Hi Crab,
yes, now that you mention it, recirculation was one of the explanations given for 'power settling' by one of the more authoritive sources I know. Someone else said that it was coming in to land without enough power but I think that's just called 'bad power management'!
Just to add fuel to the fire here is an excerpt from an article on VRS by Ken Armstrong that appeared in Issue #11 of Pacific Rotors...
"When More Power Seems Like Less - There is some disagreement in the rotary wing world about the terms settling with power and power settling with various pundits defining each differently. However for this treatise, I will use the generally accepted terms settling with power and vortex ring state to define the same condition. Power settling will be discussed separately as a separate installation."
But I never got to read that 'separate installation' so never found out exactly what power settling was!
