How do I Change the Airport Name or Altitude? (1.65)
This feature replaces the existing Change Airport Altitude function. It is not possible to change the name or altitude of an airport via the normal addon scenery bgl file. Unlike all the other changes you might make the airport identification and altitude properties are read from the first file loaded rather than the last. So to get a change to be remembered we need to create a small Bgl file (often called a stub or pre-load file) that contains this information and is stored in ..\Scenery\World\scenery. This ensures that the pre-load file is read before any other files including the stock files.
