ABSTRACT OF THE DISCLOSURE Visual display apparatus for ground-based craft flight simulation apparatus using a raster scan display for viewing by the trainee pilot and providing an image comprising a target or other craft, together with cloud extending to the simulated horizon. The cloud image part has repetitively patterned features and is displayed in correct perspective, according to the simulated flight position relatively thereto, for providing speed and altitude cues. This part of the image is provided by digital means, a single cycle of the repetitive pattern being held in a digital store and perspective being computed continuously. The whole apparatus includes three generators providing respectively sky, horizon and patterned cloud surface all controlled by a general purpose computer receiving flight data from the simulator flight computer. Outputs from the three generators are selected appropriately during the raster scan of the display and also appropriately combined with a high- definition image of the target or other craft.
