How does the Yaw Load Compensator work

Many of the AS350/AS355 models of helicopter have a yaw load compensator. This device is often misunderstood in its make up and operation.

I train pilots in the B3e and your videos are very helpful. Great content keep up the good work!!

Thank you for making these excellent videos!

I like the Hughes 369 load spring to compensate for T/R strap forces. . . Less monkey motion

Great tutorial but I feel like I might have missed something here. I'm wondering why you made no mention of the procedure with regards "Loss of Tail Rotor Control". The RFM states that once 70 kts IAS is attained to activate the [ACCU TST] button, which then depressurises the "Load Compensator". In other words, the load compensator - once depressurised - gives you 5 secs to gain a more neutral position of the pedals, should they be greatly offset. After 5 secs the [ACCU TST] should be reset to off. 
In my mind, I was under the impression that this was the main purpose of the Load Compensator, but of course I could be completely wrong. I'm keen to gain more understanding, so again, thank you for sharing and thanks for hearing me out. I would be more than interested to hear your comments on this. Cheers.

Does the yaw load compensator have a limited time of utility after the failure of the hydraulic system? If so, what is the time limit? Or is it a limited by how much pedal movement you are making? Say, you're in cruise flight at a power and speed configuration which requires little pedal articulation. Must you land " as soon as practicable " or can you continue until an ideal maintenance location is reached? I'm assuming in this question that the main rotor hydraulics are still operational... You're my new favorite channel. Thanks for making these informative videos!

Thanks again for these videos. Can you explain why we are instructed to bleed off the Yaw load compensator after each flight?

Would consider making a video on the Astar and LTE ?

Absolutely the worst generalised waffle I have ever seen.... nobody gets it. From the crap you have blurted you are saying the hyd fluid re re=routes back to the servo....or the charge in accumulator actson the rod downstream... zero about the over centre arrangement.
