Abstract
Control apparatus, for example a thrust demand unit or "throttle box" for an aircraft, comprises a manually movable control grip coupled to drive motor means comprising twin magnetically interactive components and operable for automatic movement of the control grip, e.g. under autopilot control, while allowing override by the operator e.g. the pilot of an aircraft. The drive motor may be a linear motor, particularly a motor comprising a rod and rider each having pole teeth defining relative positions of minimum magnetic reluctance between the rod and rider, and winding means for moving the rider stepwise between said positions.
