In an emergency, not knowing what to do comes from not knowing what you face. Not knowing what you face is caused by a lack of, or misleading, cueing.
It is not helped by not knowing what one should do if one knew to do it. That is not aided by having to read something to try to understand what it is one does not know. If three of you do not know, the airplane will do what it does, whether you know what that is or not.
If you do not know what the airplane is doing, you should be home playing rummy. If the airplane is coy, or misleading, that can be judged as lack of skill in understanding what it is supposed to do, unless something comes up that the aircraft cannot do, in which case the three who do not know will be blamed for not doing what they didn't know to do in the beginning.
The fact that the airplane and by proxy her designers, did not know, is not important, for they are not present, only the evidence of their work is.
The mistakes they made can be corrected with new work that can be added to the aircraft and utilised until the aircraft once again comes across something it cannot do, and the pilots will be required to understand immediately what it is they do not know, and most likely were not carefully taught.
