How a dumbed down calculation helped Boeing certify 737 Max jet
As Boeing and US regulators reviewed the 737 Max design before its 2017 certification, they calculated how long it would take pilots to react to emergencies. But that scenario wasn’t an accurate representation of how the plane behaved in 2 fatal crashes that have led to the worldwide grounding of the jet. The analysis estimated that the automated nose-down commands seen in the accidents were more than 25% less powerful than in reality. This detail of how the FAA approved the plane was contained in a highly critical report released Friday. The Joint Authorities Technical Review, a panel of international aviation experts, concluded that such missteps were part of a broader failure to consider how pilots would react to a malfunction in a critical redesign on the plane. <br/>
