In February 2009, at the request of Airbus, Thales carried out a comparative study of the behavior in icing conditions at high altitude of the two standards, C16195AA and C16195BA. This study concluded that the C16195BA standard performed better, without however it being possible to reproduce on the ground all the conditions that could be encountered in reality.

Preliminary results of additional wind tunnel testing conducted with the C16195BA probe during August 2009 are consistent with the qualification data of the probe and have not identified any safety issue regarding the probe behaviour within the icing envelope as defined in Appendix C of EASA Certification Specification (CS) 25.

Science can’t reproduce the problem.

It would seem that its a supernatural problem then.

And either AB or AF developed procedures to address the problems encountered on various flights with respecting unreliable airspeed.

All three of the pilots went through the required certification training in sim post Dec 2008. The most recent sim training was performed by one of the AF447 pilots was Feb 2009. They were ready, willing, able, prepared and alert for all contingencies on that fateful day.
