Could you not stall an A330 in Normal law if you got it into a particular approach attitude, and once stable, poll the throttles to idle while trying to hold the nose up?
No, I don't want to try this. I doubt anyone does.
As I understand the control logic, an input to "counter to the nose down pitching moment associated with power reduction" would be called for, but so also would a command "don't stall so pitch the nose down to avoid stall."
Are you sure the latter gets priority? I would guess it does.
That considered, the significant deceleration, that close to stall margin could change AoA rather quickly into stall before the nose down commands kick in ... or, maybe the computer is that fast, and the nose dumps to avoid stall so you crash nose first thanks to that input.
Are we discussing something like "bleeding practice" here?
