Well, FlighGear has its own atmosphere model that is also used by the other subsystems (e.g. instruments, weather reports, visual system, AI traffic and whatnot). So far there has been few reasons not use that model also for the FDM. I think the FDM only needs to know the atmospheric

The way I understand this, the issues are to some degree separate (?). I believe (correct me if I'm wrong) that what Jon is largely talking about is the altitude extrapolation of atmosphere conditions, i.e. given that I specify pressure, temperature and dew point at sea level, how will these

I'm working on modifying the interface between JSBSim and FlightGear to work with the new JSBSim standard atmosphere model. There are two or three ways that the atmosphere model can be modified by the calling application: A temperature bias can be added to the entire temperature profile (from sea

Torsten, Eventually, there will be a null atmosphere model that will allow flightgear to completely control the temperature pressure and density. There will also be several other atmosphere models available in future versions of JSBSim. I'd strongly recommend using the JSBSim atmosphere when
