Abstract

A system and method displays a synthetic vision system (SVS) image combined with a primary flight display (PFD) including a compass indicating the aircraft heading. An arc on or near the outer edge of the compass indicates the viewing frustum of the SVS view.

First claim

What is claimed is:

1 . A display system for an aircraft comprising:
a display; an avionics system; a synthetic vision system; and a processor coupled to the display, avionics system, and synthetic vision system, the processor configured to:
ascertain flight parameters of the aircraft from the avionics system, the flight parameters including a heading;
ascertain a view from the aircraft from the synthetic vision system, the view comprising a horizontal span;
provide commands to the display to display the view;
provide commands to the display to display a compass including a first index indicating the heading, the compass including a heading scale; and
provide commands to the display to display an arc contiguous or adjacent to a portion of the heading scale representative of the horizontal span of the synthetic vision system view being displayed.

2 . The display system of claim 1 wherein the processor is further configured to:
provide commands to the display to display a second index located at a center of the arc indicating a center point of the synthetic vision system view.

3 . The display system of claim 1 wherein the processor is further configured to:
provide commands to the display to display the arc in a first format and the circumscribed ring in a second format.

4 . The display system of claim 1 wherein the processor is further configured to:
provide commands to the display wherein the arc is moved in relation to the heading scale as a flying condition of the aircraft changes.

5 . The display system of claim 1 wherein the processor is further configured to:
provide commands to the display to display changing a format of the arc as the difference between the heading and the view changes.

6 . The display system of claim 1 wherein the processor is further configured to:
provide commands to the display to display a first line from a center of the compass to a first end of the arc, and a second line from the center to a second end of the arc.

7 . The display system of claim 1 wherein the processor is further configured to:
provide commands to the display to display a course pointer within the compass indicating the desired ground track.

8 . A display system for an aircraft, the display system comprising:
a display; an avionics system; a synthetic vision system; and a processor coupled to the display, the avionics system, and the synthetic vision system, the processor configured to:
determine a heading of the aircraft from the avionics system;
ascertain a view from the aircraft from the synthetic vision system;
provide commands to the display to display the view;
provide commands to the display to display a compass including an index indicating the heading, the compass including a ring; and
provide commands to the display to display an arc associated with a portion of the ring, the arc representative of the horizontal span of the view being displayed.

9 . The display system of claim 8 wherein the processor is further configured to:
provide commands to the display wherein the arc is moved in relation to the ring as a heading of the aircraft changes.

10 . The display system of claim 8 wherein the processor is further configured to:
provide commands to the display to display changing a format of the arc as the difference between the heading and the view changes.

11 . The display system of claim 8 wherein the processor is further configured to:
provide commands to the display to display a course pointer within the compass indicating the desired ground track.

12 . A method of providing visual guidance for maneuvering an aircraft, comprising:
ascertaining via a processor a synthetic vision system view from the aircraft, the synthetic vision system view comprising a horizontal span; determining via the processor a heading of the aircraft; displaying via the processor on a display a compass including an index indicating the heading, the compass including a ring; displaying the synthetic vision system view; and displaying an arc contiguous to a portion of the circumscribed ring representative of the horizontal span of the synthetic vision system view being displayed.

13 . The method of claim 12 wherein the arc is touching the ring of the compass.

14 . The method of claim 12 wherein the arc is spaced from the circumscribed ring of the compass.

15 . The method of claim 12 further comprising an index located at a center of the arc indicating a center point of the synthetic vision system view.

16 . The method of claim 12 wherein the arc comprises a first format and the circumscribed ring comprises a second format.

17 . The method of claim 12 wherein the arc is moved in relation to the circumscribed ring as a heading of the aircraft changes.

18 . The method of claim 12 further comprising changing a format of the arc as the difference between the heading and the synthetic vision system view changes.

19 . The method of claim 12 further comprising displaying a first line from a center of the compass to a first end of the arc, and a second line from the center to a second end of the arc.

20 . The method of claim 12 further comprising a course pointer within the compass indicating a desired ground track.
