>If the two remaining disagreed then the system would be disabled.
On Lufthansa 1829, two of the three AOA sensors on an A321 erroneously agreed, causing a system similar to MCAS to kick in[1]
The sensors can also be damaged by birds
It seems like two sensors is not enough; nor are three. I'm curious whether it would be reasonable and feasible to add five to an aircraft
