摘要： A lap top navigation instrument, suitable for aircraft, includes a chart compartment covered by a transparent window containing a liquid crystal display as part of the window through which a conventional map or chart in the compartment can be viewed and a computer whereby an image can be generated in the display above the chart in the compartment and, through inputs to the computer from the aircraft's instruments, the computer generated image in the display will be continuously repositioned above the surface of the chart so as pilot using the device has a continuous visual indication of the position of his aircraft over the topography depicted on the chart in the compartment. Directional components may be added to the image giving the pilot additional information in reference to the heading of the aircraft relative to the chart's display of "North" showing how the image is actually tracking over the chart in the compartment. Further, in this device, the chart in the compartment is always visible to the pilot though the window. Should the instrument fail a pilot continues to have access to all the flight information contained on the chart without interruption. As a result, the instrument is very useful for instrument flight rules [IFR] procedures and instrument approaches for landings in that it is failsafe.
