We'd better coordinate on this. I've got a mechanism for multiple FDMs already figured out for JSBSim. It doesn't break anything that any other FDM does, either, I believe. What are you doing with the way FDMs are instantiated?! >The bigger problem (or so it seems to me :-)) is the one >Andy brought up. How you model stopping on a moving runway. This really is not a big deal after all, I think. The gear model calculates forces and moments imparted to the aircraft based on the aircraft motion and elevation (and we really should be modeling non-vertical-normal surfaces, too). We simply need to change the elevation in a dynamic way (and the aircraft will respond appropriately) and feed the local frame runway motion to the aircraft so it can calculate the relative motion of the aircraft wrt the runway. The rest will work as is. The aircraft will have a residual airspeed and forces/moments will be generated appropriately.
