So instead of "sole manipulator of the controls" we now have "carried out". Which implies to me that he has to perform all duties of the pilot, including being responsible for the conduct of the flight. Not just manipulating the controls.
You could argue that, but in my book "carried out" is still pretty vague.
Given the endless debates over "sole manipulator", and the obvious safety issues, I wonder why they could not just say what they meant.
Perhaps this is a classic "Euro-fudge". Perhaps they could not decide, so they simply wrote something meaningless and hoped that nobody would notice. I am sure they still got paid...
