CS 22.203  Turning flight stalls

CAA ORS9 Decision No. 1

(a) When stalled during a co-ordinated 45° banked turn, it must be possible to regain normal level flight without encountering uncontrollable rolling or spinning tendencies. Compliance with this requirement must be shown under the conditions of CS 22.201(f) that result in the most critical stall behaviour of the sailplane. In any case the landing configuration, with airbrakes retracted and extended, must be investigated.

(b) The loss of altitude from beginning of the stall until regaining level flight by applying normal procedures must be determined.
