"No problem flying downwind..." We all know that. We all do it. But ask yourself, given the status of this flight and the weight involved with a high DA, would you?
Or even, "is it absolutely necessary to be downwind?"
This pilot needs to be taken to a wire fence and taught how to take-off like a bird - downwind. Get the feel. Then try some downwind emergency stops (where the last thing you ever do is actually land downwind). Then ballast up the same helicopter and try it all over again.
Basic, PPL stuff. Every expert pilot should know this and have hours of it.
And only expert pilots should be flying aerial work tasks, let alone charter.
