We already have a solution, which is asking the scenery developer for an unencrypted version of the airport .BGL to be placed in the GSX airport profiles folder.
The better long-term solution will be using the new Facilities API, which is currently available ONLY in the SU10 Beta, which will allow to get data about the airport from the sim, without having to open the airport .BGL files, and should even eliminate the requirement of having an airport cache, making the program far easier to use and less likely to be affected by issue like corrupted .BGLs, filesizes, etc.
As explained in many other threads, we are already working with the Beta API and we are already working on integrating it with GSX, and as of *today* the new API is still missing some features we require and already asked to Asobo as soon the Beta came out, that is Runway Starts and Jetways/Jetway Links. Asobo has confirmed Runway Starts will come, but as of today, hasn't confirmed if data about Jetways/Jetways links will, which of course is important for GSX.
As of today, there's no confirmed release date for SU10, which might be a good sign, since if they are taking their time to fix all remaining issues, it *possible* they'll have time to add the missing information about Jetways we need ( and maybe fix bugs in the jetway animation system ) but of course it's noting we have any control over it.
Obviously, we can't release anything until SU10 comes out officially, since it we changed the software now, it will work ONLY with the SU10 Beta.
