@ Mr O

When speed did get below 60kt at some time (which it must have done to inhibit warner) why did that alone not force change to abnormal attitude law of and by itself given the 'or'? Judging by the time the stall warner was silent I would have thought that it was for a long enough period to exceed any time threshold.

Would a change to abnormal attitude law trigger an acars msg ?
If speed itself < 30Kts it set itself to NCD.
Why? the only reason mentioned in the docs. is due to -accuracy-.

The 2nd STALLSTALL started @ 2:10:51 AOA 6° (AOAsw 5.2° later 10.8°)
and sounded untill several seconds after capt entered the cockpit,
at the same time all recorded speeds became invalid (NCD) AOA then exceeded 40°.
Once again AOA for AOAsw is the max of 2(3) values, AOA (and speed) for FCPC the average(median).

No, this law will not trigger any message, the only clue will be the absence of autotrim and indications (if present).
