Re post 1351

IIRC, the PFCU's were indeed electrically powered, as Beags says, but the motor drove a hydraulic pump in a self - contained hydraulic system. If no command was present, the pump was idling, off- loading the motor. When a control input was made, the pump started to deliver hydraulic power which was directed to give the required movement of the control.
So, "electrically powered, hydraulically actuated".
