ABSTRACT:
A topographical map display device for a vehicle, such as an aircraft, wherein a map in miniaturized form is carried on a carriage coupled to a frame by way of a mechanism which permits translational planar movement only of the carriage with respect to the frame and an image of an area of the map is projected onto a display surface on which a fixed datum represents the vehicle position, the carriage being moved with respect to the frame by actuator means in dependence on the range and bearing of the vehicle with respect to a ground-fix position so that the image of the map projected onto the display device changes progressively with vehicle movement whilst maintaining a fixed orientation.
