CS 22.411  Control system stiffness and stretch

ED Decision 2003/13/RM

(a)     The amount of movement available to the pilot of any aerodynamic control surface may not, in any condition of flight, be excessively reduced by elastic stretch of the control circuits.

If there are cables in the system and tension can be adjusted, the minimum value must be used for demonstrating compliance with all appropriate requirements.

(b)     For cable operated systems, the allowable rigging tension in the cables must be established, taking into consideration the variations in temperature (see CS 22.689) which may occur.
