I like the GSX SOdE jetways better due to better customization options and ability to edit positioning to better match the aircraft parking there.
That being said, I did finish doing a full update using GSX L2 for IS KATL 2016 high density last night. It’s in no way perfect, but I’d be happy to share it with the community, with your permission, because it is updated from your original ini file that contains your work on the pushback. I would need to make a few small adjustments before I upload it tho. I set the jetways for a specific aircraft that would park in the spots based on wingspan (12m-14m = CRJ900, 14m-21m = 737-800, etc) (those numbers are a guess because I don’t have my data in front of me right now, but the finished product is correct), anyway, I used a A380 for gates of 50m but the jetway I wanted wouldn’t match a door on some of the gates so I had to select a different gate. I could easily switch them and test on the 747-400 and upload that file (it likely won’t work with the Project Airbus A380 even with correctly mapped doors and cargos (I can get it to work about half the time). Furthermore, I would need to see about uploading the corrected ADE file associated with the airport because the original had a few duplicate gates (2 A3, 2 A11) and some gates big enough for a 737 size aircraft were assigned to DALX only which could prevent a 737 from parking there despite it being able to fit. Since I made those changes on my copy of the ADE file, GSX will not read the corrected gates properly without the corrected bgl being used. I’m not sure if I can share that file because it is part of the paid download and therefore should be under copyright. I could always just give instructions to make the proper changes.
So if you will give me your permission, I’ll make the jetway changes when I get home from work in about 4 hours and then upload the fully completed ini to the community. (Sorry for the long message)
