I rebuilt an airport, and it seems that there isn’t any ground service! I create some jetways and everything that I was interested to create at the airport. But there isn’t any ground service option! how can I add ground service to this Airport?
I know there is a Tutorials about this, I tried that but it didn’t work!
 Creating An Airport - Improving ILS with Scenery - Microsoft Flight Simulator 20 SDK Tutorials
any idea how to create ground service?
