PLEASE READ FOLKS: My hat is off to Mr. Vuichard. Sir, I owe my life to this technique. True story. I am a retired US Military Pilot (US Army helicopter pilot with over 37 years of flying experience, accident and incident free all of these years, I'm retired now). When I retired I started flying EMS helicopters.
I responded to a scene flight at 2:00 am in the morning, zero moon illumination, and overcast skies. I had my ANVIS 9 NVG's thank goodness. My landing zone was extremely tight and I made 3 attempts to land with no luck so my last option was to land with a tailwind (not the best decision), I should have landed at another location and had an ambulance take my medical crewmembers to the scene, but I didn't.
On final approach at approximately 400 to 500,' I IMMEDIATELY started to settle in my downwash (Vortex Ring State, VRS). I knew right away what was happening, not my first time in VRS. The trees were 150' (tall pines), if I had attempted to recover the old way, by lowering collective (altitude permitting) and flying out of the VRS I would have smacked the trees (98% sure that would have been the end result).
Sir, I performed the "Vuichard Recovery Technique" I learned 6 months earlier and BAM!!!!! I "immediately" stopped my sink rate in
Mich B Glad you got out alive Mr.B☺ Great comment!
Love this comment - top work sir
Awesome stuff. Thanks for your service.
Awesome testimony! Everyone needs to learn this Technique
Congratulations on your amazing achievement! This looks like a challenging situation to get out of. This visual helps in the understanding of the laws of The Vortex Ring State. I am happy you were able to save yourself in that situation.
This very clever presentation should be shown in all helicopter flying schools and annual recurent trainings everywhere. So clear ! It will save helicopters and lives. Merci !
You are so correct, read my comments above. I am going to call Fort Rucker and talk to the Army Senior Standardization Pilot at the US Army helicopter school and ask is he has seen this video, if NOT I will send him the link.
Tail curl
I've seen quite a few illustrations of VRS in my time, this has to be the best by a very long way.
Thank you sir.
Great video and very well done. We have been using this technique for over 25 plus years in the Canadian Helicopter industry. It is extremely effective for longline operations. The use of spray booms gives the perfect visual effect. Two thumbs up!
KMAXdawg ...guess Canadians can keep secrets ha haha
I’m not sure who gave this a thumbs down but I hope they never fly a helicopter with passengers. In every walk of life you will find knobheads I suppose. Great video. Great visuals. Life saving techniques demonstrated. Thank you.
Probably the annoying dramatic music and the excessively long intro and outro?
Thank you for this beautiful video, but most of external load pilots knew and used this recovery technic before you named it Vuichard, as vortex are part of our daily job.. Cyclic foward (or into the main wind) and pich lowered is still a good technic depending of the vortex conditions, quality of your blades, rotor efficiency, trajectory/path, hight, (cross)wind(s), landshape and type of obstacles you got around you. One technic, does NOT replace the other, they are just complementary and combinable.
Excellent demonstration that will save lives. Deserves a safety award.
Great idea for visualisation of air flow. . . and concept of new, more swift exit route to recovery = should get award. Thanks all.
This should be mandatory viewing. Good job, and thank you.
GENIOOOOOOOOOOOO !!!!!! GRACIAS POR ESTE VIDEO. I ALSO TAKE OFF MY HAT TO MR.VUIVHARD BECAUSE OF HIS BRILLIANT TECHNIQUE, BUT WHAT IMPRESSED ME MOST, WAS HIS WAY OF SHOWING IT. CONGRATULATIONS AND I REITERATE MY GRATITUDE
Thank you Claude for all your work and engagement for safety in the helicopter business. Absolutely brilliant and clear message for all pilots.
Awesome! What a greate idea to use a smoke generator to visualize vortex ring, with a live flying helicopter!
I would say Ag booms and water through the nozzles.
Well done my man. Clever. Realistic. Teachable. Must become standard recovery maneuver .
