INSTRUMENT REFERENCE FLIGHT DISPLAY SYSTEM FOR HORIZON REPRESENTATION OF DIRECTION TO NEXT WAYPOINT

The invention provides a primary flight display instrument in which a symbol—such as a small star or triangle—indicates the bearing to the current waypoint in the flight navigation plan. The display may also show a bearing indication symbol showing a follow-on waypoint in the flight plan. These symbols are preferably located on the horizon line of the primary flight display (or the attitude indicator) providing bearing to the current waypoint in the flight plan and/or to the following waypoint. An image processing unit generates the display, including earth ground and horizon, in a view substantially conformal with a VMC view from the aircraft.
