Whatever the theory about increased risk, the US age rule works works in practise. Same in Australia I think. So two of the biggest countries in the world with lots of helicopter ops allow single crew after 60 but that's not good enough for the British CAA that stops single crew at 60.
The stats don't show any evidence of fatal accidents caused by 60+ pilots having heart attacks.
Sure, have more frequent medicals, but the British rule means the end of many helicopter pilots careers at 60.
