An optical display system for a craft navigation simulator providing a wide angle display of greater than 3:1 width/height format derived from a closed circuit television camera viewing a terrain model. A wide-angle scene viewed is divided into three or more parts at vertical boundaries all of which are off-center and folded by a first optical system into substantially square format, in which format the composite image is processed from camera tube to display tube. A second optical system reconstructs the original wide angle image. By this means, high definition of the image in the center region and, particularly, near the horizon, is maintained.
