This is not to bug you but you write above that, "I've heard of severe turbulence that can generate sufficient G loading to put you at zero G".
In 'The Art and Science...' you quote that, "I have never seen a gust that can give anywhere close to zero G in a helicopter, and I've been in some pretty strong turbulence in lots of helicopters."
Should I be worrried in my teetering head machine round the back of the hills or not? In a brisk wind it seems to get towards a small positive G sometimes, can it go negative?
Thanks
