Okay. I've done the GSX settings for ALL of the 757-200PW Base Pack Models, 757-200RR Expansion Models, 757-300 Expansion Models, and 757 Freighter Expansion Models).
These gsx.cfg's work for FSX, FSX-SE, P3Dv3, and P3Dv4 - which is just as well, as the aircraft model names are the same for all of those flight simulators, and I have the 757 III in all of them.
Now. I have included passenger exits Exit 1, Exit 2, and Exit 3, and in the gsx.cfg's for the passenger aircraft, and the gsx.cfg's are set to
Exit 1 being the preferred exit. If you prefer Exit 2, then change this line in the gsx.cfg for that/those particular aircraft
from this:
preferredexit = 1to this
preferredexit = 2If you don't want a particular exit to be used, go to the
MENU > Add-ons > GSX > Customize aircraft... and when the panel opens, click on the exit you don't want, and another box appears, click on the first at the box that says "Door with custom open/close checks", and select
"No door at this position".
If you remove the PAX 1 entry, you might need to change the
preferredexit = 1 to
preferredexit = 2 in the gsx.cfg (found in %AppData%\Virtuali\Airplanes\<aircraft name here> (i.e. CS_B757-200-III_PW2037)), just in case GSX keeps wanting you to open the PAX 1 entry that you removed. The method for removing the passenger exits, applies to service doors if you don't want to use any/all of them.
With the 757 Freighter models, I have included PAX 1 on the forward port (left side) exit/entry, near the cockpit.
For the 757-200SF, I also included the forward starbort (right side) service door, which you can have removed if you don't want it.
As you can see, there are a lot of options to choose from, so I created the gsx.cfg's to cater for all of them, and changing them to suit yourselves it at your discretion. As long as you don't delete the zip file, or modify any of the .cfg's within the zip file, you can always unzip them again.
