In Air Force pilot training we had to do a blindfold cockpit test. With a helmet bag over your head, the instructor would call out a switch, gage knob, etc. The student had to put a finger on it first try. Since then, I've always tried to know my dash that well. Helps in the dark and when you need to adjust the radio while throttle steering through a high speed left hander when your eyes are otherwise occupied.....
