I've recently been flying in a light plane for the first time - the biggest difference bewteen real life and FlightGear is the turbulence.If FlightGear is to be as good a simulation as MSFS, it must model the general buffeting that you experience, even on a calm day.I guess this could be done through a random and sudden increase and decrease in airspeed (which is essentially what happens) plus a related random increase and decrease in roll, yaw etc - it gets too technical for me at this point.But having flown a real plane, I feel that the FlightGear experience is far from realistic, simply because the air is simulated as being a smooth medium.(Full marks in everything else though - I lurrve the 3D cockpits and intuitive look-around control)

I beleve the turbulence can be edited by searching around the advanced menu right before you run the simulator.

Turbulence was working (for some aircraft anyway) in FlightGear version 0.9.9. It was broken in 0.9.10. I believe it's been fixed in CVS FlightGear.
