Hi, There are several ways to do this without any code changes to FlightGear. I know FlightGear directly supports data logging to a file but I have not used that option. However, if you are going to use JSBSim you can also use JSBSim's builtin reporting capability. Just add an output section to the JSBSim config file for aircraft you want to use (inside the fdm_config element). This, for example, saves most aircraft state data once per second: <output name="datalog.csv" type="CSV" rate="1"> <rates> ON </rates> <velocities> ON </velocities> <forces> ON </forces> <moments> ON </moments> <position> ON </position> <propulsion> ON </propulsion> <aerosurfaces> ON </aerosurfaces> <fcs> ON </fcs> <ground_reactions> ON </ground_reactions> </output> There are a number of useful articles on the subject in the JSBSim Newsletters available from http://jsbsim.sourceforge.net/ .
