Abstract

A method for providing a display to a flight crew of an aircraft includes the steps of providing a synthetic image comprising a first field of view forward of a direction of travel of the aircraft and providing a sensory image overlaying at least a first portion of the synthetic image. The sensory image includes a second field of view forward of the direction of travel of the aircraft. At least a portion of the first field of view and a portion of the second field of view overlap one another. The sensory image is centered within the synthetic image with respect to a horizontal axis. The method further includes moving the sensory image so as to overlay at least a second portion of the synthetic image such that the sensory image is no longer centered with respect to the horizontal axis within the synthetic image.

Claims

1. A method for providing a display to a flight crew of an aircraft comprising the steps of:

providing a synthetic image comprising a first field of view forward of a direction of travel of the aircraft;

providing a sensory image overlaying a first portion of the synthetic image, the sensory image comprising a second field of view forward of the direction of travel of the aircraft, wherein at least a portion of the first field of view and the second field of view overlap one another, and wherein the sensory image is centered within the synthetic image with respect to a horizontal axis; and

moving the sensory image so as to comprise a third field of view forward of the direction of travel of the aircraft and so as to overlay a second portion of the synthetic image such that the sensory image is no longer centered with respect to the horizontal axis within the synthetic image, wherein at least a portion of the first field of view and the third field of view overlap one another.

2. The method of claim 1, wherein the second field of view and the third field of view at least partially overlap one another.

3. The method of claim 1, further comprising providing a flight path vector, and wherein the third field of view is centered over the flight path vector with respect to the horizontal axis.

4. The method of claim 3, wherein the third field of view is further centered over the flight path vector with respect to a vertical axis.

5. The method of claim 1, wherein moving the sensory image further comprises rotating the sensory image clockwise or counterclockwise.

6. The method of claim 5, wherein rotating the sensory image comprises rotating the sensory image to correspond with a horizon during an aircraft banking maneuver.

7. The method of claim 1, wherein moving the sensory image further comprises at least one of increasing a size of the sensory image and decreasing a size of the sensory image.

8. The method of claim 7, wherein increasing the size of the sensory image is performed as a runway toward which the aircraft is flying increases in size within the third field of view.

9. The method of claim 1, wherein moving the sensory image comprises moving the sensory image toward an intruding aircraft target, a position of the intruding aircraft target being determined by a traffic alert and avoidance system of the aircraft.

10. The method of claim 1, wherein moving the sensory image comprises moving the sensory image toward an obstacle in a flight path of the aircraft, a position of the obstacle being determined by an obstacle alert and avoidance system of the aircraft.

11. A display system configured to provide a display to a flight crew of an aircraft comprising:

an image sensor;

an image display device;

a data storage device that stores navigation information and runway information; and

a computer processor device, wherein the computer processor device is configured to;

generate for display on the image display device a synthetic image comprising a first field of view forward of a direction of travel of the aircraft based at least in part on the navigation information and the runway information;

receive for display on the image display device and from the image sensor a sensory image and display the sensory image overlaying a first portion of the synthetic image, the sensory image comprising a second field of view forward of the direction of travel of the aircraft, wherein at least a portion of the first field of view and the second field of view overlap one another, and wherein the sensory image is centered within the synthetic image with respect to a horizontal axis; and

receive for display on the image display device and from the image sensor a further sensory image comprising a third field of view forward of the direction of travel of the aircraft and move the sensory image so as to overlay a second portion of the synthetic image such that the sensory image is no longer centered with respect to the horizontal axis within the synthetic image, wherein at least a portion of the first field of view and the third field of view overlap one another.

12. The system of claim 11, further comprising an aircraft position detecting system, wherein the synthetic image is generated and displayed further based at least in part on an aircraft position as detected by the aircraft position detecting system.

13. The system of claim 12, wherein the aircraft position detecting system is a GPS system.

14. The system of claim 11, wherein the image sensor is a millimeter wave radar system.

15. The system of claim 11, wherein the image sensor is a forward looking infrared camera.

16. The system of claim 11, wherein a directional configuration of the image sensory is adjustable to capture the third field of view.

17. A method for providing a display to a flight crew of an aircraft comprising the steps of:

while the aircraft is descending but prior to reaching a first predetermined position;

providing a first synthetic image comprising a first field of view forward of a direction of travel of the aircraft; and

providing a first sensory image overlaying a first portion of the first synthetic image, the first sensory image comprising a second field of view forward of the direction of travel of the aircraft, wherein at least a portion of the first field of view and the second field of view overlap one another, and wherein the first sensory image is centered within the first synthetic image with respect to a horizontal axis;

while the aircraft is descending and after reaching the first predetermined position but prior to reaching a second predetermined position;

providing a second synthetic image comprising the first field of view forward of the direction of travel of the aircraft; and

providing a second sensory image overlaying a first portion of the second synthetic image, the second sensory image comprising a third field of view forward of the direction of travel of the aircraft, wherein at least a portion of the first field of view and the third field of view overlap one another, and wherein the second sensory image is centered on a flight path vector with respect to the horizontal axis; and

while the aircraft is descending and after reaching the second predetermined position but prior to reaching a runway;

providing a third synthetic image comprising the first field of view forward of the direction of travel of the aircraft and the runway; and

providing a third sensory image overlaying a first portion of the third synthetic image, the third sensory image comprising a third field of view forward of the direction of travel of the aircraft and the runway, wherein at least a portion of the first field of view and the third field of view overlap one another, and

wherein the third sensory image is centered on a touchdown zone of the runway with respect to the horizontal axis.

18. The method of claim 17, wherein the first predetermined position is an initial approach fix and the second predetermined position is a final approach fix.

19. The method of claim 17, wherein the third sensory image is larger than the second sensory image and larger than the first sensory image, the sensory image sizes being dependent upon or a function of a position of aircraft on a glideslope, including a distance and altitude to a runway.

20. The method claim 17, further comprising:

detecting an intruding aircraft using a traffic collision avoidance system; and

while providing either the first, second, or third synthetic image;

providing a fourth sensory image overlaying a first portion of either the first, second, or third synthetic image, the fourth sensory image comprising a fourth field of view forward of the direction of travel of the aircraft, wherein at least a portion of the first field of view and the fourth field of view overlap one another, and wherein the fourth sensory image is centered on a the intruding aircraft with respect to the horizontal axis.
