Working in the computer
field I was wondering why so much time in the aircraft industry is
concerned with minimizing the mean time between failure (MTBF) on a single
component
Tim,
I'm also in the computer
business.....and that is part of the reason there is no chelton efis in my
airplane. but I digress.
I may not be addressing your
point directly but I think the cost of making an airworthy part is not just
about MTBF against the original design. I think more of it is
figuring out if the part as designed works properly before it
breaks. e.g. does your de-ice system really de-ice when it IS
working? does your alternate air source actually not clog when you
need it? does your only landing gear extend when you need it?
18 months ago I was pretty disillusioned with the whole certification business
but now I am much more appreciative of it. It does somewhat improve
the probability that the stuff works in the first place.
