Zorin_75: From an engineering perspective; invalid (faulty) air data from non- design-redundant sensors appear to be the weakest link imho, triggering a cascade of errors thereafter.
Band-aid, extrapolated solutions just don't fly with me. If someone is going to give a pilot or a computer Air Data, then sure as aunt betty make it dependable, fail-safe Air Data. It's really just that simple. Alternatively, a crew of two pilots, and MacGyver might suffice.
