Back to the AB experts please. Again apologies if I am going over old ground, but the reading of the thread remains a challenge.
I understand the ABI instruction is to 'respect the stall warning', but to me it looks as if there will not be one?
From my reading of the 330 FC section, it appears that in ALT 1 there will be an IAS driven stall warning, but in ALT 2 with 2 ADRs out there will not, and with 3 out there will be also no overspeed warning.
Obviously there cannot be a reliable 'overspeed' detection, but I cannot see why an AoA triggered stall warning is denied in a worst case scenario of no IAS to work on. Are AB pilots actually happy with this or should the warning be available? (E&OE of course
) Surely this is the only 'long-stop' left to a crew with multiple IAS failures?
