Helicrazy . Don't worry , it's very easy to be misunderstood on these forums but I really tried to make it clear that this was just positioning ! The answer is yes I have also needed to hover taxi in very low viz but , as with the others , this was after very bad decision making on my part and was part of the process of finding a spot to land , ( the field I chose was full of cattle and so was the next one .) I would also point out that in the event of you crashing in this process you would at least be only doing a very slow speed so chances of survival would be good . I guess the point some of us have wanted to put forward is that as viz decreases , so should your speed ... So eventually if you have been stupid enough to get there , by the time the viz is 100m or less your speed should be 5-10 knots and not 100 knots !!
