Great demonstration. Discussion of muscle memory concerning the collective and holding the cyclic aft and right was also helpful.
Worked for a company in Canada , We did 350/355 12 year overhauls was a Eurocopter authorized Service shop, I use to see are company pilot do these all the time with the bush pilots when they picked up the Machines for a Final Delivery. They mentioned in this video some people don't like to do auto rotations for the machine sake etc, Never seen any mishaps over a 6 year period I worked there, As mentioned a qualified pilot/instructor can do this without any issue to safety etc
that's good to hear. I want to learn helicopters after I finish my commercial multi.
Audio needs more editing in terms of volume. Other than that, Great video

*_Awesome autorotation!!!_*
Very good... Excellent training... Thanks for posting...! Gordon
i knew about autorotation but i thought of it as desperate measure to minimise the fall, i never thought you could manage a soft landing like that just with the rotor momentum that's cool
Been there. My Bell 206 Jetranger (G-KLEE) equipped with tall skids, flamed out at 1500 feet
That last auto was awesome!!
agreed
That is an awesome skill, I am happy it is mandatory to learn it! It is good that the aircraft was designed to allow such a maneuver. That is why I love helicopters, unfortunately my color vision prevents me from ever flying one. I could learn as I love operating machinery and helicopters are my passion!
Nice...
My company has a Jet ranger engine failed had to auto rotate hit the ground hard back injury's. I have wondered if because pilots don't practice full touchdown auto's when they have to do it for real that last part of the landing could end up injury due to lack of training.
Very true
Analysis, instead of analyzation, thanks for the video
pretty anal about grammar are we?
👏👏👏👍👍👍
If the engine fails, and an autorotation landing needs to be performed, why not pull the collective all the way up to full pitch of the blades immediately and flare with the cyclic near the ground?...thanks
+Gary Vale You probably already know the answer, given the time :) But nevertheless: safe autorotation landing needs maintaining the rotor RPM in certain range (given by the pilot operation handbook). This is done by collective pitch control (pulling it up results in less RPM as it increases the load, on the other hand lowering it results in more RPM). Applying full up collective can lead to dangerously low RPM and loss of control. Besides, if your thought was that full up collective will just maintain a slow approach to the ground, well you actually want to have some speed (both vertical and horizontal) - that's where you have stored the kinetic energy that you can exchange for rotor RPM during the final touchdown. Think about wind gusts and things like this, that can complicate the landing.
+Gary Vale because doing so you would "stop" the blades from turning and fall as a rock... you increase your pitch angle only at the end of the flare when you can afford to loose the little amount of energy left (rotor's) to make a soft touch down.. speed is ur main energy source, u can get speed by losing height and you stop the descent by slowing down with the flare (near to the ground, otherwise you'll end up in the "dead man's curve")..
thank you sir for the knowledgeable answer....
If your first action on a power loss in the cruise was to pull collective, you'll stall the main rotor. At approx 75%, Rotor RPM, you can't recover it, without an engine. (No particular helicopter, just a mean average)
In the cruise you must dump collective (reduced drag)...flare (cones blades and aids in restoring main rotor rpm)... Set you speed(with decent) get main rotor RPM in the green and pick your landing site into wind.
This is just the basics..... There is so much more you need to do and consider to get back to mother earth successfuly.
+Gary Vale That will cause the Rotor RPM to drop
Good vidéo thank's
and EC 120 ;)
there is no way this is autorotation..his engine is going fine, just at lower revs most likely
I was in the helicopter. engine at idle. No torque occurring. Freewheeling unit disengaged.
