Umberto many thanks for the reply. I checked all the items you highlighted but still cant resolve my issue. I have FSX SP2 and GSX 2 installed. When I first installed GSX2 months ago it worked as expected but at some time in the recent past the issue of no choice of handling agent has arisen.
If I may I will clarify my issue further:
I recently purchased FSDG Djerba and Enfidha. At DTTJ the airport AFCAD has several airlines specified on parking stands. I checked the GSX "handling rules" document and for Tunisia only one handler shows as covering DTxx airports being Tunisair TAR. The entry for TAR shows it covers airports with ICAO DTxx. When I park at DTTJ I get Tunisair equipment which is expected and correct as its the only handler at DTTJ.
Now when I go to Enfidha DTNH the airport AFCAD has no airline codes present on any parking stand - its clean. My expectation is that Tunisair will be the handler and when I park there that s what I get. Except that at DTNH the only handling agent is Havas - the airport is run by TAV - Turkey. I checked the handling rules document for Havas and it only shows ICAO,s for LTxx airports so I added DTNH. Now I expect to have a choice of Tunisair and Havas as the airport is covered by DTxx from Tunisair and DTNH from Havas but I only get Tunisair handling. Only when I go into GSX customise parking and specify Havas in the airline box do I get Havas. This isn't really a problem as being the only handler I simply add Havas to all stands and am good to go.
Now if I go to a US airport e.g. Orbx KJAC some of the AFCAD parking stands have airlines specified and others do not. In the handling rules table I see the major US carriers AA, DL, UA covering Kxxx airports and I added KJAC to all plus some others. When I park at KJAC whether the parking stand AFCAD has an airline code added or not I don't get the choice of handlers I used to get. What I get is a set of steps from UA, another from DL and a hi-loader from AA for example. Only if I specify DL as the handler in the GSX customise parking table do I get all DL equipment.
Question: is the handling rules document I find within the GSX folder texture (the one I am modifying) a live document or an example. If not where is the live document?
As far as I can tell GSX is not reading the handling rules document - only the GSX customise parking airline table.
Any guidance please?
