If you use the EN 2 cockpit voice, open your F10 map while flying, if something locks you up, you can hear a mouse click, and then the voiceover tracking, tracking, tracking. You can only hear the mouse click in the F10 map because you can't hear your jet or other noises. it's pretty subtle and you can't hear it while actually flying.
I don't know if that institutes a bug report but I figured I'd mention it.
