alternate law: I thought there was a line referring to an auto-correction to prevent overspeed. I can't find it anymore. IF the PF behaved that way, it looks like a plausible scenario.
I've been in several deep stall scenario's in normal law in the sim, when preparing training scenario's in different laws. Everytime the stall would be uncontrollable, the high THS setting (max) was the cause.
There is not much THS awareness among Airbus pilots.
