To off it pilots loose all electrical controls on the stab, and MCAS is prone to single AoA failure, that is the reason why it was classified as a augmentation system...when in my opinion is a stall ID system... cutting corners to solve major issue
Stall warning OR identification? You may want to add avoidance or augmentation device since it applied control input. Now let me help you with the warning or identification part......MCAS neither warned nor identified pilots of a pending stall situation. Hope that clears it up.
The MAX needs to be re certified from scratch !
