MM43:
Thanks for re-posting the list.
I respect A33Zab's obvious knowledge, but that list leaves a lot to be desired and has some flaws of logic and terminology in it if you were to use it for training, i.e.
ALT1A:
As ALT1 but Stall protection is lost.
ALT2A:
As ALT2 (Stall protection is lost)
...as if stall 'protection' (wrong term) is available in ALT2, but not lost until reconfig to ALT2A?? In any case both stall 'protection' & theta protection take a hike in all laws other than normal, so 1A, 2A are what exactly?? Just vanilla 1 & 2??
My question regards the difference in failure modes that would create one or the other level of reconfig. I would have thought that 2A & 2B are a function of how many ADR's get flaky, i.e.
1 flaky ADR = continued Normal Law
2 flaky ADR = ALT2A
3 flaky ADR = ALT2B
I guess I'd like to know how do I then get into each of these conditions and then how do I recognize which one I have, which ones 'latch', which can be recovered to a different level of reconfig, or do I even
need to know any of this?
Simulators generally only provide a limited range of constrained failures to achieve one or the other reconfiguration level for training, so does the available documentation need to be enhanced?
A33Zab is an excellent source of info, but there's probably a lot of A330 pilots who don't even know he exists.
