"What? Like coming to a hover at 500 ft agl in a Jet Box and then decending straight down?"
Sometimes yes, with a 150' line and 100ft. timber, I'll often do a 300' vertical descent in a 206B.
But at max gross with an internal load at high DA I'm making a smooth, shallow approach to the LZ, hard to arrest a fast descent rate in that scenario with a steep approach.
