Surely the old addage of "there are no bad students only bad instructors" needs to be considered here. If an airline recruits a new pilot, be he ex-mil FJ, ex-mil truckie, civvie self improver or a transfer from another airline each will need a certain amount of training, some more than others, but not all the same training. If we were all the same and could be trusted to all do the same as the next pilot in each and every situation then training would be easy.
If one pilot of whatever experience and whatever responsibility can ever look at another pilot with less experience and less responsibility and say to himself "I have nothing to learn from this persons experience" then he is at wat. We are all learning (or should all be learning) from each and every person we encounter in this business.
A vast amount of effort, time and expense has been expended to get each and every one of us into the profession or pastime of aviation and to date no one has ever learnt all there is to learn. There are many ways to achieve the objectives, ops manuals, order books, rules and regs are all there for the guidance of the aircrew, but there is no substitue for experience. Ain't no book ever been written wot tells me what to do in every situation.
Sad to say it is too often the case that a transgression of the "rules" is viewed as a criminal offence rather than viewed in the context of how and why it occured.
Just because the books says how to do it does not mean it is the only way to achieve something, reasoned, rational and free thought should be a commodity to be cherished.
Horses for courses.
