Pilots have been stalling their planes out of the sky a lot longer than the electronic PFD has been around.
Was there a period, ever, in the days of the big round dial where there were 4 stall-crashes in the space of 5 years (to scheduled passenger flights)?
There had been some cars with digital speed display, but they never succeeded enough to become standard.
I read something the other day about the automobile industry, having gone to tape-like instrumentation, now going back to dials. Perhaps someone here knows more about this. If true, if wonder if that industry, unlike our industry, has actually done its homework!
