I reicently downloaded Flight Gear, and have been trying to add more planes. I can download and get the files to data/Aircraft, but when I try to use them I get a message that says it can't find the model. What am I doing wrong?

You need to uncompress the downloaded files into a subdirectory below $FG_ROOT/Aircraft, the aircraft files are often in tar.gz/.tgz or .bzip2/.bz2 format, these are widespread compression formats unter linux/unix. More current versions of tools such as WinZip or PowerZIP should be able to work with these files, but if you google for a good freeware compressor you'll also find tools such as IzArc for Win32.When the files have been uncompressed to a subdirectory below $FG_ROOT/Aircraft, fgfs should be able to see them (as long as the permissions (under *nix) are properly set). You can run fgfs --show-aircraft in order to check whether fgfs can 'see' your newly installed aircraft. Alternatively, aircraft should also show up if you are using fgrun, the FlightGear launcher.This seems to be one of the more frequently asked questions, maybe it would be good idea to add something like the above description to the FAQ? (if anybody with CVS access is reading this, please feel free to copy and paste my answer into the FAQ if you consider it sufficient).
