Abnormal Law.

PJ2:
I didn't go into 'Abnormal Law" as stated by BEA and 'confirmed' by this data:
If CAS < 60 Kts AOAi & AOAc are set to 0° and SSM (System Status Matrix) is set to NCD (No Computed Data),
this is also valid for TAS 0 Kts if CAS < 60

If CAS < 30 Kts it declares itself invalid and outputs 0 Kts and NCD.
........
(Stall warning is generated by highest AOA and not the median value)
This means actual AOA could be indeed 40° while not triggering ABNORMAL ATTITUDE LAW due to a median *AOA* (ouch, made a mistake here, should be CAS) value below <60° (resulting in a AOAi of 0°) as already mentioned in the BEA ‘leak’.

@PJ2:

would this be a correct understanding of what you meant?

and

@Chris:
Please forgive me for offering readers a warning on terminology here.
Exact! Thx to you both for making this clear and with apologies, english is not the native language.
