A Stability and Control Augmentation System ("SCAS") module includes a SCAS actuator (610). The SCAS actuator (610) has a substantially cylindrical hydraulic chamber having a first and second regions (620, 625). A piston (630) is arranged for linear motion in first and second directions along an axis of the hydraulic chamber. The SCAS module (600) also includes a valve system (635) for controlling a flow of a hydraulic fluid into the hydraulic chamber. The valve system (635) has: at least one supply line (672) arranged to provide a first fluid flow path to the first region (620) of the hydraulic chamber and/or a second fluid flow path to the second region (625) of the hydraulic chamber, and a moveable valve member (660) arranged to have a position between a first and second positions.
