VicMel, #2858, thanks for the reply.

So with my simplistic view the problem appears to be random, chance. Alternatively, as a sceptic, why 2 aircraft in 4 months, whereas the remaining fleet …
OK, so this is the nature of probability, together with the ever-increasing fleet size.

Thus the next question is where a ‘good’ AoA software fix could - should be made, but if not … at least the output of MCAS should be limited.
And if AoA is not fixed (still probability), there could still be problems with speed pressure error correction, air-data disagree, feel, and low speed awareness, but will these events be no more than experience in previous 737s, or if it still is an issue with the Max (inadequate software / FGC ADIRU overloaded) then there will be an increase in disagree alerts due to ‘corrupt’ AoA.

I may be dancing around the same tree as in my post in the other thread - #485 Boeing 737 Max Software Fixes Due to Lion Air Crash Delayed
Where is the value of AoA sampled by the FDR; would this clarify current understanding.
