There is a ditch at the end of Bidford Gliding Centre furthest from the main road. I have flown in and out of there in real life in both gliders and powered. In MSFS, the addon for Bidford has this ditch and every time you fly over it you get bumped up and down. Didn't have that happen once in real life.
I don't think the atmospheric interaction with the aircraft is overdone. I do, however, think that there is too much in the way of extreme updrafts from minor geographical features and that these go to a considerable height. Perhaps that is a part of the problem?
