That G limitation only applies in Normal Law however. Once you're in Alternate, roll is direct and the calculations can no longer be applied to limit the maneouvre.

@HN39

While you're right that preventing a stall in the first place must remain a priority, I believe that Airbus and Boeing collaborated on providing proper stall recovery training for airliner crews. What bothers me about the AoA indicator is that while it would certainly be a help in a situation where the pilot knows how to use it, we're dealing with a situation here where at least one pilot was unable to use the basic panel to diagnose and recover from a stall.
