Hi,I am new to all of this, but I am thinking of building an A320 cockpit based on the PSS Airbus or the A320 PIC by Wilco when it is released, and I need your help.What I am unsure about is how to control LED's eg red and green for the undercarriage, all of the 'fault' lights on the overhead etc. If I were to use EPIC, how does EPIC interface with FS to determine the status of say the 'APU starter switch light' or the 'external power switch light' and so on?Many thanks,Nathan.

Nathan,Visit Pete Cos' site at www.a320project.com. Or visit his FDS site. There is a link on his main page. I think you will some interesting things there.Richard

Or take a look at the thread in this newsgroup on 7-segment displays. The FSDigit file referred to can be used to drive up to 4096 individual LED's for exactly the purposes you describe - I'm doing just that in my own A320 cockpit.RegardsDave T
