Flying controls

THE A300B employs fully powered flying controls, operated by hydraulic power, with no reversion to manual control. The hydraulic power supplies are ‘triplexed’ to the banks of three jacks at each primary control surface. Jack sizes are chosen so that full control over the flight envelope is available with only two hydraulic systems working. Should a further system have to be shut down for any reason, the one remaining set of jacks will still provide sufficient power for control of the aircraft, including landing.
