Hyperveloce:
In the Air Caraïbes case...
Air Caraïbes is the best documented sequence to understand what happened into the cockpit, but this is not fully comparable to what would be the ACARS sequence of this flight. Then, the difference should be notable in term of what would be triggered by the CMC (Central Maintenance Computer) e.g. when or what ACARS will be triggered and time stamped?

Some may be triggered by pilot fault clearance thru ECAM procedures (like NAV ADR DISAGREE). This is obvious from other reports when ECAMS warnings are showing by intermitence when speed (IAS DISAGREE) or other probes are showing large fluctuations. Each warning doesn't mean an ACARS is automaticaly triggered as it may be cleared by itself.

Beside, there is some difference with AF447 about the initial flight parameters (lower speed at Mach 0.80 and A/THR already OFF before the event). The TAT probes also seems to be frozen and the event didn't last more than 2 minutes. But other parameters are the same: altitude, weight (206 t), flying in tropical weather.
