I have the following question. In most flights, after loading the SimBrief loadsheet, with ZFW ranging anywhere between 164 to 171 tons, I always see the ZFW CG value of 25,9% in the Loadsheet page of OIS. Is this what is supposed to happen? I would expect at least some spread. Alternatively - can I find the the calculated ZFW CG somewhere else?

Thanks, Jan

The CG on the Loadsheet page isn't really a "load sheet" value. It's the current live CG of the aircraft. You can watch it change during progressive loading. 

This makes it not very useful - you can't input it into the FMS until the aircraft is fully loaded. It's always 25.9% when the plane is empty, and you're looking at it after importing the Simbrief load but before you've actually loaded that into the aircraft (using the buttons on the load sheet page, or progressively with GSX).

I submitted a suggestion on Discord to have a field where it previews the "Estimated Load" CG, which is what an actual load sheet would show you. They said they'd look into it.
