AbstractAn indicator system satisfies multiple flight-mission requirements by providing an aircraft pilot with a visual display consisting of a movable map and navigational data. The map is stored in video form in a high-capacity compact mass memory consisting of a video disk. The system further comprises a symbol and character generator as well as an intermediate memory which has a capacity larger than required for the map-zone image to be displayed together with navigation symbols on a television monitor. The unit is controlled by a microprocessor on the basis of data relating to latitude, longitude and heading of the aircraft in order to refresh the intermediate memory and to obtain an image displayed with a "top-north" or "top-heading" orientation.
