OK, in working to fix the gear jitter I've discovered some things about the winds modeled in FlightGear. I used this command line: fgfs [EMAIL PROTECTED] --aircraft=c172r --turbulence=0.0 This set up the winds as I wanted. However, even though "turbulence" was set to zero, there was still lots of noise present in the wind velocity coming from FlightGear. The wind seemed to vary +/- 5 to 10 ft/sec. Also, the variance rate of chance was on the order of tens of milliseconds. I was logging data at 20Hz, and at one time step the wind velocity would be at 10 ft/sec, the next it would be at 20, and the next it would be back at 10. Obviously, that's physically impossible. Can someone shed some light on FlightGear's modeling of winds and turbulence? BTW, I'm using current code out of FlightGear CVS.
