6 JULY 1950 FLIGHT HYDRAULIC AIRCRAFT EQUIPMENT One of the greatest advances in these days of increasing speeds and size of aircraft is the "Servodyne"* system of power assistance for flying controls. By an extremely interesting design of hydraulic unit, any dead periods due to overlapping valve leads are minimised. The system is pre-loaded — eliminating slow rate deflections — and retention of the natural feel of the controls can be arranged. It is generally used in conjunction with the famous Lockheed engine- driven pump, shown above. This combination is used in the De Havilland "Comet" jet air-liner, with outstanding success.
