I am a bit non plussed here why a new fresh faced F/O would not know what to do. The element of if in doubt Speak up is covered in every HP&L exam from PPL to ATPL.
I accept commercial pressure and not making too many friends. The fear of being stuck as a 2 ring F/O for years or being pushed out of the company but in all realit if you flew with a drunk Cpt you would got no respect from your bosses or colleagues!
I guess a Journo does not need to pass HP&L!
