Actually, there's one current OEB that can't be actioned that way because if you do the initial ECAM actions first, there's a strong possibility of losing both air bleed systems. The OEB is called "Dual Bleed Loss", which is a misleading title which has led a few pilots to think they need to use it if they have a dual bleed loss. It should be called "Prevention of Dual Bleed Loss" because if you don't apply the OEB at the first signs of trouble, following the ECAM will cause the dual bleed loss.
The reminder function is a great tool and I'm befuddled that it's not a standard upgrade across the board. We're trying to get it done on our fleet.
