FlattEx generates code to be inserted into the scenery.cfg file.
Another option for excludes is
Excbuilder V2. It generates a .bgl file so no editing of the scenery.cfg file.
*You'll no doubt need to 'flatten' so that Afcad runways, etc., will show properly.
*You may also want to change the terrain texture around the airport.
**As I use SBuilder, that does all the above and more, I can't suggest single utilities for the last 2. You could browse Scenery.org, or maybe someone can make suggestions.

At that time [1909] the chief engineer was almost always the chief test pilot as well. That had the fortunate result of eliminating poor engineering early in aviation.
