There are probably a couple of approaches at least. I've been looking hard at this over the past two years, and especially over the past month or two. I've reached a point where the gear jitter for a parked aircraft has been *massively* reduced in tests, and I am very pleased. I have yet to try this while integrated with FlightGear. I may post some plots showing the reduction. I'm considering writing this approach up as an AIAA paper for the modeling and simulation technical conference next August. In any case, I'll be describing the approach later, perhaps in the next JSBSim newsletter. Jon ------------------------------------------------------------------------- Take Surveys. Earn Cash.
