Hi fellow wiki editors!

To help newly registered users get more familiar with the wiki (and maybe older users too) there is now a {{Welcome to the wiki}} template. Have a look at it and feel free to add it to new users discussion pages (and perhaps your own).

I have tried to keep the template short, but meaningful. /Johan G

$FG_HOME is a placeholder variable representing the path to where user-specific FlightGear data is stored (not application data). Unlike $FG_ROOT, $FG_HOME is NOT an environment variable that needs to be specifically configured for FlightGear to work.

$FG_HOME is only used to refer to the OS-specific location for some settings/folders. The actual location of $FG_HOME will be determined by the fgfs binary during startup, it is a name for a directory that varies with the various operating systems supported by FG (Windows, OSX and Linux) and it stores information between sessions, such as: configuration/preferences, properties marked with the "user-archive" attribute and aircraft-specific settings (using the data helper class in aircraft.nas). $FG_HOME is also the location for the SQLite-based NavDB cache.

Common paths

  • Linux: ~/.fgfs/
  • Mac OS X: ~/Library/Application Support/FlightGear (to learn more about viewing hidden folders, see [1])
As all future FlightGear versions will take their preferences from here, it is a good idea to have their access available easily.
Desktop/Finder/Go/Go to Folder is where you need to start.
When given the option, input: ~/Library/Application Support/FlightGear
It is probably a good idea to have '~/Library/Application Support/FlightGear' saved on a Stickies note just in case you forget it.
If you want/need to refer to any of these files frequently, you could make an alias of a file, or the whole folder, and place it somewhere easier to access.
  • Windows: %APPDATA%\flightgear.org\
 %APPDATA% is another environment variable that depends on your Windows version. On XP and older, it can be found under C:\Documents and Settings\{username}\Application Data. On Vista and later it can be found under C:\Users\{username}\AppData. The folder is hidden by default; see these instructions to unhide the folder.

You can determine the location of your $FG_HOME by using the property tree browser and checking the value of /sim/fg-home, the /sim/ branch is also the place where you can find other folders, such as fg-root, fg-scenery and the current working directory (fg-current).
