[http://jsbsim.sourceforge.net/aeromatic2.html Aeromatic] can be used to create aircraft configuration files for use with the JSBSim Flight Dynamics Model. The configuration file format produced using this utility is version 2.0, and is incompatable with older formats because of an extensive overhaul of JSBSim's XML code that occured in December of 2004. Aeromatic is a online web tool, written in PHP, not a standalone program. | [http://jsbsim.sourceforge.net/aeromatic2.html Aeromatic] can be used to create aircraft configuration files for use with the JSBSim Flight Dynamics Model.

You will need at least | You will need at least three files for a complete configuration, an '''aircraft file''' containing information on the aircraft's mass properties, propulsion, flight control, aerodynamic properties, etc., an '''engine file''' describing the engine(s), and a '''thruster file.''' Thrusters can be rotors, propellers or direct. All turbine and rocket engines use the default "direct" thruster. Piston, electric and turboprops need rotors or propellers. Aeromatic will generate plausible configuration files for your aircraft using some simplifying assumptions. Note that Aeromatic allows only one type of engine to be defined per aircraft. If you want to mix engine types you'll have to make the necessary changes by hand. | ||
Be careful when tweaking the resulting configuration file, because it's easy to make changes that will result in an unflyable FDM. Common errors are: moving things around so they are not left/right symmetrical, and moving the CG too far. | Be careful when tweaking the resulting configuration file, because it's easy to make changes that will result in an unflyable FDM.
