737 Max Explanation by a Software Engineer
I'm an assistant professor of aerospace engineering and I find this analysis quite spot on, in which this is representative of a much larger issue of economic and regulatory negative incentives, rather than just a "software issue" as some news outlets have reported. What I find downright criminal is this:<p>> <i>Boeing sells an option package that includes an extra AoA vane, and an AoA disagree light</i><p>The fact that the redundancy of a sensor on which a system capable of sudden, large control inputs relies is an optional package to be purchased separately... I simply  have no words.<p>How was this package advertised in the brochure? Pay extra and when the airplane nosedives at high speed, this useful indicator will helpfully warn you it's because AoA reading disagreement?
