How do I Create a New Non-Stock Airport? (1.65)
This is an updated version of the existing New Airport Wizard that allows you to set the coordinates and altitude of a new non-stock airport from the user aircraft position in the simulator
Connecting to the simulator
If you want to use the new feature of getting the location of your airport from the simulator you need to be connected to it before you start. Open the sim and place your user aircraft at the location you want for the reference point of your new airport.
Open the new airport dialog
New Airport Properties
If the Get From Sim button is not active then ADE is not connected to the sim. If you want to connect then Cancel this dialog, connect to the sim and open the dialog again. Of course if you want to enter the coordinates and altitude yourself you do not need to connect and you can just enter the data yourself.
