In any case, because the material cost of software is $0, the cost of
verification would have to be very high indeed before a point would
reached, beyond which, it did not make sense to make the software
because the market could not support it.

I tried to resist jumping in, but having read through many of the posts
only to see you wind up where you began is incredible. if one more voice
saying that you are grossly missing the fundamental costs involved in
software development helps to move you from this position, then perhaps it
won't be wasted effort.

GA is a small market. Too small to warrant specialized development of much
of anything, which is why most of the components are either used or
spin-offs from other areas of aviation. Comparing it to the _general_
automotive market is completely off-base, as even a single model of a
single brand in a single year will have more units in the market than all
of GA.

So, to think that a body of expert programmers will somehow collaborate on
systems that, at best will be less reliable than the pulley and wire that
they replace is an unrealistic fantasy.

BTW - if you think that "the material costs of software is $0", let me
know where you're getting your language compilers and hardware to create
and test your code. And, don't tell me about "Open Source" options,
either, unless you want to increase your development costs by a factor of
100 or so.
