I use P3Dv3 with the latest version of GSX. I have setup P3Dv3 and the PMDG 777 to use KGS. When i use GSX to carry out refueling it indicating lbs / Gallons is there a way to get GSX refueling to indicated KGS.
By me having the PMDG and PFPX set to KGS I'm not sure when GSX refuels in pounds /gallons it putting in the right amout of fuel.
