This is what we need:
A voice that appears to come from behind the pilot--preferably a shrilly female in her early-mid 60s--constantly nagging with passive aggressive suggestions as to what to do next, or giving annoying reviews of maneuvers recently executed.
"That Split S made me drop my glasses!"

For those of you who make your own sound packs, I think that a nice Brooklyn accent option would be just fine. A chinese accent might be a bit much, but just on sundays, why the hell not?