Brilliant Demo!
I'm not a pilot but have a deep love of helicopters. Have spent many hours in a sim thanks to a good friend and successfully did a number of autorotation landings and a 360 degree pirouette with nose pointing at a fixed object. Simple for you pilots but a bit much for a total rookie. I just want to add my compliments about this amazing video. Seeing the phenomena actually happen and how to recover gave me goosebumps. Awesome video and no doubt it will save lives. Seeing is so much more effective in teaching than just words or drawings. Bravo!
E Smith I can recommend RC helicopters. Basically even harder than real ones (in some ways) but much cheaper and safe! Very rewarding when you progress with RC. Oh, also, inverted flight!
I am a helicopter engineer, not a Pilot, however I use a simulator and enjoy flying the simulator. I have practised this procedure upon discovering it recently, also spend time really understanding everything, getting out of the dirty air as quickly and safely as possible.
Wow, that's the best visualization of VRS I've ever seen!
Really cool way to visualize it
What a phenomenal demonstration!! Thank you, sir!
What amazes me is how quickly the vortex is destroyed, the helicopter only needs to move sideways by half the rotor diameter and the vortex just breaks up. I had visualised that it needed to move sideways by a whole diameter but it appears that you don't. Excellent and very informative.
Thank you for an excellent presentation. This really helps visualize what happens.
Awesome demonstration. The UH-1 with counter-clockwise rotor, you must use right cyclic. Thanks for this video!
Incredible insight into vortex ring state. Thank you
This is an amazing video showing the Vortex Ring State. It was visually captivating, and showed the air and how it behaved around the helicopter. This method was en genius. Thank you for sharing your knowledge!
Феноменально!
Пилотам надо дать соответствующую премию. Операторам съёмки тоже.
В первые вижу визуализацию вихревого кольца несущего винта выполненного на реальном вертолёте!!!
Спасибо
Большое спасибо за добрую обратную связь!
Very good explanation
What an amazing demonstration. Great job
Wow wow wow, what a fantastic detailed demonstration, thanks for doing this 👍🏻♥️
Awsome video! Thanks so much for visualizing this manouveaour!!
Absolutely stunning!
Thank you Shaun
One day I will fall into a vortex ring and I will escape it with the technique learnt from this video, for that I will be eternally grateful.
Excellent training video, thank you so much for creating.
Very clever, well done to show everyone! I hope this video reach very far!
Bravo! To all involved in the creation of this video.
Great video and lesson for all the aviators out there..thanks 🍀
It's pretty cool seeing it with the spray set up.
Awesom! more clear visual understanding. Thanks Vuichard

Absolutely awesome teaching video!!!! Many thanks.
Amazing technique
WOW! Nothing like a visual!
Absolutely amazing presentation!! 👏🏻👏🏻👏🏻👍🏻👍🏻👍🏻
Thank you, this is an impressive demonstration ! I am sorry but, does it happen only when there are "walls" (as in canyon, or montains) allowing the air flow to make the ring ?
MY HAT IS OFF TO YOU GUYS GREAT WORK !!!!!!!
Great tool for helicopter pilots. Let's also discuss when it is not the right tool for recovery from VRS.
Obstacles on the side you would translate toward for this recovery would preclude its use. Also, if you're already moving forward, such as during a normal approach, a forward recovery should still make sense. Also, if there's any confusion during the event whether the descent & vibrations are from VRS or overpitching, the traditional recovery should be used, because it solves both.
So, Vuichard Recovery is a great technique--the best in certain circumstances--but not an absolute replacement for the traditional method. CFIs should teach both, and especially should teach when to use each.
that was the most beautiful thing i ever seen
Very well explained and shown.
great video, great visuals
would be really helpful to show more from inside the cab to "see what it feels like" as I imagine there is specific feedback from the heli which should be taught to be recognized
Absolutely brilliant !
Great job 👏
This might be the most important life pro tip video on TH-cam.
