It's funny that most of you are talking about the same thing, but have different vernacular!
In the US FAA Land Settling With Power (SWP) is what we used to demonstrate, and is the same as Vortex Ring State (VRS) we demonstrated in Canada... Power Settling would be the same in both jurisdictions...
The requirements to enter SWP/VRS as per the Transport Canada textbook is speed less than ETL, some power applied, and a rate of descent greater than 300 feet per minute. It doesn't take much. This looks like that, but obviously that will have to be sorted by the experts.
Funnily enough, on any PPC in Canada you usually have to talk about 3 things in some detail, those being Vortex Ring State, Loss of Tail Rotor Effectiveness, and lastly Power Settling. In the 20 years I've had PPC's I've had to talk through all 3 every time...
