JSBSim
-JSBSim is an ongoing attempt at producing an OO Flight Dynamics Model (FDM)
-to replace LaRCsim as the default FDM for FlightGear. 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:
-<FG_ROOT>/Aircraft/<aircraft name>/<aircraft name>.cfg . Engines are named
-like this: <FG_ROOT>/Engines/<engine name>.dat .

+this way [case is significant]:
-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:

+using JSBSim as the FDM:
fgfs --fdm=jsb --aircraft=X15 --units-feet --altitude=60000 --uBody=2000 --wBody=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]
+or,
+
+fgfs --fdm=jsb --aircraft=c172
+
+[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!
