An on-board computer for movable craft which will control various operational functions and provide the pilot with continuous navigational information. The computer continuously determines the position of the craft with respect to the earth\s surface and provides a continuous pictorial display of such position, utilizing bearing or distance information from fixed location radio navigation transmitters such as VOR, LORAN, ADF, DME or TACAN. The computer includes a microprocessor, a memory bank, and navigational charts on photographic film. The stored information in the computer may be periodically updated by replacing or renewing the information in the memory bank and replacing the film. The apparatus may include provision for read-out of ground speed, time to destination, bearing and distance to a navigation station, way station, or destination.
