M. A. REALTURB - REALTURB NORTH AMERICA P3DV4/V5
If you're looking for ways to increase the realism in P3D then RealTurb is one way to do it. It really does make winds and turbulance feel much more realistic. The way turbulence works in P3D by default is unrealistic. In fact, I'm some of my PMDG aircraft manuals, it recommends to disable turbulance effects because it is unrealistic and they said "could cause unexpected behavior" of the aircraft.
