I understand the scoring system, but GSX contains things that do not exist in real life as the stairs and baggage loaders of GOL. It could be much easier to define a handler for a certain plane, or leave this option to the user to choose whether to use or not.
As I've said, GSX doesn't relate the handler to the user airplane, both because it's just wrong, since the ground handler is something related to the SCENERY, and because many airplane don't use the atc_airline_code in the first place.
So, if you must edit something anyway, like your airplane.cfg, it's best having to edit what is suppsed to be edited, which is the scenery.
Many scenarios that have freeware for Brazilian airports do not have the correct parking codes
That's not a GSX issue then, it's a scenery issue, than can be easily edited using any of the available AFCAD editors out there, such ADE.
So we have to upgrade ALL GSX scenarios that only works in a same way?
It doesn't take much effort to edit airline codes for a scenery, also because it's possible using ADE or AFX to change several of them at the same time.
I see no problem in letting the user who paid for the product using the handlers the way he wants.
We'll have an update that will allow to select the ground operator, but from all candidates that are available to the parking.
The handler of TAM is found in all national airports, but how did new companies with couatl.icaoprefixes, it virtually disappears.
This sentence is not clear. Explain what you would like to do.
After all, it is only offered to the airline TAM and no other. It is also unrealistic to see stairs TAM another plane that is not theirs, so why can not set correctly?
It can be set more correctly, if you HAVE the correct information for a ground handler on that airport.
Add it with the Painkit, and give it more priority by assigning to it a 4 score in the ICAO and, eventually, reduce the score for TAM in that airport (only if it was already at 4), so TAM will not appear anymore there, and your selected ground operator will appear instead of TAM
