This panel is to be used for MD-11s and other trijets aswell, its an easy to use and complex panel. To install it just simple drop the files from the "Panel" file inside the zip onto the panel folder of the aircraft u want to use it on, and drop the content inside the Gauges folder inside the Gauges folder located on your main FS9 directory. Basically thats all there is to it. I hope u enjoy it.
