David: Check the JSBSIm API docs on the JSBSim web site (jsbsim.sf.net). Click on the DOCS link, then the API docs link. Select FGAtmosphere. Look for the "UseExternal()" function call. Look for the SetEx***() functions. These will need to be called from FGJSBSim, I believe. Obviously, we'll need to know if/when the external model should be used. Perhaps it should be used whenever we are integrated with FlightGear? > We might also need a relative-humidity property. What units should we > use? Do the FDMs care about humidity? Water vapor has a different density than air. Cold, dry days are the best days to fly, I am told. Warm, moist days would be bad ... then ... I guess. [?] So, what you would need to do is calculate the air density based on water vapor content, temperature, pressure. This will likely involve partial pressure calculations. I've been doing this for an ECLSS sim I've been working on here, lately. Are you up on the perfect gas law? ;-) Jon _______________________________________________ Flightgear-devel mailing list [EMAIL PROTECTED] http://mail.flightgear.org/mailman/listinfo/flightgear-devel
