Custom payload EFB API for livery developers and VAs

[jbud]

Aircraft Version

Experimental

Description

Would love to see a weights and balance API for the EFB payload section so that livery designers for the A32NX could include 2-class or 4-class seating maps by loading a json file with seat dimensions layout, empty weight, and default balance for the configuration.

References (optional)

Example of the A320-200 DAL layout
seatmap

A reference option for the json layout could be similar to how headwind has their seat map done: here
However an api would need to be developed to load the json from the selected livery similar to how liveries can alter the registration tag in the cockpit.

Additional info (optional)

This was partially requested in issue #7362 but I wanted to have a more firm idea on the request.

Here's an example of a json file to make the API use easier. I know it would be an undertaking to procedurally generate the seat coordinates based on rows and columns but hopefully not too hard.

I started working on this and I have made some progress. I do have a lot to do but for now here's what it looks like. if ANYONE wants to take over I'm sure it can be done quicker than myself. The way I've done it so far is hacky and requires either an external tool, or a full rebuild of the plane each time you switch layouts. I do commit to having it fully flightworthy before any PR is opened. anyway here's a preview

Currently looking into using SimBrief airframe to change the seat map. this may be an optimal way for the time being as importing dynamically seems to be giving me trouble.

May be affected by #7442 which allows external input into the boarding system
