I think the 727 stall and the same stick back behaviour from the crew finally puts the technology argument to bed. Thanks jcjeant
I am very sorry but I do not quite agree, IMHO.
In the case of that B727, the pilots were erroneously misinterpreting a "consistently" high-speed information given on all speed indicators. They were "tunnel visioned" for the same interpretation of a "high speed situation". And they were all dealing with that false high speed situation. This is consistent with a "there's the high speed mach buffet" statement of the co-pilot.
Later on, the captain "understood" they were on a stall and asked for flaps 2º,but failed to properly use ATT indicators.
In the case of the AF447,
they had no clue of what speed they were flying. That's when you turn on to the "feed-back" of your flight controls. When there is nothing more one can rely on, one would tend to feel the aircraft. I do concede however that there are a lot of common errors in both cases. The first ones being not to follow ATT indicators and SOPs.
