• Which the release of FS2020 we see an explosition of activity on the forun and of course we are very happy to see this. But having all questions about FS2020 in one forum becomes a bit messy. So therefore we would like to ask you all to use the following guidelines when posting your questions:

    • Tag FS2020 specific questions with the MSFS2020 tag.
    • Questions about making 3D assets can be posted in the 3D asset design forum. Either post them in the subforum of the modelling tool you use or in the general forum if they are general.
    • Questions about aircraft design can be posted in the Aircraft design forum
    • Questions about airport design can be posted in the FS2020 airport design forum. Once airport development tools have been updated for FS2020 you can post tool speciifc questions in the subforums of those tools as well of course.
    • Questions about terrain design can be posted in the FS2020 terrain design forum.
    • Questions about SimConnect can be posted in the SimConnect forum.

    Any other question that is not specific to an aspect of development or tool can be posted in the General chat forum.

    By following these guidelines we make sure that the forums remain easy to read for everybody and also that the right people can find your post to answer it.

Airport BGL File Format MSFS 2024?

Hi,
I've noticed that addon airports .BGL files that are particularly created for MSFS 2024, such as the latest INIBUILDS EGCC, do not comply to the file format for MSFS2020, as described here: BGL_File_Format
When parsing the .BGL I can detect that there is an Airport in the file but not any deeper, the code 0x0056 is not used. Hence I cannot find the stands with their lat/lon positions which is needed by my freeware PSXT utility.

Is there any knowledge about the coding differences, or can somebody point me to documentation?

Any help will be much appreciated,

Nico Kaan
 
There has been no work done with the bgl file format for airports in 2024. Perhaps Arno has looked into this, but I doubt it. Most devs are using 2020 decompilations, and using those as a base to make 2024 alterations. Also, in the SDK tools folder, there is BglExplorer.exe that gives some info about 2024 bgls.
 
An additional potential source of insight on how to access more of MSFS 2024 file info might be the Little NavMap project: :idea:

Little Navmap 3.0.14 released​

Notes​

This is a stable version of Little Navmap which adds support for MSFS 2024"


Note as well, the approach this developer has implemented for MSFS 2024 ...and 'why':

"MSFS 2024 Scenery Library #1198

There are limitations since Little Navmap has to load the scenery library through the MSFS 2024 SimConnect interface and cannot rely on files anymore. All files used by Little Navmap from MSFS 2020 were dropped due to the streaming only approach of MSFS 2024. This required a full new data compiler implementation.

Please read Frequently asked Questions - MSFS 2024 Scenery Library Limitations for a detailed list of limitations."

FYI: Important caveats regarding limitations in the current methods Little NavMap uses are here:

"FAQ:

A MSFS 2020 add-on does not show up after reloading the scenery library in Little Navmap​


Encrypted add-on airports in MSFS cannot be read by Little Navmap.


The add-on is locked down with a DRM (Digital Restriction Management) scheme if you find a file BGL.fsarchive in the add-on folders. Little Navmap will not show a new airport or only the stock airport if an add-on replaces a stock one.


You can still use the stock airport shown in Little Navmap for flight planning but keep in mind that parking, taxiways or aprons might probably look different in the simulator.


Buy add-ons directly from developers instead of the Microsoft market which enforces encryption. Alternatively you can also use and support freeware scenery."

Thx for your help. I have contacted Alex and he also pointed me to the SimConnect method. I'll be looking into that solution today to see if that can give PSXT the parking positions of an airport.

Nope, I have not looked into airports. I have only looked into reading the scenery object from the modellib.bgl file and reading object placement information from the BGL files containing that.
