Abstract

A present novel and non-trivial system, apparatus, and method is disclosed for presenting a flight director-dependent highway in the sky (“HITS”) pathway on an aircraft display unit. A processor receives flight plan data and flight director data, generates HITS data set representative of a flight director-dependent HITS pathway using flight plan data and flight director data, and provides the HITS data set to a display system for presentation of the flight director-dependent HITS pathway on a tactical display unit. Flight plan data provided to the processor may comprise of data sourced by a navigation system or HITS pathway data generated independently of flight director data. When presented on a tactical display unit, the flight director-dependent HITS pathway may be depicted with the flight director, where the proximal end of the HITS pathway aligns with the flight director.

First claim

What is claimed is:

1. A system for presenting a flight director-dependent highway-in-the-sky pathway on a tactical display unit, such system comprising:
a source of flight mode data;
a source of flight plan data;
a source of flight director data;
a processor configured to
receive flight plan data,
receive flight director data representative of a change of at least vertical guidance, where
the change of vertical guidance is made in response to a manual change of a vertical mode parameter,

generate an image data set representative of
a first image of a flight director symbology, and
a second image of a highway-in-the-sky pathway, wherein
the second image is comprised of a proximal end and a distal end,
the location of the proximal end of the second image is
dependent upon the location of the first image, and
aligned vertically with the first image, and

the location of the distal end of the second image is
based upon the flight plan data, and
dependent upon the path of the flight plan, and

provide the image data set to an aircraft display system; and

the aircraft display system configured to
receive the image data set, and
display the first image and the second image, whereby
the first image moves vertically in response to the manual change of a vertical mode parameter,
the proximal end of the second image moves vertically in response to vertical movement of the first image, and
the vertical alignment of the second image is maintained with the first image during the vertical movements of the first image and the second image.

2. The system of claim 1 , where the source of flight mode data is a pilot interface system.

3. The system of claim 2 , where the pilot interface system is comprised of a flight control panel.

4. The system of claim 1 , where the flight mode data is comprised of data representative of a vertical flight mode, lateral flight mode, or both.

5. The system of claim 1 , where the source of flight plan data is a flight management system.

6. The system of claim 1 , where the flight plan data is comprised of data representative of a vertical flight plan, lateral flight plan, or both.

7. The system of claim 1 , where the source of flight director data is a flight director system.

8. The system of claim 1 , where the flight director data is further representative of a change of lateral guidance.

9. The system of claim 1 , wherein the processor is incorporated into an existing avionics system.

10. The system of claim 9 , wherein the existing avionics system includes a flight management system, a flight director system, or the aircraft display system.

11. The system of claim 1 , where the flight plan data received by the processor is comprised of data representative of a highway-in-the-sky pathway generated independently of the flight director data.

12. A module for presenting a flight director-dependent highway-in-the-sky pathway, such module comprising:
an input communications interface to facilitate the receiving of data from at least one data source by a processor;
the processor configured to
receive flight plan data,
receive flight director data representative of a change of at least vertical guidance, where
the change of vertical guidance is made in response to a manual change of a vertical mode parameter,

generate an image data set representative of
a first image of a flight director symbology, and
a second image of a highway-in-the-sky pathway, wherein
the second image is comprised of a proximal end and a distal end,
the location of the proximal end of the second image is
dependent upon the location of the first image, and
aligned vertically with the first image, and

the location of the distal end of the second image is
based upon the flight plan data, and
dependent upon the path of the flight plan, and

provide the image data set to an aircraft display system, such that
the first image and the second image are displayed, whereby
the first image moves vertically in response to the manual change of a vertical mode parameter,
the proximal end of the second image moves vertically in response to vertical movement of the first image, and
the vertical alignment of the second image is maintained with the first image during the vertical movements of the first image and the second image; and

an output communications interface to facilitate the providing of the image data set to the aircraft display system.

13. The module of claim 12 , wherein the module is incorporated into an existing avionics system.

14. The module of claim 13 , wherein the existing avionics system includes a flight management system, a flight director system, or the aircraft display system.

15. The module of claim 12 , where the flight plan data received by the processor is comprised of data representative of a highway-in-the-sky pathway generated independently of flight director data.

16. A method for presenting a flight director-dependent highway-in-the-sky pathway, such method comprising:
performing the following elements, where such elements are performed by an aircraft avionics system processor:
receiving flight plan data;
receiving flight director data representative of a change of at least vertical guidance, where
the change of vertical guidance is made in response to a manual change of a vertical mode parameter;

generating an image data set representative of
a first image of a flight director symbology, and
a second image of a highway-in-the-sky pathway, wherein
the second image is comprised of a proximal end and a distal end,
the location of the proximal end of the second image is
dependent upon the location of the first image, and
aligned vertically with the first image, and
