Fear of Fear. Bonin's initial actions were not delayed by time spent in assessment. It is easy to say, "...the aircraft Nose was down, and it was in right roll..." So. Immediate inputs? Perhaps. Was stress level high?
It is common for our "survival" response to react quickly, to not allow a situation to "get away from us...." Additionally, abnormals are almost always experienced in the sim, where the expectation is for quick solutions....
It is not uncommon for one to act quickly, precipitously, to avoid fear "taking over".
The A330 does not Stall like a glider... Not at all like a glider.
A question other than "How could the pilot input so much nose up?":
How did he keep it right side up, directionally stable the entire time? The Stall Is benign, so much so....
Not only does it stall gently, it is so easy to fly whilst Stalled....
Is Recovery from Stall in the A330 more frightening than descending right side up at 7000 fpm? Does it present such an intimidating prospect in recovery that falling is the preferred option? Is recovery impossible, regardless the altitude available?
