It can also be used +standalone. + +JSBSim uses config files to represent aircraft and engines. Also, the flight +control system is described in the config file. Normally, for use with +FlightGear, the config files are named this way: +/Aircraft//.cfg . Engines are named +like this: /Engines/.dat . + +Aircraft and engine config files are present in the FGFS-Base package which +must be downloaded from the FlightGear web site at www.flightgear.org or one +of the mirror sites listed there. + +How to run FGFS using JSBSim + +All the various FDMs are currently compiled into FGFS. You can specify which +FDM you want at run time. You can also specify which aircraft you want. +Currently, for JSBSim only the X-15 is available, and possibly the C-172. +Here is an example command line used to start up FlightGear using JSBSim as +the FDM: + +fgfs --fdm=jsb --aircraft=X15 --units-feet --altitude=60000 --uBody=2000 --w +Body=120 + +[Note: uBody is the forward velocity of the aircraft, wBody is the downward +velocity - from the aircraft point of view. This essentially means that the +aircraft is going forward fast and has an angle of attack of about 4 degrees +or so] + + The above command line sets up the initial velocity and altitude to allow +the X15 to glide down. Note that if you fire up the engine, it will burn for +only about two minutes and then run out of fuel - but you will go very, very +fast! + +Check out the JSBSim home page at www.hal-pc.org/~jsb/flightsim.html. Please +report any bugs to jsb@hal-pc.org, or apeden@earthlink.net, or post them to +the fgfs-devel mailing list. + +JSBSim is written by Jon S. Berndt and Tony Peden with contributions by +other FlightGear programmers, as well.
