Go on then, explain why you believe something like MCAS is too complex to make properly. Mismanagement is the root of these problems, not the supposed complexity of the problems.
MCAS was one flight control law, a one that was poorly conceived in the first place and then botched in implemention, but still only a single flight control law. If you think that such a system is too complex to created properly, then please tell me how many thousands of engineers must have been on the team that created the first all-digital fly-by-wire system for an aircraft. That was a hell of a lot more complex than one flight control law on a 737, and they were actually doing something new back then. Thousands, why it must have taken tens of thousands of people amirite.
When did I talk about any specific system? You can’t make a toaster without at least five databases. You can’t change oil in a car without consulting the internet because there are 400 oils and special mfg requirements like a programmer to reset the counter or to run a replaced oil routine.
It’s not my fault you can’t think beyond Boeing.
It’s the whole world, and you are just one of the people that even if it is pointed out to them can not see it. Because like I said, you haven’t made anything to see the issue.
