Thanks. I’ve noticed that just about any ‘wrinkle’ in the terrain is enough to cause this turbulence effect.
For example, the screenshot below is from my flight earlier today, where I was about to capture the glideslope for ILS Rwy 10 at RCSS. Those hills in the foreground were enough to make my plane rock from side-to-side, before the effect eventually dissipated once I crossed into the city. The approach chart certainly makes no mention of turbulence in this area…
