ASK 23 GliderSchleicher ASK 23

The ASK 23 glider is an excellent training glider. This is the first single seat glider that most new solo students transition to from the two place ASK 21 trainer.

Pilot Approval Requirements: The pilot must have sign off by an instructor and must meet Williams Soaring Operating Policy and Insurance requirements - See Pilot Information Section.

The Schleicher ASK 23 is a single-seat Club Class sailplane that was built by the German manufacturer Alexander Schleicher GmbH & Co. It was the last glider to be designed by Rudolf Kaiser. It is an early solo sailplane with docile handling, and so it was a successor to the Schleicher Ka 8 and ASK 18. It is also the single-seater counterpart of the two-seater Schleicher ASK 21 with a similar cockpit layout.

It uses glass-fibre reinforced plastic and 'honeycomb' as its main constructional materials. It has no flaps, a fixed nose wheel, a fixed main-wheel and a tail wheel. The first ASK 23 flew in October 1983.
