Just having a new procedure in the books does not mean that the pilots know (and understand!) it.
General comment, ie not directed at this mishap specifically.
For us to accept such a statement is to accept that the standard of professionalism amongst working pilots has plummeted to an utterly abysmal level.
A bog standard pilot would be expected to know his relevant Type books. If there exists confusion, that would be referred to the operator's specialists and, if necessary to get some action, the relevant pilot union or regulatory agency. Sometimes one has to stand up and be counted, especially in respect of aircraft commanders.
Then again, the environment may have changed since I was in the sharp end ..
