Stall Warning

jcjeant:

Quote:
Aircraft certification in Europe (CS25), which says in paragraph 1309 :

Quote:
CS 25.207 Stall warning
(c) Once initiated, stall warning must continue until the angle of attack is reduced to approximately that at which stall warning began.
What about Airbus A330 ?
The Stall Warning logic itself is not at fault here.
It's the 'reducing' AoA value to 0° when CAS <60Kts by the ADIRUs which stopped the warning.
(We know they have changed that, don't know if its a part of the optional BUSS mod or if it is a separate -mandatory- mod)

Anyway this will be a legal case, who's to blame?
and I think we already suspect who will be blamed (for operating outside specs) at the end.
