I did my training in the u.s. and could not get the cfi to demonstrate a touchdown auto. since then i have autorotated many different types hundreds of times onto the ground. in all types exept the r22 autos are just another manouvre and are easier to do than a precision approach in some machines. the robbie is a problem though as each auto is different even down to the fuel burn between attempts,or a little fast or a little slow, too much flare, too little flare, a massive ammount of variables. they take a bit of practice to nail and require constant practice to maintain a reasonable competency level. the fact is in a real life situation if you can maintain speed till flare height and do a reasonable flare to slow down you and your pax should walk away unscathed, after all that is the only reason to do an auto.we also dont have the good fortune to always have an airport under us. what if you are over the forest or the sea or rough terrain. helicopter engines are reliable to the point that most auto training is a waste of time.in the case of the r22 the instructor is doing most of the work and is on the controls, if he isn't he is a brave man. more robbies are written off during auto training at schools than any other accident type. wire strikes kill more pilots than any other problem yet we don't string wires across the runway and practice missing them. fuel starvation is another problem but we don't practice till the light comes on and try to make it home.go and get an endorsement in a proper helicopter and the instructor would be only too happy to do an auto i'm sure

your too high,your too low, your too fast your too slow
