Re: Just to clarify what MCAS really does.
From Boeing:
Boeing stated that MCAS was added to “to compensate for some unique aircraft handling characteristics during it’s (sic) Part 25 certification”.
In other words, the aircraft could not be certified without MCAS.
A system that has control authority (even at limited times) should always be treated as safety critical; using a single AoA sensor destroys any notion that it was so considered.
MCAS is is always actively monitoring incidentally.
It will be interesting to see if the low airspeed warnings actually occurred as looking at the flight radar data the actual profile looks quite normal apart from the vertical rate where MCAS quite clearly kicks in.
Initial climb out at 2000 feet per minute seems quite reasonable.
