The Victor had fully powered flying controls, i.e. ailerons, elevators and rudder, with no manual reversion which, therefore, required a back-up system, i.e. duplication. Since they were fully powered an artificial feel unit was needed, fed by ram air from the pitot in the nose. The control system was duplicated in flying control units which received pilot and autopilot demands. Pilot control movements were transmitted via a low-friction mechanical system to the flying control units. Duplication was provided on the premise that the single pilots input would remain functional and that neither hydraulic motors nor screwjack on a unit would jam. A separate hydraulic circuit was used for each of the following: landing gear, flaps, nose flaps, air brakes, bomb doors, wheel brakes, nose-wheel steering, ram-air-turbine air scoops. An AC electrical system and auxiliary power unit were significant additions to the later Victor B.2, electrical reliability being noticeably improved.
