I was wondering whether this was possible and how to do this?
You can't do it for all airports at once, and it would be wrong if you could because:
- VGDS are diverse types, sometimes even in the same airports, some gates use one type, other gates another one, and others use Marshallers.
- VGDS not only are different, but they are also mounted in different ways, depending on which building they are located. Heavy gates usually have them placed higher as well, to be visible from the higher cabin of large airplanes that will typically use that stand.
So, if you care for realism and usability and don't want spend time customizing things, you should download a pre-made airport profile, which should hopefully have placed the proper VGDS in the right places.
If you don't care for realism, and you just want the VGDS no matter what, you can do as follows:
- Before flying to an airport for the first time, open the GSX Parking Customization page, and click on the left tree the "Airport" node. This will select ALL parking positions at once, meaning any change in the right page will apply to ALL parking spots in the airport.
- Select one of the "Ground" mounted VGDS from the list. Being mounted on ground, it means they won't require to be placed as precisely as they would have been, if they had been mounted on a building.
- Click Apply. Now the whole airport has VGDS.
