LTE is most noticeable when heading control is not maintained, and a yaw rate develops that the aircraft pedal margin can not stop. The left cross wind is interesting in the fact that it can offload the tail rotor, but in doing so, also reduces the amount of cross wind required to develop a VRS condition(40-75% of induced flew velocity) less TR thrust means less xwind needed. Once the yaw develops, it continues into the weathercock region, and a snowball effect occurs. With a right xwind a right yaw puts the nose into the winds. Beeping up the rotor, staying ontop of yaw rates, and making pedal turns to the left(power pedal) will keep you well ahead. Another interesting tidbit, in a 206 if a right yaw occurs, the aircraft will descend, left yaw results in a climb, all without touching the collective, this requires up collective when a right yaw occurs, which will again aggrevate the situation.
