That's among the most scary parts I've learned from PPRune. There was that guy doing geometer-work where he had to hover HOGE so that some vertical laser pointer would be hitting the helo's belly inside a 10" x 10" sensor section, hence effectifely staying pinned at some 1000 ft AGL, ROD being 0. He claimed that during this prolonged HOGE he would get inevitably and demonstrably into IVRS.
That somehow doesn't add up to them vids showing the live powerline cleaning stunts which presumable never have such VRS issues, but one truly gets the impression that HOGE has one "springloaded" for VRS.
