Good information Kenny. With so many people on the internet pretending to be flight instructors, it's good to see someone who actually knows what they're talking about.
Great video! You do a great job keeping it clear and concise. I had a student get us into LTE just a couple weeks ago trying to terminate to an OGE Hover with a left quartering headwind. He had no idea why the nose started yawing and almost overtorqued trying to stomp left pedal. I sent him here to do some homework. Keep up the good work!
Thanks for the feedback! Please share our site address with students: www.helicopterground.com Also we would love to have you and your students join in on Live Tuesday training. It is free and we have both experienced and student pilots from all over the World that jump in on the live chat. It is a good time in learning.

Good video BUT, the direction of wind affecting the tail rotor by main rotor interaction IS dependant on the direction that the main rotor turns - different for Eurocopter/Airbus vs MD/Bell etc.
Yes spam mouse, but keep in mind that the natural direction of un commanded yaw in LTE incidents is still towards the advancing main rotor blade regardless of the manufacturer specs.
One thing to point out here regarding the recovery technique. The first action needed is missing, the first action during the unanticipated right yaw is to apply left pedal input without any delay and apply other control inputs as described. Without the application of the left pedal, the situation will become worsen. In case of low altitude and restriction for forwarding flight, the only immediate response is to be the full application of the left pedal. The latest FAA rotorcraft handbook tells to apply the left pedal whereas the previous version had this point omitted. Please share your thoughts.
Direction of main rotor rotation will affect the AT pedals. I remember taxiing downwind using 75% left pedal and then 75% right pedal to turn into the wind and it will snap around and you won't have enough left pedal to stop it. It was better letting off the left pedal, turning left into the wind and having plenty of right pedal authority to stop the turn.
It has to be happening in sequence to get into LTE, m/r interference, then t/r vortex ring state,and then weathercock stability. If you get in just one of them it is controllable.
Nice video about LTE. As you use this video for educational purposes I would recommend you show this video again but with the helicopter hovering at a 8-10ft hover. This video is a perfect example of how NOT to hover (so close to the ground) as you are very prone for dynamic roll over. Especially for the more in-experienced pilots this is a poorly chosen demonstration. Heads up for the good initiative of explaining LTE .
Thanks for the input Matti. We hover as a standard 3 to 5 feet. The FAA publication Rotorcraft Flying Handbook recommends lifting the helicopter to two to three feet (page 9-3 Vertical Take Off To Hover). Many helicopter manufacturers recommend three to a five foot hover. I have not read or attended any training since I started in 1997 that recommends 8 to 10 feet hover height. What is your resource that recommends eight to ten feet hover height?
Me: I think flying helicopters would be awesome! YT: Here’s a long list of all the things that can go wrong with just one aspect of flying a helicopter. Me: Never mind.
The Tail Rotor and main rotor is geared and shafted to spin at a set RPM and is fed from the Main Rotor transmission. The only instrument needed to monitor these two is the Main Rotor Tachometer, since they are connected. Grab a free copy of Amazon #1 best seller, "Helicopter Check Ride".

This flaw in the small tail rotor of the 206L models has killed too many people.
Ken Quesenberry Thank you!

Yes this video was produced back in 2016 based on the Helicopter Flying Handbook, before the revised Helicopter Flying Handbook published in 2018.

EXCELENT! best video ever seen explaining LTE and recovery technics.
Wow, thanks!
Sounds like the Army Flight School TH-67 (Bell 206) Handbook to me :-) Still remember, 5 years ago, study study study... well done!
BK117Dude thanks for commenting!
Just by the way:
The BK-117 is a very good Chopper 🚁👍🏼‼️

alqahtanis3oood ...THAT helps break it down even further/better...
Thank you for the feedback!
Excellent video. Very good explanation. Congratulations.
Thank you for your feedback!
If the wind starts blowing and causes yawing...why do dome pilots not correct with opposite input and start spinning?😮
i am LIKE # 1000! \o/ -Congrats!
Thanks for commenting.
How can i get the whole advisory Circular for helicopter 🚁?
Help please

Yep, regular 3-5 foot hover. Great example and demo here, guys.
Doesn't main rotor interference cause a vortex ring state in the tail rotor, because of the turbulent air being blown into it?
That discussed in the video turbulent being blown in ti the tail rotor!
Great video - thanks!
Stefan Smuts thank you!
What's your opinion on those Mosquito helicopters ?? 🤔
We don't have any experience with the Mosquito.
A lot to know and remember in order to be a good competent helicopter pilot.
Exactly! thanks for commenting!

It actually is very safe.
Where is helicopter speed back roter ?

Thanks for commenting!
I bet sprint customers know what it’s like to not have LTE!
Thanks for commenting.
Why not just make the tailrotors more powerfull???? Semms so precarious.
Nature of the beast!
Turn the captions on and this becomes a “loss of Toyota effectiveness”
haha
You'd think coaxial would be more common.

Very, very low justification for landing any helicopter, any time, out of wind.
Thanks for the comment. Landing into the wind is always the best practice.
