Not hard at all. The only reason it doesn't is that, heh, I got really confused about how to figure out the units and precedence rules. Speed can be set in about a zillion ways (roll/pitch/heading vs. x/y/z vs. north/east/down coordinates, IAS, TAS, knots, m/s, mach, etc...), and it seemed like the FDM is responsible for figuring out what goes where. If you can point me at a property to read for an authoritative velocity source, I'm there. :) A slightly harder problem is getting the aircraft trimmed for the selected environment. A really annoying property of most (all?) sims is that they start you out at the right point, but way out of trim and you wreck the setup trying to get stabilized. I can probably canibalize some of the solver code for that. Andy -- Andrew J.
