The Frenchman is right: Sometimes you have to stab in *FULL* pedal RIGHT NOW (and hold it) to stop the UY.  If the UY occurs on approach, pushing full pedal may very well cause an overtorque or droop.  Meh.  Do what you gotta do to keep it from going 'round and/or crashing.  


There are a lot of things that go into an "LTE" event.  But the key is to catch it early - don't let a yaw rate even start to build up. Catch it!  Be aware if you're landing with a tail wind, especially if you've already got a bunch of power pedal applied. Downwind approaches are not advisable, of course, but sometimes they're unavoidable. So you better know how to perform one. That's what they pay you for.


Oh, and for you young, book-smart pilots?  In 40 years of flying helicopters, I have never ever ever ever ever ever gotten UY (or "LTE") by approaching with the wind off the left in an American (or German) helicopter.  I know a lot of you smart guys will look at those three CHARTS OF DOOM! and go, "See?  Left crosswinds are bad, mmkay?"  They're not.  Trust me, they're not.  Be aware, stay awake, and be ready to counter and stop *any* UY before it becomes a problem.
