Got me. I can't see anything there. I have to say that I'm a bit confused about the VRP values that are in CVS now. It would be helpful if the config files had both a reminder as to what the axes were (e.g. what is x,y,z) and a verbal description of what the VRP values represent. In any case, the VRP values in the config do not affect the output of the FDM, right? As far as this problem is concerned, it has been around a lot longer than the VRP mod. One thing I noticed is the altitude-agl is reported at the gear level by YASim, where JSBSim reports the distance of the nose above the ground. I'm not sure one is better than the other, but perhaps this should be standardized.
