loading and a high lift/drag ratio, which necessitated low weight and low drag. To achieve the design aims the Standard Austria was constructed primarily of wood with plywood skinning and a glass-fibre nose section, pilots seat and tail-cone. Other weight and drag saving measures included use of an all-moving 'V' or 'Butterfly' tail unit with two surfaces, set in a 'V' configuration, providing stability and control in both pitch and yaw, in exchange for increased cost and complexity of the control systems and minor handling side effects, like slight pitching of the aircraft with application of rudder and vice versa.
After the initial production run in Austria, production was moved to Schempp-Hirth in Germany, where the Standard Austria's development continued with improved and heavier models, optional retractable undercarriage, replacement of the NACA section wings with wings using an Eppler 266 section,〔 to improve low-speed performance.
Two were used in the 1967 NFB film 'Flight' (CF-RNH, CF-RSO)().
