i did not speak with the AFCAD File..so i dont know what he say.
Unfortunately, regardless if you are interested or not knowing what the AFCAD has to say, its word is law, when GSX is concerned.
Of course, GSX being the flexible program that it is, has a nice "parking customization" option, which a fairly explicative dialog box, that will list what GSX has heard from the AFCAD file (they both speak the same language), and has offered to translate it to you, in a readable way.
So, if GSX is listing "None" as a Pushback preference, which has been read from the AFCAD file, in common language means:
"I, the scenery designer, regardless of the the time it took to draw the yellow lines, have decided that Pushback here should be set to None".In reality, this is not really the case, and the most common case is, instead:
"I, the scenery designer, have forgot to set a proper Pushback preference, because I used the popular free ADE program that, for many past versions didn't have any means to set it, and always set it to None, but since FSX doesn't respect that flag correctly, I don't care much".But again, GSX being the flexible program that it is, in the nice "parking customization" dialog, allows you to CHANGE what the scenery designer has forgot to set in the AFCAD, which is why,
as explained in the GSX manual in the chapter that discuss the scenery customization options, you can set a different Pushback preference, overriding what the original scenery designer did in his scenery.
And yes, you can set it for a single parking, but even for multiple parkings at once, even for the whole airport at once, because it's usually assumed that, if a designer works that way, he probably forgot to set ANY Pushback preference for the whole airport, so we can safely assume that that particular parking wasn't set to "None" for some real-world reason.
Because this is why GSX RESPECT the Pushback preference set as "None": to allow scenery designers that really MEANT to block pushback on a certain parking, because of real-life constraint, to be able to make a difference between parkings where either Left/Right is allowed ( the "Both" preference ) and parkings where Pushback is FORBIDDEN, which is the "None" preference.
But of course, since GSX cannot possibly know if the designer really mean it, or it was just an oversight, it doesn't have any other option than to trust the AFCAD and let you OVERRIDE IT.
The "Straight Pushback" option has been requested by many users, and we finally added it, both because sometimes it's useful as an additional option on a parking where Left/Right is working, but also because at least SOME Pushback would work, even at those airports the designer set (intentionally or by mistake) the preference to "None", so users that don't read the manual, and don't know that why GSX works this way and they also can change it, won't be mislead into thinking that Pushback is not working at all at some place, because of some "GSX bug"...
But i can see the yellow lines in the scenerie.
Well, the scenery designer can draw whatever he wants on ground, but what makes the sim working, is the AFCAD.
