I dug up Jon's old, disabled turbulence support in JSBSim, added a tiny bit of damping, and hooked it up to FlightGear. All JSBSim aircraft now include preliminary, use-at-your-own-risk turbulence support. To set turbulence, use the
/environment/turbulence-norm property in FlightGear: a value of 0.0 means perfectly smooth air, and a value of 1.0 means severe turbulence. The property is also linked up to a slider in winds dialog box under the Weather/Winds menu entry. Jon gets all the credit for writing this code in the first place, but I'll accept any blame for rolling it out before it was ready for prime time. I'll need to damp the ASI needle a bit, since turbulence is making it jump around too much right now. Here's a command-line for a fun approach (it would be more fun if I added a strong crosswind and low visibility, but you'll get the point): fgfs --offset-distance=2 --altitude=1000 --vc=80 --prop:/environment/turbulence-norm=1.0 (Keep your airspeed up right to the flare.)