❤thank you for sharing 🙏
I fly drones and have experienced the VRS phenomenon! Great visual !!!
Excellent presentation!
love this alouette ,mean lama sa 315 n the alouette 2 n 3
Wow, to actually see the airflow going the wrong way through the rotors is really enlightening. And terrifying. I'm a fixed wing pilot. But I'm curious as to whether you can get in the stall far enough to where you wouldn't even be able to command a roll to execute this. I'm a fixed wing pilot, but I find this interesting.
Wahou fabuleux très instructif et ces image expetionnel on comprend à merveille.
Excellent 👍👍👍
Very interesting, impressive & so good to understand what happens in this situation/maneuver. Also for me as a huge 🚁-Fan with only R/C HELI experience & without a real pilot-license ;]
Cool video 👍🏼‼️
Wow! Great job.
wow just wow this is excellent where you got the idea and then the execution of the whole plan this is awesome you explain something to me in a way that no one else can thank you thank you very much
Wonder why this wasnt thought of earlier. Why did they use either forward or backward opposed to sideways?
this is safer...no doubt. The other way is much more fun though! Love diving out of it to get that airspeed, kind of a rush.
Great idea .... One thing I don't understand the Lama is a CCw rotor sys( looks like I am not rated) and should escape to the right by description note "2" but instead in the videos it escapes to the left??!
Someone could explain where IAm wrong?
amazing.....
Wow, great video and ama Inc technique 👍
Now this is Cool !
A Real life Monster, Will Kill & Its, " GOT YOU "
Now I know what to do.
Thnx.

Great video!!.
Excellent demonstration. What technique would you recommend if the aircraft was rotating uncontrollably and descending with an armful of collective? i.e. Settling with power and spinning. (Personal experience - (;>0))
Dear John
The points listed below primarily to avoid uncontrolled turns:
Hover flight or very slow speed flight with helicopters.
Wherever possible, rotation around the vertical (yaw) axis of the fuselage in hover flight should always take place in the direction of the main rotor rotation (power pedal). This requires more power, but can readily be stopped again without the need for additional power.
If an unintended rotation in the opposite direction to that of the rotor should occur due to cross or tail wind, or as a result of a sudden increase in the collective pitch, the following action should be taken immediately: The power pedal of the tail rotor control should be applied, if necessary to its maximum extent (mechanical stop), and held in this position until the rotation stops.
When a helicopter is being operated at the limit of its performance capability, for example in the mountains, it is important to operate the power pedal at an early stage, especially on approach or when rapidly increasing collective pitch, in order to ensure that no directional changes in direction around the vertical (yaw) axis can occur. This action prevents an unintended rotation opposite to the direction of the rotor rotation, which can only be stopped by applying additional power and usually results in a decrease in the main rotor RPM, since in certain circumstances the required additional power may no longer be available. A decrease in the main rotor RPM leads to a corresponding decrease in the tail rotor RPM, which may, in certain circumstances, result in a complete loss of tail rotor efficiency.
Hover and very slow speed flights out of ground effect should be carried out with sufficient reserve power and only by pilots who have been trained for this kind of operation (CPL level) and have the necessary practical experience.
Best regards
Claude Vuichard
My one and only episode occurred during training in mountain flying techniques in the Rocky Mountains many years ago in Alberta. I took control from the other pilot, dumped some collective, opposite pedal, forward cyclic, and were out of the situation in seconds. (We were tucked up tight to a mountain, so had altitude to play with if we didn't tumble down the mountain side first... (;>0))
What an excellent video. I understand now. I fly model quadcopters and would I be correct that there will be two vortexs per propeller then?
Increase collective? To max power?explain.
Increasing collective would cause more of a stall right?
It provides max authority to the tail rotor.
thank you!!!
Question1
Why ccw right, cw left
Question 2
Why bank 15-20
Nice job girlie ✌
Are they using the tail rotor to provide thrust out of the ring state? Like would this work with a coaxial or tandem rotor?
