In post #38 I have termed the dual input or noncoupled side sticks as the Achilles heel of Airbus. So I haven't denied that. I had commented on 447 thread that even if it was empathized in classroom that in alternate law you should not pull full back stick even with GPWS could have saved both the aircraft. Airbus by it's philosophy is automation. Now it has come out with alternate speed where with unreliable speed situation aircraft tells pilot it has switched to alternate speed and he doesn't do a thing. Accidents happen even with everything in place as it should be. My point was 447 has been discussed threadbare and we should not be trading the worn out path.
