don't know if this has been asked before, but it would be nice to have optional audible reference when doing CDU inputs in NGX like MD-11.

Can those buttons actualy be heard in a real cockpit?

Hey Paul! Those sounds are there. If you clcik the CDU buttons when the airplane is cold and dark, you'll hear them. The reason you can't hear the click sounds during preflight or the flight itself is, according to Ryan, that the CDU buttons make very little noise in the 737 and when you add the engines and cockpit sounds over, you almost can't hear them, if at all. I haven't seen any real pilot, or anybody else, actually, complaining about those sounds, so it should be right.

my mouse clicks enough as it is i dont need any more clickin.
