Robinson R-22 Autorotations Online Ground School. Hello. I am Kenny Keller, the creator of the Helicopter Online Ground School and author the Amazon best seller, "Helicopter Check-Ride". These videos are courtesy of our new operations manager, Brian Rutledge and the owners and instructors at Odyssey Aeronautics. Stick around to the end of the video to find out about our test flight, where you can go and look at our training and also more about our membership. Hey, this is David Redmond at Odyssey Aeronautics. Doing some more videos for Helicopter Online Ground School. Today we are going to do some stuff on autorotations. Now, the videos we are shooting ate two parts put together. It's going to be both for the new student trying to learn how to do an auto. Also, for a CFI trying to teach, introduce an auto and techniques. Now, before we even get started, a couple of things that we need to go over ... This has to do with all of the flying. In general, especially in autorotations you want to be ... Do stuff very slow and have very small, smooth inputs. You don't want to being moving the thing all over the place, because you are just going to cause RPM's to go everywhere. Also, as a flight instructor you have to choose your words carefully. You don't want to be in the auto and go, "Recovery." Or go, "Well, roll on." The student is going to panic and roll the throttle on. Always choose your words that make the student feel relaxed and do slow inputs. For example, when I'm ready to remarry the needles I don't say, "Roll on," or "Power up." I say, "Crack the throttle." Or like, "Ease the RPM's up," or "Gently bring the RPM's up." That way the student does it slower, because that what he or she should do. The first step when I am going out and starting to introduce autorotations the student must understand the correlation between raising and lowering the collective and the attitude of the aircraft. When you are entering an autorotation, we are always going to take and lower the collective. Well, when you do that the nose is going to drop. Now, to keep the nose from dropping, as you are lowering collective you have to be given acyclic. Not we are not trying to give acyclic declined. We are just trying to get acyclic, so that the nose stays level and stays at about that 65 nav/attitude. As you are lowering the collective your giving a little acyclic just to keep the nose from dropping. It's important to understand the relationship between the collective and your attitude. If I'm flying along ... Lets say I'm doing 65 knots. I start to lower collective. I do nothing else. When I start to lower the collective, watch what happens to the attitude of the nose. So, here I am going to start lowering and do you see how the nose drops. Now, if I raise collective, watch what happens. The nose comes back up. I'm doing no cyclic inputs at all.
It's important to understand that the collective will control your attitude as well. Think of it this way, when you raise collective, you're producing more lift. So the nose comes up. When you're lowering, the nose drops. So, when you're going to enter an auto, the reason why you're lowering the collective and aft cyclic, is not because you're trying to keep the nose level. Now, that you and the student understand the correlation between collective and attitude. Now, we are ready to start doing auto entries. Now, I don't actually like to take students out and just go, "Here's doing auto. Three, two, one. Boom. Now, copy me." There's too much going on. They don't understand it. It's too much all at once. So, kind of like I approach any maneuver is I break it into it's parts and I slowly build the student up to where I want them to eventually be. Step one, is I do what I call a slow auto entry. Now, when you are flying along ... Now, you are under powered flight. If you just start lowering the collective, the nose will start to come down a little. So, you have to go a little acyclic. Then, if you just keep 65 knots with acyclic and you start lowering collective a little more, and little more and little more, your engine is going to be working less and less and less. Now, if you just slowly keep lowering the collective, eventually you are going to be in an autorotation. That's basically what I am doing is just doing a nice, slow entry. I'll be flying along and I'll say, "Keep 65 knots." Then, I will start lowering collective and I will watch the manifold pressure going down, down, down. Now, I am familiar with my ship.

These videos help so much! And make it easier going into each flying lesson!
Glad you like them!
I'm just starting to learn autos, thanks for the great video Dave!!
Your welcome and thank you!
I like the slow breakdown, and details. :)
+RainbowSixThree Enlightened Thank you for commenting!
Guys do a great job keep up the good work always interesting I learn something every time I watch it
Thank you James
That's a great tip for teaching...thank you!
Thank you Wade!
So...you won't stall the engine at 10 inches?
Great Video...
+S Colbert Thank you very much!
If you have earphones you have to have both in to hear parts of this. Otherwise great lesson
Thanks for commenting!
How many seconds before low rotor rpm/recovery do you have before lowering collective ?
It needs to be lowered immediately!
