Like already said in this tread before, this subject "VRS" has been discussed before from just about every angles by a lot of knowledgeable people (and there are in pprune) that went from the simplest explanations to the more elaborate ones, from the practical side of VRS to the theory side of it.
The consensus here seems to be that VRS is a dangerous condition to be avoided, if not recognized or understood or reacted upon it could end up in an accident and i am in agreement with this, being an experience (39 years in this) VFR, utility and VertRef pilot all my career I have experienced VRS many times during my carreer, almost unavoidable with more than 8,000hrs VertRef.
But as I said earlier VRS has been discussed from "just about every angles" but not all of them, I never heard anybody say anything good about it, so my question here is.
Does anybody here sees a good practical/useful side to VRS? just asking.
