Crab, technically he isn't in the H/V curve, which is for level flight with the power to stay there.
This is a low-power descent, a different scenario for which the manufacturers do not produce a graph.Way too many people try to superimpose a descent onto the Curve, when it ain't applicable.
I have to agree that skooching in at 130kt (just slow enough to get the Dunlops dangling) and then doing a smooth 180 quickstop to terminate in a perfect hover over the pad is very satisfying. The Sydney control tower even said "Gee that looked good" on one of my better landings.
