Fascinating, headsethair, thanks for that. I would say, though, that 'high hover' is not a new mantra. Frank was banging on about it when I did the course nearly ten years ago.
I think (I may be wrong) that Frank used to advocate the 'hockey-stick' approach, keeping the speed on to stay out of the avoid curve. Perhaps there's been a change of mind there.
Most fascinating of all - 55% of accidents happen with an instructor on board. That really reinforces the nature of the work the R22 does.
