I see on the forum some problems about the CG when fuel + pax + cargo are loaded via Gsx.
I have no problem with that.
Maybe the problem is the following. Sorry if it's not.
1-With the fuel planner I adjust the CoG with the slider until the TOW %MAC is GREEN. I bring this precision because on all the pictures of the fuel planner accompanying the posts related to this problem, I notice that the Adjust CoG slider is always in "Reset" position, therefore the TOW %MAC is not GREEN.
2-I click on Generate Loadsheet.
3-Once in the plane I Init the Loadsheet, then via GSX I load the fuel, pax and so ...
The trim in the Load and Fuel aircraft matches the one found in the Fuel Planner. Everything is ok for me.
