CS 22.725  Level landing

CAA ORS9 Decision No. 1

(a) The shock absorbing elements (including tyres) must be capable of absorbing the kinetic energy developed in a landing without being fully depressed. 

(b) The value of kinetic energy must be determined under the assumption that the weight of the sailplane corresponds to the design maximum weight with a constant rate of descent equalling the value given in CS 22.473(b) and the wing lift balancing the weight of the sailplane. 

(c) Under the assumption of (b) the c.g. acceleration must not exceed 4.5 g.
