Abstract:
An avionics system comprising:an FMS computer; a display coupled with said FMS computer for displaying FMS information including a graphical depiction of a flight plan, said flight plan including a first waypoint, a second waypoint, and a third waypoint, wherein the first and second waypoints are connected by a first preexisting flight leg and the second and third waypoints are connected by a second preexisting flight leg; a cursor controller, for controlling a cursor shown on said display, said cursor controller coupled with said FMS computer and said display; a potential waypoint displayed on said display as a spatial point; and said potential waypoint coupled to said FMS computer through a graphical user interface, such that a selection of said potential waypoint results in a generation, by a processor, and a display of a first possible flight leg and a second possible flight leg if a user-selected position of the cursor is nearer to the first preexisting flight leg than to the second preexisting flight leg, wherein the first possible flight leg extends between the first waypoint and the potential waypoint, and the second possible flight leg extends between the potential waypoint and the second waypoint, and a third possible flight leg and a fourth possible flight leg if the user-selected position of the cursor is nearer to the second preexisting flight leg than to the first preexisting flight leg, wherein the third possible flight leg extends between the second waypoint and the potential waypoint, and the fourth possible flight leg extends between the potential waypoint and the third waypoint.
