The 'fix' includes using 2 AoA sensors. That is not a fix. The ac needs 3, so Boeing is minimizing the cost and impact of the fix.
They almost always disagree, so a 3rd is needed in the decision process. What happens if, like in the crash, one is damaged on DEP?
If MCAS is inop can the ac be dispatched? How does a pilot know MCAS INOP?
If the system is not active until 400 AGL, how does a pilot know the system is inop?
Since the first Lion Air incident was on final, where are the parameters for that?
