Pushback DirectionGSX reads the Pushback preference from the AFCAD file, which can be Left, Right, Both or None. Normally GSX will not allow pushback from a parking position that has its preference set to None, on the assumption the scenery designer had a specific reason to disallow Pushback on that parking spot. But, in case the AFCAD is simply not accurate, this option will allow you to instruct GSX to override the Push- back preference set in the AFCAD with the one specified here.