Hello there , I have a question. Military pilots have to undergo confined area approaches in the field, where the rate of decent is arrested at 500-400 feet and then at the end u come up on power and settle down the aircraft. Could you pls highlight another technique for this. Pilots arrest the rate of decent till 4-500 and speed within ETL TILL THE VERY END . If you have something to add to it, I’d be very happy to take note of it.
Thanks
Hard to believe that with helicopters in service for so long it took until 2017 for someone to work this out.
Is it "Robinson" or "Robison" at 0:33 you have "Robison" in that text and I would like to know what the correct name is. Thank you.
Hi Ursus, It should be called Robinson, a vexatious mistake..
So basically vortex state is sliding/falling off your own lift?
In the Vortex Ring State all energy is used to re-accelerate the induced rotor flow in a closed physical circuit. As a result, the helicopter is trapped in a bubble that becomes heavier and heavier than the surrounding air and the bubble sinks because of the gravitation. Depending on the rotor disk load the captured helicopter sinks with a rate of descend between 3500>6000ft/min.
Don't do this in a Robinson, it may shake the tail off. Lots of helicopters falling out of the sky with missing tails lately.
What is power pedal ?
In a Lama it’s the right pedal
As dangerous as this is it looks very cool
heya, that music is from one finger death punch :o

#1 advise: avoid VRS to start with.
Why a sideways escape as opposed to forward or aft?
You're pulling max power and using your tail rotor to push you out of the vortex. The usual taught way is you lower collective and nose forward to get out, here you pull power while applying power peddle and cyclic opposite to have your tail rotor thrust move you sideways into clean air. Works much faster.
Less loss of altitude=less chance running into obstacles or into the ground.
Less forward or aft distance to cover=less chance running into obstacles.
Aft is bad because you can't see what's behind you.
Makes sense, thanks!
We use the tail rotor thrust tu pull the helicopter out of the VRS. Going forward does`t work in tail wind conditions, you will follow your downwash until the accident place.
The pilot is from God !!!!!!
к сожалению мало кто умеет читать и понимать то ,что видит. Поэтому вместо лопастей должен быть принципиально новый вид преобразования воздушных потоков
Должен кому, если не секрет?
@@ShadeAKAhayate Должен ни кому а самому себе в понимании того в чем нуждается и какими способами и методами он может достичь цели
@@АлександрБогайчук Ну так и придумали вертолеты для этого. Их недостаток в виде ВК -- продолжение достоинств. Других вариантов ЛА такого типа пока нет, а схожий по принципу полета конвертоплан еще и кратно более опасен.
let's practice over some steep terrain just in case something goes extremely wrong like engine failure...
2:13
Is anyone else here to learn how to not crash a chicane?
I guess this is what caught colin McRae out for flying like a prick
TO bad they branded the video, kinda ruins the shots and focus

This is SOOOO important, save lives, so stop that shitty music and let us hear what happens. Let us be WITH you, fly WITH you, share the REAL experiance. This video feels like a commercial, a happy flight.
Why always that music ? Because everyone does it ? In this case the music ruines the message.
ca vol mal un helico ... 4 pales sont plus stable
It is quite unlikely you would recover from fully established vortex ring state, as you lose control of the entire wing surface, therefore any cyclic or collective input has no effect. VRS comes from extremely poor handling and spacial awareness and 'incipient vortex ring' develops first. This is evident from increasing vibration and rate of descent. The best practice to exit incipient VRS is to lower the collective and nose forward to get the air flow over the disc again. Once above 30 kts ish, apply power and fly away. Doesnt look like this demonstration was remotely approaching VRS or even incipient VRS, which when developed will give a rate of descent of up to 8000' per minute. To get into VRS you need low air speed, typically less than 30 kts, high rod and then pwr applied. So much nonsense on you tube.
