Zero Speed Autorotation Practice in the Cabri G2 Helicopter

- I passed my PPL checkride a little over a week ago and just started my commercial training. This was my second zero speed autorotation during my first commercial lesson. I must have not inserted the GoPro audio adapter fully as there was no cockpit audio so I added a voice over commentary.

I love helicopter training.
These recovery maneuvers are awesome.
Really surprised at the slow descent rate in the autorotation. It was almost boring. No high anxiety in that maneuver, which is exactly what you want. I like this helicopter!
It may be a different story if we were the pilot flying ... 🤔
It started out a 3.000´ RoD after initiating the AR with setting at 2.000´ RoD at 70 it’s IAS most of the way down.
I haven’t sat in on a zero speed auto, but my instructor has demonstrated regular and turning autorotations to me, and you definitely feel that you’re falling, but it’s not like zero-g or a roller coaster, just kind of feeling a little lighter until the aircraft settles into the glide. Requires a lot of quick reaction and constant gauge scanning, though, which is super stressful to me as a new student.
@@joshua.merrill I'm a new student as well, I think I have about 16 hours and only practiced autos a few times. It's definitely tough to keep track of everything while you're doing autos, especially when you get closer to the ground and it looks like you're coming down too fast, I puckered up pretty hard the first time I did it🤣. For me it's always the rotor rpm's that get away from me the second I take my eyes off the tachometer, I have a tendency to let those rpm's get a little too high.
@jcoghill2 I think the smoothness of the camera has a lot to do with it. The few times I've done autos it definitely seems like the ground is coming at you a little too quick. I trust my instructor so it's not super stressful or anything, but it's a lot different when you're in the seat. Actually it's a lot more fun than doing a normal (powered) approach, I might start asking my instructor if we can do autos every time we come in for a landing to get more practice in and have a little fun while we're at it, kill 2 birds with one stone 🤣
I’m not familiar with this type of helicopter but according to my experience, when starting an autorotation from a hover, your first priority is to bring back up the Rotor RPM (like in any case) by immediately lowering the collective and ‘sinking’ down without increasing forward speed until RRPM has recovered enough and only then pushing the cyclic to increase airspeed. Pushing the cyclic forward creates negative (or at least less than 1) G which in turn drops the RRPM even more contrary to the aim of gaining back RRPM. So, first bring up the rotor to the desired RRPM and only afterwards bring up the helicopter to its desired airspeed.
Having written all this, it depends on many factors and therefore I may be mistaken with this specific video.

As mentioned in the video, the first thing I did was lower the collective. After that, getting your speed up is important for the flare. Being that we are starting at a hover, we need to push foreword early on to give our speed time to build up. The main reason for pushing so far forward is so you can recover your airspeed from a 500' AGL hover. A 500' hover is considered the minimum safe OGE hover in the height-velocity diagram of the helicopters I fly. We practiced this from 1000' AGL for safety. If you watch the gauges, I get to an adequate flare speed having lost more than 400'. If I were doing this at 500' AGL I would immediately be transitioning into the flare once I reached autorotation speed. That is the reason for the early push forward. In my opinion, a 500' AGL hover does not leave much margin if you have to do an auto.
@@MichaelHeliGuy Thanks.
That looks like a sweet little machine. If the stops are set correctly you should be able to shut her down, bottom the collective and do a vertical descent until near the ground....then forward a hair for a motionless stop. Les humble showed me on my commercial check in hughes 269b.
Excellent.
The one thing that I find really annoying about that is the instructors constant inputs to the stick. If it's slightly off, does it matter. You'll notice it soon enough.
He's probably trying to show you that you need to act on what the aircraft doing sooner and yes that can be annoying. Instructors want to see you make corrections before they become an issue. This way it shows them you are mentally ahead of the aircraft.
In a low altitude zero speed auto it’s important to get up to flare speed quickly. My instructor will ofter give me physical cues like pushing on the cyclic. This maneuver is not required, but I felt it was good to experience it. I have many videos with this same instructor where his hands never leave his lap. Slowing down in an auto is something I’ve done in the past so he’s making sure I keep my speed where it should be. Because of his experience, he will often sense a change in speed before the airspeed indicator registers it. I’ve seen him do this numerous times.
Like a boss!
sangat keren...

What mount you’re using for the camera?
A GoPro shoe is stuck to the back of a 6” plastic clipboard. The clipboard is clipped to the POH in the pouch on the back wall.
That's les hemble of south Carolina helicopters.
Nope. That’s me in MD.
@@OnyxIGPIII sorry, I only meant the guy who showed me the vertical descent trick many years ago in the hughes. He's long gone by now.
If this guy is a COM pilot, GET the HELL off the CONTROLS already. Holy shit, amazing how many CFI's are on the controls.
If you read the blurb below the video, he’s only just got his PPL (passed his check ride a week ago) and is now starting commercial training, so not a whole lot of experience.
Sadly you are clueless moron i.
That’s a 9000 hour CFI and that’s not on the controls. That’s a THUMB nudging the controls forward as the student does his first couple zero speed autos.
Amazing how many arm chair quarter backs are clueless about what they are quarterbacking.
He even verbally stated it was his first commercial lesson.
@@OnyxIGPIII Ah, how precious...I'm a 13,000 hr actual professional pilot
Hahahahaha. Sure you are.
A professional wouldn’t have even commented about a video of flight training being performed during a first time maneuver.
Of the 6 helicopter instructors I've had, this guy is by far the best. This was my very first zero speed autorotation. At the time of this lesson, I had about 78 hours. The control nudging was to remind me to not pull back. Doing an auto is very different than, for example, a normal approach. In a normal approach, I slow down gradually by pulling back. In an auto, I need to keep my speed up until the flare. The instructor nudging the controls forward is a reminder this is not a normal approach so stop pulling back on the cyclic. I have a number of other videos posted where you can see my instructor's hands in his lap during the entire auto. In those cases, I kept my airspeed up until the flare.
