I may be recalling the wrong modification. Well, this matches with my memories about the respective patch - as far as I can tell there was just this single approach at contributing a rewrite of the tire/ground reaction feature to JSBSim. If I summarize correctly then we a) still don't have a single FDM in FlightGear that does proper simulation of this feature and b) it looks like major changes are required to get it going. To put it a bit provoking (no personal offense intended!) for the sake of getting the status right, this looks to me that we're never going to have this feature of proper tire/ground reaction simulation in FlightGear simply because the involved folks prefer to play around with smaller, 'approximative' workarounds forever instead of biting the bullet just once. Right ?
