GF,
The acknowledged benefits of being raised by PacMan, I guess ....
I'm just glad that I got to play a lot on the 733 ... if it all looked like it was working, one could leave it on and still fly with an eye on the steam data but with some add-ons to make a few mental processes easier ... otherwise the "OFF" button worked real fine and we went back to flying a la DC3 and one definitely was responsible for one's success in life ...
My simplistic view is
(a) under the surgeon's knife, you don't have a choice
(b) in an aeroplane, you can tell the controller what you are going to do, albeit that it might get up his/her nose a tad .. and, of course, most of us have had the occasional need to do just that ... ATCers (and I have more than a few mates in that discipline) are no less immune from errors than the rest of us ..
