I fail to grasp that. What is wrong with the following description:
a) we hover OGE at 80% power
b) setting power to 77% will start descent, with an accelerating(!) rate of descent,
e.g. VSI needle will slowly wander(!) towards max descent
(like free falling with the rotor downwash compensating almost all of earths gravity,
thus lift force < gravity force, hence we will accelerate downwards, I get that part)
c) we restore power to 80%. Momentary sink rate is preserved,
won't increase and won't decrease, e.g. VSI needle negative, but steady.
d) we raise power to 83%. Sink rate will reduce, VSI needle still negative, but starting to climb.
e) when we reach sink rate 0 we could reduce power to 80% and HOGE, or leave it at 83% and start to climb.
You were insinuating c) to be wrong. why is that?
