AoA indicator is a mandatory solution after the AF447 loss of control, that has already been said by some of you.
But three systems (Airbus) may be replaced by five (Space shuttle), to have a better resolution of systems voting : With two pitots tubes blocked by ice the vote among three says these two are good

The vote among three is cheaper, the vote among five is much safer !
