To be certifiable (and more to my way of thinking, cleared for dispatch) the 737 needs two functioning Inertial Reference Units (IRU).
To be certified to fly, MCAS needs to be operational to be dispatched.

I see they have initialized the optional AoA dial on the flightdeck, and a light when AoA does not agree...(at 400 AGL?)

How does one determine MCAS is operational to dispatch? It must be on the ground, correct ? you cannot dispatch with a non-normal condition.
Have they added a MCAS INOP check prior to DEP?
Have they initialized MCAS on the ground (instead of 400 AGL?)
How can you check the operation of the AoA vanes while on the ground? (they all show 90 degrees?)

As part of the 'fix' there will be an AoA measurement shown on the screen. And this means what? As the saying goes, what would you do with the AoA measurement if you had one? Is is it showing the wing AoA or the fuselage AoA? How many pilots know the AoA of the wing vs the fuselage AoA?
Do pilots know the AoA and/or conditions when the engine nacelles provide the sudden pitch up?

How long have pilots been asking for the AoA ?

MCAS relies on the AoA vane measurements, which in reality, ac dont even report the AoA angle (case in point) nor has anyone paid that much attention to, yet now the automation does, and there begins the disconnect.

We are Boeing.
