Dear Mr GreyHorizonheli,
you are arguing from an academic point of view. It you are such an expert, please justify your standing.
Having flown own more hours than I care to remember with Crab, he is talking more sense than has been espoused on this topic than many.
You may be a mathematical genius, but you appear to have have no practical experience of Winch Operating environment.
This topic has been hijacked by yet another bunch of social media experts who appear to run their lives via PlayStation. If I am in error, I appologise, What makes you such an expert?
