If Sully the third and PM are always required only to do what is written up in the textbooks, and no more, and are not required to exercise judgement, then why not merely programme computers to do all phases of flying, passenger comfort, and all other aspects of air travel?
Wingsfolded, we, as professional pilots are required to exercise judgement on any number of things before and during every flight. Exercising sound judgement is one of the many attributes of being a good Captain.
Following SOP's does not conflict in any way with applying one's judgement.
Your comment is meaningless because you misunderstand the concept of SOP's. The military have strict SOP's, the airlines (good ones) have strict SOP's. The crew of the space shuttle have strict SOP's.
It's the way we accomplish the task in the safest and most expeditious fashion. Nothing to do with following rules without question.
