I hope it helps, that's what it's for.

VCockpit entries would be the most logical solution here. The VC is the thing that you see when loading the plane, so all gauges would get initialized without a click or the need to open a popup.

I'd have to test this too and maybe we can advance the Civa mod with this new and easy setup which eliminates at least one big source of errors.

Putting it into the CDU or MSU popup window would be another easy method to get rid of this error source.
I've just placed it in window00 because the CS original panel.cfg had it there.
If you look into my 727 modification, you'll see that I didn't follow the Civa manual and placed it on the AP 2D popup, which is Window03.

Now, with me and you knowing more than before, we can maybe advance those two mods with another place for the initialization gauge of the Civa.
I'll test this soon and then maybe edit my tutorial posts here.
