the latest upgrade of GSX and I was disappointed in the modifications on the above two items. Seems the fuel trucks no longer spawn from nearby vehicle parking but from somewhere way distant from the airport. It takes forever to load large aircraft for realistic turn-around time.
This change has been made many months ago and, like in all changes, it's always for a good reason. The previous version had a minimum and maximum search range to find a suitable place for the truck to spawn from. The minimum range was to prevent having the truck spawning in front of you, and the maximum range was to prevent excessive waiting.
If the airport AFCAD is well made, it shouldn't be a problem finding a suitable fuel or vehicle parking within these ranges, since in real life there are multiple vehicles parking spot, if the airport is large enough.
But following users reports (which we always do), we found out that many 3rd party AFCADs are either missing entirely such parking spots, or they have too few or even just one. So, in order to allow GSX to always find a suitable parking spot, we removed the maximum range, so we search in the whole airport, so we don't miss any fuel/vehicle parking, even if it's far away.
It's likely the airport you are using has been made this way: with a lone fuel/vehicle parking and you were parked far away from it. In previous versions, the truck might not have appeared at all so, this is clearly an improvement.
Also it seems very unrealistic that 420 passengers can board or unboard in less than a minute! Umberto, why the changes?
I'm not sure what you are referring to now. The timing per passenger has always been user settable in GSX, since the first version. Nothing has changed here.
However, what might not add up, is the estimated number of passengers calculated by GSX which is the actual station load of the airplane divided by 220 lbs (average weight of a passenger + luggage ). The calculation is made when you select either Boarding or Deboarding. This means, in order to allow GSX to calculate a reasonable number of passengers, you must load the airplane first, then call GSX.
Now, it's likely that, with an airplane that simulate a progressive load of the stations, the "final" weight won't be reached for a while so, if you call GSX when the process has just started, the estimated number of passengers will be much lower. This means, with these airplanes, either you wait until they completed THEIR own progressive loading simulation and then call GSX, or use whatever function they have (if available), to load "instantly", so you won't have to wait to call GSX.
Also the refueling is not fueling up to the correct amount. I requested 230,000 lbs for the PMDG B744 and when GSX said it was completed I had about 20,000 pounds less.
There's big misunderstanding here and, it's due because you haven't read the manual which explains with some example how the new refueling system works.
On an airplane that is configured to have its custom fuel simulation, and the PMDG 744 certainly is ( at least, this is how we configured it in the GSX default database ),
GSX is not refueling the airplane. With these airplanes, the only thing that GSX does, is to continue sending fuel trucks and play its own animations, for as long the AIRPLANE is continuing to increase the fuel quantity with its own progressive fuel simulation. At NO point GSX will EVER touch the fuel quantity on such planes.
The ONLY case where GSX really changes the fuel quantities, is with default airplanes, or any other airplane that has the "Show the FSX Fuel and Cargo page" option enabled in the airplane configuration page.
I suggest reading the GSX manual starting from Page 15, there are several example and it's explained how the program behave differently, depending if the airplane uses a default fuel system or a custom one and, if it uses a custom one, it even changes depending if it has a progressive refueling simulation or not.
