The BEA note provided altitude information which means that altimeter data was recorded just as the (failing) airspeed was recorded. So at least one of the altimeters was functioning correctly and though they don't say, I would think all of them were functioning.
infrequentflyer789;
I would perhaps also add "they lost attitude indications and thought they were diving" (somatogravic illusion etc.)
Understand the somatogravic illusion possibility but we have no indications in the ACARS of a loss of the IRSs so attitude information would likely have been available.
I think it is low probability, but PF displays aren't in the flight data, and there is the line in the BEA release: PF said "I don’t have any more indications", and the PNF said "we have no valid indications".
The BEA note doesn't indicate that the "PF displays aren't in the flight data", it states that the #2 CAS parameter isn't recorded which is quite different. At this point I don't think we should put too much stock in the plural of the word "indication". We'll know by the end of July I think.
