2.6 Why don't my downloaded aircraft show up in my aircraft list?

From FlightSim

Q:

I DON'T KNOW IF ANYONE ELSE IS HAVING A PROBLEM WITH THE MD-90 AIRCRAFT ON THIS SITE. I DOWNLOADED IT AND IT'S ALL IN THE RIGHT PLACE, BUT IT DOESN'T APPEAR IN MY LIST OF AIRCRAFT IN FS98. I EVEN HAD THE AUTHOR SEND ME THE 95 VERSION AND THEN CONVERTED IT WITH THE 98 CONVERTER. IT STILL DOESN'T WORK. I'VE LOOKED AT EVERYTHING. IT ALL LOOKS LIKE MY OTHER PLANES EXCEPT IT DOESN'T SHOW UP IN THE LIST. ANY SUGGESTIONS? I'VE EVEN DOWNLOADED IT SEVERAL TIMES THINKING MAYBE THE ZIP FILE WAS CORRUPTED. NOTHING WORKS. HELP!!! I DID NOTICE IT HAS ONLY 7 .AF FILES.

A:

Copy the panel.cfg file from the 737-400 to your new plane's \panel directory. Some aircraft come with a panel.cfg file that points to a panel you may or may not have on your system. Causes the plane to not show up.
