I believe that it is already necessary to have an editor by means of which oneself can make changes in the airports and airplanes, as objects, houses, landscapes, etc.etc
Not only to play, but putting each one our creative talents.
There is a pretender that at the moment this very well structured that he/she calls it X-Plane, you could take him a look so that they see how many things but they can be made. Thank you.
I agree, especially an editor for navigation aids. There used to be a utility like this for MSFS 98 but I can't remember what the name was.
This editor could open up all the scenery and edit all the aids and airports.
