To be fair, I accept Tourist knows more about operating aircraft than me. Of course he does. The difference is, when I spot an obvious question like that I ask those who should know, I don't dictate the answer. Nor do I automatically rubbish them if they provide an answer I don't understand. I await an answer, or an opinion, by the way. Should be a no-brainer to a Sea King operator who is wholly familiar with all those new systems and changes in operating procedures brought about by a completely different Statement Operating Intent and Usage. Or maybe not, given the necessary contract was cancelled on the grounds they should just make up procedures on the fly!
