Oakape;
Re, "Is there any indication that the flight crew on AF447 aware that they were in alternate law? Perhaps they missed that in the confusion & thought they had stall protection."
That question has been dealt with extensively in many locations among the ten threads dealing with this accident.
If they missed it "in the confusion", that is an indication of incompetence, not "mode confusion" - recognition of Alternate Law and what to do about it is a fundamental training objective in any Airbus transition course, and, if you'll pardon the observation, this has been stated dozens of times over the past four years.
