Iceman, I remember those days, here was my work on a PC21 built for Ali where is used working screens for the front cockpit console - it was fun indeed.
The original cockpit was fairly basic in its details but it made for a great result - early days and wish these guys great success with what looks like a really superb product.
Here is a link too to the final PC21, the screens are simply cycled on a timer - original screen shots were supplied by Pilatus in Switzerland too
