The invention provides a primary flight display instrument in which a symbolsuch
as a small star or triangleindicates 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.
