I tend to haunt bush strips and/or float planes in the way out places.....rarely the opportunity to encounter any kind of wake turbulence. Cubs and Beavers don't really tear up the air much.
And opposed to real world....I have encountered no lee-side vortexes formed by mountains & ridges in FSX.
But I remember being spun over and slammed to the ground following a 747 into an airport driving a light plane of some sort....in FS9. I was running a freeware program of some sort that would generate all sorts of air movement, including wake vortex that could be scaled. Certainly after collecting a whole assortment of approach lights while inverted, I turned down the scalars.....
Anybody remember what the program was? Was there ever an FSX version?
