If you visit Penticton BC. You will find hovering autos from 100 to 150' performed all day long in Bell 206's.Zero forward airspeed, just a vertical hovering auto.
A check or two on the collective on the way down.
Very spooky the first time the IP demonstrates it and then easy peasy- Once those guys show you how! and are sitting alongside in case you muff it
I am definitely not the only guy who went through the CHC mountain flying course so corroboration should be forthcoming...
Racing to get forward airspeed is the last thing I'd want to do in the bush!
