Aircraft display systems and methods for enhanced display of flight path information

1. A display system for a vehicle, comprising:

a processing unit configured to receive data representative of flight path information and terrain and to supply display commands associated with the flight path information and the terrain; and

a display device coupled the processing unit and configured to receive the display commands and operable to render a three-dimensional view, including symbology representing the flight path information on the terrain, wherein the flight path information is conformal to the terrain, wherein the processing unit is further configured to receive data representative of required navigation performance information and to supply display commands associated with the required navigation performance information, and wherein the display device is further configured to render the required navigation performance information, and wherein the required navigation performance information includes first and second boundary lines, and

wherein the processing unit is further configured to issue a warning if the vehicle is operating in a position outside of the first and second boundary lines.

2. The display system of claim 1 , wherein the flight path information includes a line that traces a flight path to a destination.

3. The display system of claim 1 , wherein the flight path information is selectively rendered based on at least one of pilot input, mode of flight, and system go around commands.

4. The display system of claim 1 , wherein the flight path information includes at least two segments rendered in different colors.

5. The display system of claim 1 , wherein the first boundary line is on a first side of the flight path information and the second boundary line is on a second side of the flight path information.

6. The display system of claim 1 , wherein the first and second boundary lines are modified upon a change in the required navigation performance information.

7. The display system of claim 1 , wherein the warning includes a change in color of the boundary lines.

8. The display system of claim 1 , wherein the flight path information further includes waypoints.

9. The display system of claim 1 , wherein the processing unit is further configured to receive data representative of required navigation performance lateral deviation and to supply display commands associated with the required navigation performance lateral deviation, and wherein the display device is further configured to render the required navigation performance lateral deviation.

10. A display system for a vehicle, comprising:

a processing unit configured to receive data representative of flight path information and terrain and to supply display commands associated with the flight path information and the terrain; and

a display device coupled the processing unit and configured to receive the display commands and operable to render a three-dimensional view, including symbology representing the flight path information on the terrain, wherein the flight path information is conformal to the terrain, wherein the processing unit is further configured to receive data representative of required navigation performance information and to supply display commands associated with the required navigation performance information, and wherein the display device is further configured to render the required navigation performance information, and wherein the required navigation performance information includes first and second boundary lines,

wherein the processing unit is further configured to receive data representative of required navigation performance lateral deviation and to supply display commands associated with the required navigation performance lateral deviation, and wherein the display device is further configured to render the required navigation performance lateral deviation, and

wherein the required navigation performance lateral deviation includes a scale and an arrow positioned relative to the scale to indicate a position of the aircraft relative to the required navigation performance.

11. A display system for a vehicle, comprising:

a processing unit configured to receive data representative of required navigation performance information and terrain and to supply display commands associated with the flight path information and the terrain; and

a display device coupled the processing unit and configured to receive the display commands and operable to render a three-dimensional view, including symbology representing the required navigation performance information on the terrain,

wherein the required navigation performance information includes lines that conformally trace a required navigation performance standard.

12. The display system of claim 11 , wherein the lines are modified upon a change in the required navigation performance information.

13. The display system of claim 11 , wherein the processing unit is further configured to issue a warning if the vehicle is operating in a position outside of the lines, or a current projected path or motion dynamics of the aircraft indicates that the vehicle will operate outside the lines.

14. The display system of claim 11 , wherein the processing unit is further configured to issue a warning if the vehicle is operating in a position outside of the first and second boundary lines for a predetermined amount of time.
