And as it happens, in those three situations you are putting the aircraft at the height and speed of the scenario you are simulating - your Vuichard demo had the height but not the speed so please tell me what you learned from it.
Well, given that the most likely scenario for getting into VRS on approach when you think your airspeed is sufficient, is because you're in a tailwind, doing this simulation with a good amount of forward speed was correct for that type of situation.
Anyway, I learned what it would look like to perform that maneuver at low altitude with forward motion, intead of the usual OGE hover at 2,000' agl.
Sorry if this offends your sensibilities, pal, but I haven't done anything new in a helicopter in a very long time, so it was a nice break in the monotony.
