AbstractA display for an aircraft simulator that produces an image of an air strip or the like that is accurate in color and in relative light intensity. A television camera supported over a terrain model that simulates an aircraft landing zone, a full spectrum color monitor connected to the camera and lens system for projecting the monitor image onto a lens or screen visually accessible to a trainee in the simulator. The camera is supported on a gantry frame and is movable in six degrees of freedom. There is a control yoke and like simulated aircraft controls accessible to the trainee the outputs of which are linked to the gantry frame. A monochromatic calligraphic display, a digital computer for producing a pattern on the display that corresponds to the lights associated with the landing strip on the terrain model and an optical system for projecting the calligraphic image onto the same lens so that it is superposed on the video representation on the landing field. The optical system includes a four-color wheel which is rotated between the calligraphic display and the lens, and apparatus for synchronizing the generation of a calligraphic pattern with the different color segments on the color wheel. A servo feedback system responsive to the position and velocity of the servo motors on the gantry frame for producing an input to the computer so that the calligraphically generated signal corresponds in shape, size and location to the video signal.
