Well, the concept of an autorotation is very simple and direct. Flip the Throttle Hold switch, point the nose down a bit (preferably into the wind), apply negative collective (and steer the helicopter around with the cyclic and rudder), then flare with positive collective as you approach the ground.
However, in the "panic of the moment" there are a lot of things that can change. The best way to introduce yourself to autorotations is to do them on a simulator. I practice a few auto's each and every time I am on the simulator. Upright auto's, I can do them pretty well and pretty consistent. It's just like any other aspect of a helicopter flight...practice...practice...practice.
