Craig. I would check this out for you but I'm no longer  prepared to download big files I don't want myself. On my 56k connection anything over 10 Mb is out.

The Jet Provost appears to have its own panel so I assume it's included. Make sure you installed the gauiges properly. There are 2 basic types of gauges used in FS2002. You will already be familiar with the conventional GAU files.
Some 3rd party panels use the newer XML gauges. These also come in 2 types - the CAB files like the defaults or sometimes configured in an ordinary folder. Both should be pasted direct to FS2002\GAUGES. Do NOT unzip the CAB files or they won't work. I don't know if any of these later type gauges are used on these panels. Read the instructions carefully & make sure the gauges are installed correctly..
