In P3Dv4.4, I called the GSX fuel truck, selected 50%, it removed my cargo, left the passengers, but the payload reverted to 0.0lbs, and the fuel remained at 100%. I had to remove all the passengers, re-add them and the cargo, then I selected 37.8 for the fuel to make it 50%. In P3Dv3.4 it did the same thing. I haven't got time at the moment to try FSX-SE, but will try it later when I do have time. Because of this, I won't be using the GSX refueling with the 757 III in P3D!

Fully agree with you Mark as I was doing a test flight from GCXO(Tenerife North) and did the CDU FMC bit first, and upon calling for the GSX fuel truck, voila! the Payload reverted to zero.

Something's screwed with GSX. Like you, will give it a miss calling for the Fuel Truck.
