2 Or... follow Umbertos advice and disable the 787
I don't know what you mean with "disable the 787". Is this a typo ?
Since you are saying it was following my advice, than I assume you really meant DISABLE the "Fuel and cargo dialog" during refueling" option which is, incidentally, exactly how the QW 787 is pre-configured by FSDT!
Yes, the option you keep saying you "cannot Disable", which I tried multiple times to tell you surely can.
1 Fuel truck arrives
2 A GSX window will offer a list of fuel amounts that you can choose from
Assuming that following my advice to "disable the 787" ( I think I should know what I advised ) really meant disable the "Fuel and cargo dialog" during refueling" option, if you do that, you are not even supposed to see the GSX window asking how much fuel you want. Instead, you'll see GSX asking to use any other method to load fuel.
I suspect with "disable the 787", you meant something else and it wasn't the "Fuel and cargo dialog". INSTEAD, it was the "Detect custom aircraft system refueling", even if you already listed it as Disable in your 1st point, the one *before* the 2nd where you said "
OR Follow Umberto's advice" so, even if you meant this option, the way you wrote seemed to indicate you already took that as granted, since it was in your 1st point *before* the OR.
Because, the whole procedure in your point #2, seems to indicate a perfectly working GSX refueling.
Please confirm it again: is following your procedure in #2 WORKS FOR YOU ? If yes, that's ends the whole discussion, because that's how GSX is supposed to work when it's allowed to refuel the airplane by itself.
And again, even if you Disable the option to have GSX do the refueling, the procedure would change but, you couldn't possibly end in a situation in which you cannot complete the refueling, surely NOT because of GSX, because GSX is not refueling in that case.
So, assuming you are now saying your procedure #2 works, we can say GSX can work with the 787 in both modes so, there wasn't any issue to begin with, other than having enabled the "Detect custom aircraft system refueling", which should probably not used except in the very specific case I explained above.
One could of course hope for the FSDT team to investigate this 787/GSX-specific error-behavior and find a fix, but if I understand the approach hear so far, the chances are pretty close to zero. They love to talk about how some things are working rather than speak about solutions to what is not working.
First, I would tell you that, if there WAS a bug to fix ( there isn't ), it would have probably taken way less time than the time spent trying to make you understand why and how things works ( they do ) the way they do.
I'm starting to suspect the ONLY real "issue" you had, was JUST the "Detect custom aircraft system refueling", which I agree can be confusing, and it's presented in a too easily accessible way, when in fact should be used only in fringe cases.
Many users turn it on, because they think this way GSX can "recognize" if an airplane HAS a custom fuel system, which is not what it does. What makes GSX knowing if the aircraft HAS a custom fuel system it's the airplane configuration, that is the "Fuel and cargo dialog" during refueling"!
The "Detect custom aircraft system refueling" might have been worded more correctly ( if we had more space on screen ) as:
"Detect when an airplane starts refueling itself and auto-call GSX fuel trucks"
Because this is what it does, and it's ONLY useful with planes ( like the PMDG 777, for example ) that have a simulated "turn-around" procedure, which can take a changing amount of time, which the airplane own progressive refueling is A PART OF, that can start at any time so, with this option Enabled, you are NOT supposed to call GSX fuel trucks manually: they will be sent automatically as soon the plane will start to refuel itself.
So, the only real problem is the option is not clearly explained, it's not useful with airplanes that don't have that kind of automation ( surely it's useless for the 787 ), and will likely have issues if you keep it enabled when the airplane doesn't need it.
I also think we'll probably need to make it aircraft-specific, not a global option, and keep it disabled for everything except maybe the PMDG planes.
And not, the very presence of that option was added ONLY because PMDG ( the only developer of hi-quality planes with this attitude ) didn't want to cooperate with us for some reason, because OUR proposal they rejected would have made the refueling so much better for all users, and it was a way to SYNCHRONIZE the airplane own refueling with GSX so, instead of GSX having to guess what the airplane is doing, it would be the airplane itself calling GSX when it knows is right to do that.
That's how FSLabs integration works, and that's why it works so incredibly well with GSX: because FsLabs worked with us and add code to their airplane to be sure they are working as good as possible.
