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:> Boeing sells an option package that includes an extra AoA vane, and an AoA disagree lightThe 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.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?
