Hi guys,

CJ-E: First I think you are mixing up something with your factory course-15 ft-auto and so. I also got the factory course and I got it from the man who did all the test flying for the R-22. In no way he endorses or recommends a 15 ft hover for primary training! Period.
On more advanced training you might want to practise this for any possible mission, but for regular hover you want to stay between 3-5 ft (the man says...)
If you did the factory safety course you probably saw the video with the R-44 HV-diagram flights. The R-44 was at less than 50 kts, about 50ft, cut throttle, 2 sec reaction delay - he was sitting on the belly, the gear spread out horizontal! The R-44 was single occupant. Forget a no-damage, 15ft no- indicated airspeed auto to a hard surface in a R-22 - I donīt see it. I train people in at least 2000ft DA - in your place even less so.

CaptainEagle:
Recommedation - keep it boring for a long while. Until you have lots and lots of practise autos, quickstops etc.
Maybe it is because I was pretty dumb at your age, but on the other hand I just got it confirmed again:
I gave a 22 year old 150 hr CPLH a crashcourse for tunaboat ops. I thought I got through to him about showing off. For finacial reasons he would not go on a boat with me to do approaches and landings, but would go with a different pilot doing radio tests(so he safed about 4 hrs of training expenses...).
Turns out that this guy is a real hillbilly-show-idiot.
After 50+ successful hours flying my student got cookie and tried copying the hillbillies stunts like quickstopping the helicopter onto the deck of the boat - bang! there goes the TR.
He survived to get fired!
Most likely thats where his career stops, as he proofed that he is not mature enough yet...

Coyote: You are absolutely right - this specific maneuver is not for PPLīs. Not even for a regular CPL. I demonstrate (no student practise) this maneuver as a means to show where the limit is in auto flare or quickstop - Cannot pull more back cyclic than Rrpm allows (overspeed) after that you climb and end up high with nothing (rpm and/or speed). Mostly they get the message.

Nulian:
However there is at least one comercial application:

When we started to Ag-spray with a R-22 we where urged not to fly ag until factory checkout (Spray equipment manufacturer) - they where right:

In case of an engine out while spraying at 65 Kts and 3 ft of the crops you have no time nor space to flare off the speed, so immediate reaction was a fairly hard aft pull on the cyclic with collective unchanged, which would baloon the R-22 to about 10-12 ft, where one would get the collective down to maintain Rrpm. Once down to 40 kts (which happens in no time at all!) you flare it so hard that you just see sky strait out front (I learned subsequently to look out the side.........getting old, learning slows down too ) which kills the rest of the speed - tricky thing was not to hang there too long, but leveling the machine before the 10ft altitude where gone and run on level. It was exciting, luckely I never needed it, long live the Lycosaurus!!

Maybe doing film work you may get caught in extreme low level flying, but generally one will have enough to do to keep regular autorotational skills up!

Heliport:

Your line about just.helicopters LOL
There is no way this here gets so bad, ever!
