Some great points made above. Thinking back a whiles to my old airlines, we taught how and when to deviate from SOPs. Critical thinking and rule breaking were on the CRM syllabus along with managing an aircraft across cultures. Some airlines introduced checklists with steps, mid critical actions that said...." Fly the Aircraft ".... elec ##...off..reset....."Fly the Aircraft"....
Some a/c manufacturers go very quiet when something happens that they really don't like and then they take years to close off the issue.
A heavy Boeing with its (unheated) ....elevator covered in ice shaking the whole shooting match to blazes on the approach to London. No can't happen.... yes it did.... and there is the picture for Seattle. The heavy boeing with a batt bus failure that tripped off the whole AC elec system with terrible results. Can't happen say the manufacturer...probably Crew error. Not crew error, they saved the day with critical thinking.
Thank goodness for modern CRM training.
