[QUOTE=Clandestino "Descend, descend, descend" was issued at 14:21:41[/QUOTE] - you are mixing up your RAs. This one (short term) was caused by the descent of the traffic above, not the later climb of the TC.
The 'desensitisation' of which you speak involves, I believe, an airspeed or mach input? Not much use in 447's case. I still feel uneasy about some underlying similarities between the TC and 447 - turbulence, a speed issue, A/P and A/T disconnect followed by a rapid climb. Yes, I know what BEA say. I still think it significant that without rearward stick movement in AoA law the system maintains alpha prot - the reasoning for this I cannot understand. Do we know whether 'AoA law' was triggered for 447?
