>MCAS is quite safe FAA emergency airworthiness directive 2018-23-51 [1] We are issuing this AD because we evaluated all the relevant information and determined the unsafe condition described previously And what it describes previously is MCAS when receiving erroneous AOA sensor input. Also, your post basically says MCAS is safe when disabled, because in the very same sentence you claim it's safe you also claim the pilots are supposed to know how to (indirectly) disable it. That's almost comedy. >why the pilots did not take this simple corrective action It's a valid question why they didn't take corrective action; it's insulting and asinine editorializing to call it simple.
