Hi Claus,

adding support for more complex cockpit instruments, like the CDU, 
indeed sounds very exciting! And I think we have a lot of users here who 
enjoy advanced and realistic cockpits. So any help in this area is 
highly welcome!

I'll hopefully find some time during the next days to test and look at 
your CDU. The only thing which generally concerns me about larger Nasal 
additions are some unresolved performance issues. Will be interesting to 
see what impact the new CDU module has.

Anyway, performance issues might also be topic for the next few days at 
LinuxTag. I hope to see a lot of active FGers in Berlin.
Anyone else: don't forget, it starts tomorrow/today - and a visit is 
worth it:
