The question is, and i asked that before: Had the the crew a way to recognize the exact state of ALT Law, in this case ALT2B, which differs significantly from a variety of ALT Laws, and did they?

The listing from Turbine D does not offer any detailed information into what kind of ALT Law the FCS in the mentioned UAS events reverted.

We might as well have here with AF447 the only case, where ALT 2B was triggered and in all other cases more protections had been available. Thus creating a wrong mindset with the PF (...Alt Law, no problem, business as usual...)
