New element?
The drop of 300 ft in indicated altitude as a consequence of a drop in the measured total pressure is apparent in AIR CARAIBES memo dated 01-12-2008. I discussed the reason for it in my post on the AF447 thread no.1 (p.193, post #3856, 24 july 2009), and BEA explained it again in para. 1.6.11.6 'Consequences of a drop in the measured total pressure' of their Interim Report No.2 of December 2009.
