Let's try an ON-LINE FMEA (failure mode effects analysis). Over the
next 24 hours, I'd like for people to post their response to the following
questions:
(1) Name one item of electrical equipment critical to safe completion
of flight . . . or an item who's failure presents an immediate
hazard to completion of flight.
(2) List the ways in which this device or system might fail.
(3) How will each of these failures become obvious to the pilot.
Tomorrow, I'll carry the analysis of each response to the next step.
This is just the kind of process we do in the "big" airplane business;
it's a good exercise to know . . .

Bob . . .
