In the actual doc, this is what you say about vehicles spawning point:
"All GSX vehicles that comes from away, by default are spawned from other Parking spots of the “Vehicle” kind, with the Fuel Truck starting from the “Fuel” Parking types instead."
This is valid and work quite well for airport which are GSX compatible and have these "vehicle spots" you mention, but what about addon which are not compatible like, for example, "devinci Dakar GOBD airport" I just bought yesterday ? Actually, not a word in the doc about that case. From my tests, GSX Pro seem, most of the time, to set the spawn point RIGHT ON THE PARKING POSITION WHERE IS PLACED MY AIRCRAFT !!! In other words, it is right under your aircaft, with horrible effects on the path of these vehicles, starting doing wonky moves on wonky paths. Something which is REALLY A BAD THINGS ! This is almost the behavior I have with my new Dakar GOBD addon, but I guess this should happen also with other "incompatible" addons.
I study carefully all informations I was able to found about "GSX spawing point" everywhere, in all your forums and even globally on internet. I found in an old thread (
https://www.fsdreamteam.com/forum/index.php?topic=20493.0), that you answered that with such compatibility problem: "... a random parking will be used instead so, you can use the free ADE utility to add these points" and you answered also: "No need to duplicate in GSX something that is already possible to do with a very good freeware utility". This was maybe valid in 2019, with GSX for old FSX version, but for sure, this is not anymore possible !
Nevertheless, to be sure of that I tried to follow this ADE utility track and installed the "ADE 2020 alpha 20". But this is obviously something much more complicate now, than with the good old ADE I used my self a lot in the time of FS9 & FS10 !!! I give up immediately, when I discover that this ADE version require the MSFS 2020 SDK to be fully installed ! No, sorry, Umberto, but I am not putting my fingers in such a complex heavy and indigest solution, when GSX Pro can DO THINGS MUCH MORE CLEVERLY and even maybe, ADD A NEW FEATURE in the airport editor to allow the user to offet the GSX determined spawn point, whatever kind it is !
Personnaly, I would in this case, maybe choose a parking position, but almost one WHO IS FAR ENOUGH FROM MY AIRCRAFT. I guess that it should't be complicate to calculate which is the best parking position to choose. Moreover, whatever was used to choose the spawn point, if we can display it in airport editor and move it with usual editor commands, this would be perfect.
Hope you will approve this obvious improvement proposition.
