Thanks for your reply :-).

I have to remove a lot of fuel pumps and valves definitions as the new fuel system (fix) in SU9 does not really like those unconnected pumps and valves which worked great before the patch. For now I have to rename the wasm file to something else in order to get the sim with mod not CTD.

Sadly I can't get use of that great COMM part of the wasm file anymore. My next steps are to figure out why the APU won't remain in Running state after startup and why Battery won't turn on Captain seat displays. Then I will try to implement the COMM html gauge based on B747.

If you want you can have a look into it. I'm not sure what I'm missing for APU

Btw. if you want you can find the project on GitHub.

Looking forward. if you have any ideas
