And the AoA disagree needs to be actually used and not just an "option feature pilot warning". AoA disagree on ground = plane doesn't take off. In flight = MCAS cuts out.

You can't have an AoA disagreement when stationary on the ground. It is a wind vane.

You don't know that. If it's malfunctioning it could be in the electronics and nothing to do with how it operates.

And if it's reporting a difference, it could just be because there's no airflow and the vanes aren't at identical positions. You can't rely on the difference meaning anything.
