Not a flame just looking for clarification.

Induced flow, air entering the disc from above the POR.
ROD with IAS= inflow angle, air entering the disc from below the POR.
How does the diagram represent anything to do with Auto? Given thats what we are talking about.

EC is the only post that has actually explaned "inflow angle" which is responsible for rpm.
Of coarse other credits to Nick, Crab, talking about weight increase, what will this effect? ROD of coarse for the same given IAS increasing the inflow angle and so RPM, thats why we raise the lever to add drag pulling the TR back in line and so giving more lift to over come added weight as we hold rpm.

During the flare you increase in inflow angle by a massive amount, the weight of the machine apposing the direction change your trying to make forces this angle increase, or eat more air" as Nick said.
I also agree with an earlier post that Coriollis has only minnor effect. take it easy on me...
