Don't be silly Cecil. You can't teach that which is impossible. Remember the old films where the hero would be heaving back on the stick with both hands as the noise built to a scream and it all ended in an explosion. Once you lose any of your basic instruments it is all over. If by chance you survive you can write a breathless article for the CASA crash comic telling how you were late down wind at Bankstown in your little chugga lug on a pleasant afternoon when to your alarm your dynon went dingle. No ASI, no angle of attack meter. Stuck in that fuzzy 80kt range between stall and VNE with no idea which end you are at. What do you do? Declare an emergency. Perhaps they will clear you across to Kingsford Smith for the longer runway. But no, it gets worse. Your auto piot has decoupled from your Garmin. You will never find the place. Only one way left to save the day. Deploy that rocket fired parachute that you were smart enough to install.
Seriously though, I thought this thread was about minimum panels. While the aircraft is being flown along by the auto pilot and the pilot has his head inside scrolling through pages on the glass display finding what the CHT trend has been on No 4 cylinder for the last half hour, what is happening to the external scan. Perhaps a very large strobe would be a good bit of equipment. Help the rest of us to see you coming.
