Hi.
Did an easy one to get aquainted

Have unticked static avro in the configure section in Orbx central.
No pushback on gate 1-4. All vehicles placed as best i could.
Copy the file in to C:\Users\(username)\AppData\Roaming\Virtuali\GSX
Delete or backup any other esks configs you might have in this folder.
Open the file in a editor.
Make sure the path is correct to where you have installed the scenery. I have it set to: afcad_path = G:\Prepar3D v5\ORBX\FTX_GLOBAL\FTX_AA_ESKS\scenery\ESKS_ADEP4_SL_GAStatics.bgl
You might have a different .bgl file if you have other options checked or unchecked in Orbx Central.
Hope you enjoy
