Steve: It's good you are doing this, and I also enjoyed seeing SVG displayed in my browser in an HTML page. I'm working on something like that, but will not comment until later. I'd like to see the aircraft silhouettes more defined and recognizable as an aircraft type. It looked "wrong" to me initially, until I looked again. Also, you might say that there are two JSBSim coordinate systems - only one is really important for modelers. The JSBSim strucutral frame is the one aircraft modelers will be most interested in. That's the frame that all "located" objects in the JSBSim aircraft config file are placed relative to. It is essentially the most often found "industry convention" coordinate frame. IT is also oriented the same as the FlightGear model frame. The other relevant JSBSim frame is the body frame, which is the frame in which the aircraft forces and accelerations are related to. That frame is the structural frame, rotated 180 degrees about the Y axis, so that the X axis points forward, and Z points down.
