It would be useful if you had the time to go from the standard nav page to = the backup instrument panel page while the airplane was going through some = pretty good gyrations and recover it to S&L flight. Can you do that on a = 396? The question you have to ask yourself (from the movie "Dirty = Harry") is "do you feel lucky?" or have you practiced flying off the 396 = with nothing else operating.

Designing one of these panels, IMHO, is an exercise in NOT putting all your eggs = in one basket.
