If you will forgive me the use of my favourite metaphor; that is a particularly juicy red herring. Just because most of the flying may be done in Normal Law doesn't mean that no flying is done in ALT2. It possibly is more than 10 hours but I don't know. However, be that as it may, a properly trained and conversant crew should have no trouble using the aircraft in ALT2 law. Those who have tried to fly it in such a state and who have posted say that it flies well. It was designed by Airbus to fly well - you can be sure of that. It would never have been certified if it was an absolute pig to fly without protections. Once again it's a training issue which should have been addressed in the simulator. If it wasn't then again it's a training issue. Pause, diagnose (using your instruments) then fly. But then I am afraid that this crew would have flown anything into the ground.
