I saw the hearing and found it interesting.Cruz asks Erwell towards the end if its true
that there was no information on MCAS provided to pilots.Erwell fumbles a bit and
then responds that the errant MCAS intervention is runaway trim and that is already
covered in the QRH under the Runaway Stabilizer NNC.Boeings AD in
November says the same thing.I think the Committee's investigation will center on this
argument plus the single sensor issue and the controversial decision
to have MAX added to a 1967 certificate as amended type with flimsy
self-administered ipad training.
I think the AoA presentation on the PFD is a red herring but agree that the
dispatch light for AoA disagree is a critical safety feature and should be fitted as
standard equipment.
The stick shaker in my view is still the golden nugget here as it blocks
the auditory channel of both pilots,masking trim runaway and leading
to startle factor for some crews.
