I have great regard for V F but I can’t completely agree with him on this one !! I have just come back from Bell Academy and those instructors really do know a thing or two and they swear by it . I think they usually only go to 3000 ft min or a bit more but it does work very effectively ( whether that is regarded as full VRS I don’t know ) . I agree with Sasless that we need more than one method . Obviously if you have an obstruction coming up then pole forward is not very clever !!! I believe all the Bell pilots think it is a useful tool in the box . My last comment would be that in 99% of occasions ( VFs one of a huge updraft is in the 1%) you get so so much warning of it you would have to be asleep not to notice ...
yaw , shake , more yaw , more shake , falling feeling in stomach and after all that you are still in early stages !!!!! ( I can only talk about light / medium machines )
