Abstract

A method of displaying flight management system (FMS) data, and an avionics system configured to implement the method, are provided. The method includes the step of providing FMS route data. The method also includes the step of using the FMS route data to display an FMS intent strip which represents current maneuvering intent of the FMS.

Claims

1. A method of displaying flight management system (FMS) data, the method comprising:

providing FMS route data from an FMS to a single display device; and

displaying, using the FMS route data, an FMS intent strip and a separate FMS future intent strip simultaneously on the single display device, the FMS intent strip representing to a pilot current maneuvering intent of the FMS and the separate FMS future intent strip representing to the pilot future maneuvering intent of the FMS for a next flight segment, wherein displaying the FMS intent strip comprises simultaneously displaying both a lateral navigation icon in a lateral navigation window of the FMS intent strip and a vertical navigation icon in a vertical navigation window of the FMS intent strip on the single display device, the lateral navigation icon in the FMS intent strip graphically representing current lateral maneuvering intent of the FMS and the vertical navigation icon in the FMS intent strip graphically representing current vertical maneuvering intent of the FMS, wherein displaying the FMS future intent strip comprises simultaneously displaying both a lateral navigation icon in a lateral navigation window of the FMS future intent strip and a vertical navigation icon in a vertical navigation window of the FMS future intent strip, the lateral navigation icon in the FMS future intent strip graphically representing future lateral maneuvering intent of the FMS for the next flight segment and the vertical navigation icon in the FMS future intent strip graphically representing future vertical maneuvering intent of the FMS for the next flight segment, and wherein displaying the FMS intent strip further comprises also simultaneously displaying, in the FMS intent strip on the single display device, FROM and TO waypoint IDs for a current flight segment, the FROM waypoint ID for the current flight segment being displayed in a separate FROM waypoint window of the FMS intent strip, and the TO waypoint for the current flight segment being displayed in a separate TO waypoint window of the FMS intent strip.

2. The method of claim 1, wherein the lateral navigation icon in the lateral navigation window of the FMS intent strip comprises an arrow which graphically represents current FMS lateral maneuvering intent to do one of turning left and turning right.

3. The method of claim 1, wherein displaying the FMS intent strip further comprises also simultaneously displaying lateral numerical data in the lateral navigation window of the FMS intent strip adjacent to the lateral navigation icon on the single display device, the lateral numerical data numerically representing current lateral maneuvering intent of the FMS.

4. The method of claim 1, wherein the vertical navigation icon in the vertical navigation window of the FMS intent strip graphically represents current FMS vertical maneuvering intent to do one of climbing, descending, leveling off, and maintaining an at constraint altitude.

5. The method of claim 1, wherein displaying the FMS intent strip further comprises also simultaneously displaying vertical numerical data in the vertical navigation window of the FMS intent strip adjacent to the vertical navigation icon on the single display device, the vertical numerical data numerically representing current vertical maneuvering intent of the FMS.

6. The method of claim 1, wherein displaying the FMS intent strip further comprises also simultaneously displaying, in the FMS intent strip on the single display device, time and distance from the TO waypoint of the current flight segment.

7. The method of claim 1, and further comprising also simultaneously displaying on the single display device a map adjacent the FMS intent strip and the FMS future intent strip.

8. An avionics system comprising:

a source of flight management system (FMS) data; and

a single display device configured to display an FMS intent strip, using the FMS data, which represents current maneuvering intent of the FMS for a current flight segment between a current FROM waypoint and a TO waypoint, wherein the single display device is configured to display the FMS intent strip by simultaneously displaying lateral and vertical navigation icons, in the FMS intent strip, which respectively graphically represent current lateral and vertical maneuvering intent of the FMS for the current flight segment, wherein the single display device is configured to simultaneously display in a lateral navigation window of the FMS intent strip both the lateral navigation icon and lateral numeric data which numerically represents current lateral maneuvering intent of the FMS, wherein the lateral navigation icon in the lateral navigation window of the FMS intent strip comprises an arrow which graphically represents current FMS lateral maneuvering intent to do one of turning left and turning right, and wherein the single display device is configured to simultaneously display in a separate vertical navigation window of the FMS intent strip both the vertical navigation icon and vertical numeric data which numerically represents current vertical maneuvering intent of the FMS, wherein the single display device is further configured to simultaneously display along with the FMS intent strip an FMS future intent strip, using the FMS data, which represents future maneuvering intent of the FMS for a next flight segment, wherein the single display device is configured to simultaneously display lateral and vertical navigation icons, respectively in lateral and vertical navigation windows of the FMS future intent strip, which respectively graphically represent future lateral and vertical maneuvering intent of the FMS for the next flight segment, wherein the display device is also configured to simultaneously display lateral and vertical numerical data, respectively in the lateral and vertical navigation windows of the FMS future intent strip, which numerically represent future lateral and vertical maneuvering intent of the FMS for the next flight segment.

9. The avionics system of claim 8, wherein the FMS intent strip and the FMS future intent strip simultaneously include FROM and TO waypoint IDs, respectively, for the current and next flight segments displayed on the single display device.

10. The avionics system of claim 9, wherein the FMS intent strip further simultaneously includes time and distance from the TO waypoint of the current flight segment, and wherein the FMS future intent strip further simultaneously includes time and distance between the FROM waypoint and the TO waypoint of the next flight segment.
