Displays...
I was looking at buying a helicopter...an IFR Helo..with a dead flight director..
I considered one of these little PFD things, SANDEL? Anyway...my goal was to cram as much info into a tiny little screen for the least amount of money.
So there is one type of efficiency to shoot for. Anyone who has worked an MFD understands whether a composite display will work for them or not.
Doesn't make much sense to change everything...best to keep it safe, understandable, but the idea of colors changing, and putting more info on the screen but being able to take it away, if you don't want the clutter, I think, is a good idea.
