Abstract : Two concepts, the vector reticle and control action display, are submitted as effective means for making manual threeaxis attitude control quicker and more efficient while reducing substantially the concentration required of the pilot. A system design is submitted in which the two concepts are combined in a control action reticle and in which the pilot has direct control of the jet valves. (The entire system may be mechanical.) The system is controlled to a visual reference or to an instrument attitude reference. Malfunction of the system cannot interfere with normal manual control. The vector recticle presents all auxiliary information in a single three-part geometric vector superimposed on the window (rather than on three separate dials, for example), thus reducing the number of quantities to be monitored from three to one. Control action display gives the pilot instantaneous and exclusive control of the reticle, thus removing the need for two mental integrations and greatly reducing the concentration required for tracking. Results are presented of three-axis (fixed-base) simulation studies of the proposed system and of other systems for comparison. (Author)
