MCAS was SW that was created to avoid the additional training that would have been required for pilots to get a new type rating. Then it was so poorly documented that pilots weren't trained to deal with failures (or even know it existed for some). A badly implemented solution to avoid training.russ_watters said:MCAS was mainly a programming problem. Better training might have been able to overcome it, but the root cause was the program reacting badly to bad information (a failed sensor).
Run-away trim is a failure mode in other aircraft too, and pilots should be trained to recognize and deal with it regardless.
Also a bit of poor system design to rely on a single AOA sensor and then have SW that couldn't recognize non-sensical data.
