> Totally out of my depth here, but how is it possible that they "didn't tell anyone" about a feature so crucial, how could pilots not know how the plane's computer will behave in such a fundamental, non edge-case scenario?
I couldn't even hazard a guess. Boeing told the Brazilian authorities about it. See the table on Page 18 under MCAS.
Note that MCAS is distinctly absent from the difference tables (also) on page 18.
The FAA signed off on the NG to MAX training as "B" level differences. This means no sim time necessary[1] (although apparently American Airlines doesn't have a MAX sim in the first place). The Brazilians were made aware of MCAS and thought that also qualified as a "B" level difference. The question then is: did the FAA think MCAS constituted a C or D level difference?
