I know what AoA is and yes, the calculation of AoA by itself is simple, but the corrective measure is not.

Classic 737s climb via trim, not constant stick inputs. This has changed slightly with the MAX but now you have automated AoA correction (involving trim). That's a nasty combination.

That's not nearly the case. MCAS is a stupidly simple system intended to cut in during very unusual phases of flight were a normal commercial flight would not be operating.

> MCAS is a stupidly simple system

So, you have reviewed the software? If it's so stupid simple, why did it kill a bunch of people?

Sigh. I've reviewed almost everything written about the accidents including the information supplied by Boeing to the airlines to explain the function of the MCAS system.

There is no lower limit on the complexity of a system required to kill people.

So, you're essentially parroting Boeing's narrative IMO. Yes, they want you to think that the system is 'stupid simple' and it's 'no big deal, just one little fix' because obviously that's good for their business.

Maybe, the system required for safe operation is not so simple, and Boeing is no longer competent enough to create a system. Perhaps the 'stupid simple' system was all they were able to muster.

Or maybe they forgot to add the flying unicorns to power it.

I'm not sure why you think boeing would lie about it. Or how they'd convince the regulators in two different countries to cover it up since you can see the behaviour by reading the graphs in the preliminary report.
