Indeed, i use the aircraft refueling system.
The stange thing is: when i load the loadsheet in the FMC, the FUEL tab lights up amber-oranje,
and when i press the LSK3R the FUEL light becomes green and starts refueling the AC like it should,
and all this without calling for refuelling by the GSX menu.
When using the GSX menu for refuelling, it won't work!!
Any idea if this experimental update is already there or not??
Thanks
