Suggestions are welcome.
FWIW, there is a pretty thorough description of the reference frames used by the JSBSim FDM in the reference manual (www.jsbsim.org/JSBSimReferenceManual.pdf) on pages 84-91. That includes a description of the EOM, as well. Of course, there is no mention of frames concerned with view angles and sun positioning. jb ------------------------------------------------------------------------------ Let Crystal Reports handle the reporting - Free Crystal Reports 2008 30-Day trial.
