FCeng84,

I have a question. With AoA sensing being such an important element in the flight control systems of modern aircraft, why did Boeing not fit three AoA sensors so that a simple voting protocol could be used to eliminate the faulty signal? Was this to keep the design simple? Or was it to remain within the logic of the previous 737 variants so as to be able to retain the orginal type certificate and thus save the expense of re-certifying the aircraft?

I am still astonished that the failure of one component should have had such deleterious consequences.
