The moment generated by the mass is arranged to reach an equilibrium condition with the pitch control forces at each flight condition, with the flaps moving to a high lift coefficient position at low speeds or when there is a high pitch control load, and vice versa, maintaining the optimum angle of attack for the aerofoil.

The automatic flap system's suitability for cross-country flying has also been tested successfully in a specially modified Rolladen-Schneider LS3 high-performance competition glider.

Due to the automatic nature of the system, incorrect flap settings, such as caused by pilots under stress, are a thing of the past.

This aircraft has nearly 4,000 take-offs and more than 1,000 flying hours under its belt, appearing at numerous national and international competitions, flown by pilots from different countries, in Germany, Hungary, Austria, Switzerland, France, Turkey, Belgium and the Netherlands, with only about 5% of flights in the log book from the Akaflieg München home base at Königsdorf.
