even a relatively straightforward, albeit critical, task like throttle control is likely to use a sophisticated RTOS and tens of thousands of lines of code.

by my recollection I have seen ~5 cases with a RTOS that should not have had one and one case w/o a RTOS that should have had one.

The stupid mantra "a programmer is a programmer" have led to more shitty embedded code than anything else.

I was, some years ago, called in to help some programmers (found out they thought everything was as they thought) get code banking to work. I threw the code out and ended up with a solution in the 8k rrange.
