When running FlightGear from a [[command line]], you can set $FG_ROOT via <tt>--fg-root=path/to/root</tt>. In [[FGRun]], it is set on the paths page, previous to the aircraft selection page.
The environment variable <code>'''$FG_ROOT'''</code> is referring to the path of the main data directory of [[FlightGear]], which contains the so called ''base package''. The base package consists of the default [[aircraft]] and [[scenery]], [[Menubar|GUI]] files, sounds, 3D models etc.
