The MCAS failure presented itself as unintended stab movement and the emergency procedure to cover that was the runaway trim recovery.
Boof,The problem didn’t present itself as neatly as you describe.
Salience of the stick shaker must be recognised and the cognitive processing functions that occur in order to dismiss the stick shaker as a symptom of a different failure, also have to be taken into account. This is before most humans brains will be capable of switching attention to other sensory inputs such as the feel of the yoke or the visual of a spinning trim wheel. Channeling of attention is powerful. Often people involved in rescues or intense sport won’t recognise that they are injured until after they have finished focusing on the task at hand, finished channeling their attention. Think you’re different? That’s not very likely.
