All of the airports push back fine with the right direction except one. Gatwick does not push back other than straight. I ask it to push back left or right and it just pushes back half way straight after going off centre line a bit then re correcting then admits it's finished and go put parking break on
It seems there's an error in the airport AFACD file because, if the pushback starts, it means you have set a Left/Right preference, but if it stops halfway in the procedure, it might be a problem with the AFCAD nodes. Not possible to say without checking the scenery. Does it happen on a specific gate ? If yes, which one ?
Also, check that GSX is using the AFCAD that comes with the scenery. If you open the parking customization screen, it will tell you the name of the AFCAD in use by GSX.
