Interesting title caught my eye.
"They are complicated to use, subject to failure and obsolescence. Why then do we not move to a 'heads up' display method of operation?"
I fully agree with the first sentence, but I don't understand what the " heads-up display method of operation" refers to? Is that a diagnostic tool the Air Force uses via sensors with computer logic running diagnostic analysis? MTH's DCS has some diagnostic features, but I have to say staring at a screen and thumbing through selections via multiple buttons is not my idea of fun.
