Looks ok so far, thank you …
The problem here is really the database behind FSHud. I have no idea how this works, if FSHud uses the sceneries in MSFS, and when and in what way.
The data looks good so far, and so does your configuration. So, it must be any combination in some areas. It is doubtful that this has something to do with the MSFS AIRAC because it would happen everywhere, not only in specific areas.
I remember that FSHud had fixed something with scenery incompatibility for a few months, but please don’t ask me what, and if this is correct.
We have no background information about this tool because FSHud offers its own data generated from our data. It’s like a black box for us, sorry.
Cheers
