Starbear, “- the pilot does in fact have another tool with which to contain the pitch up and that is the reduction of thrust in conjunction with pitch inputs.”
You appear to overlook that the GA was in response to a Windshear alert, which in general (overwhelmingly) requires maximum thrust.
At some point there may be a conflict between reducing thrust as judged by the crew in the actual conditions, and the operators SOP, - cognitive dissonance - mental effort, confusion, distraction.
What do operators teach and mandate by SOP ?
What advice do operators provide for reducing thrust after a Windshear GA ?
