Abstract

Claims (32)

1. A method for separating avionics charts into a plurality of display panels, the method comprising:

receiving chart data for one or more virtual avionics charts;

comparing a data size of the received chart data to a predetermined data size threshold to determine whether the received chart data exceeds the predetermined data size threshold;

in response to determining the received chart data exceeds the predetermined threshold, generating the plurality of display panels, wherein generating the plurality of display panels comprises:

determining one or more fold locations by removing one or more portions of the received chart data to generate an adjusted image;

determining one or more fold sizes of the adjusted image based on a folding algorithm, wherein the one or more fold sizes include an x-axis fold size and a y-axis fold size;

and assigning one or more fold numbers based on the x-axis fold size and the y-axis fold size;

determining one or more buffer lengths for the generated plurality of display panels, wherein the one or more buffer lengths have a physical length defined by at least one of a length in a x-direction or a length in a y-direction;

generating a plurality of sections by adding the one or more buffer lengths around a perimeter of each display panel of the plurality of display panels, wherein the one or more buffer lengths of the plurality of sections form one or more overlapping regions between at least a first section of the plurality of sections and a second section of the plurality of sections, wherein the second section is arranged adjacent to at least the first section;

and generating, via an offboard controller, a plurality of output files based on the generated plurality of sections.

2. The method of claim 1 , further comprising: providing the plurality of output files to an on-board aircraft controller for display on one or more display devices of an aircraft.

3. The method of claim 1 , wherein the predetermined data size threshold is between 1.2 Mb and 1.5 Mb.

4. The method of claim 3 , wherein the predetermined data size threshold is 1.3 Mb.

5. The method of claim 1 , wherein the physical length of the one or more buffer lengths is 1.00 inch.

6. The method of claim 1 , further comprising: determining whether chart data of the generated plurality of output files exceeds the predetermined threshold; and upon determining the chart data of the generated plurality of output files for the one or more display panels exceeds the predetermined threshold, adjusting a fold size of the one or more display panels.

7. A system for separating avionics charts into a plurality of display panels, comprising:

one or more controllers including one or more processors configured to execute a set of program instructions stored in a memory, the set of program instructions configured to cause the one or more processors to:

receive chart data for one or more virtual avionics charts;

compare a data size of the received chart data to a predetermined data size threshold to determine whether the received chart data exceeds the predetermined data size threshold;

in response to determining the received chart data exceeds the predetermined threshold, generate a plurality of display panels, wherein the set of program instructions are configured to cause the one or more processors to:

determine one or more fold locations by removing one or more portions of the received chart data to generate an adjusted image;

determine one or more fold sizes, wherein the one or more fold sizes include an x-axis fold size and a v-axis fold size of the adjusted image based on a folding algorithm;

and assign one or more fold numbers based on the x-axis fold size and the v-axis fold size;

determine one or more buffer lengths for the generated plurality of display panels, wherein the one or more buffer lengths have a physical length defined by at least one of a length in a x-direction or a length in a y-direction;

generate a plurality of sections by adding the one or more buffer lengths around a perimeter of each display panel of the plurality of display panels, wherein the one or more buffer lengths of the plurality of sections form one or more overlapping regions between at least a first section of the plurality of sections and a second section of the plurality of sections, wherein the second section is arranged adjacent to at least the first section;

and generate a plurality of output files based on the generated plurality of sections.

8. The system of claim 7 , wherein the one or more controllers are further configured to: provide the plurality of output files to an on-board aircraft controller for display on one or more display devices of an aircraft.

9. The system of claim 7 , wherein the predetermined data size threshold is between 1.2 Mb and 1.5 Mb.

10. The system of claim 9 , wherein the predetermined data size threshold is 1.3 Mb.

11. The system of claim 7 , wherein the controller is further configured to: determine whether chart data of the generated plurality of output files exceeds the predetermined threshold; and upon determining the chart data of the generated plurality of output files for the one or more display panels exceeds the predetermined threshold, adjusting a fold size of the one or more display panels.

12. The method of claim 1 , wherein the plurality of output files includes one or more scalable vector graphic files.

13. The system of claim 7 , wherein the plurality of output files includes one or more scalable vector graphic files.
