Fabrice Erdinger of France has released a small freeware utility called Lucifer. The devilish name has to do with the purpose of the utility; to allow technical problems to be simulated in your FS aircraft (FS2004 and FSX). Fabrice hosts the software on his CyberAvia web site where you can download it for free. If you like it, send him a postcard ! You’ll need to read some French in order to download and install it.
