to Thomas Coupling:
regarding your post on page 3, I don't follow your reasoning for the nose to continue yawing opposite the MR blade rotation in an auto once the engine has been removed from the equation. In an auto, once throttle is reduced, there is an immediate requirement for right pedal (american helo) which would lead me to believe that if the TR had failed, the nose would be yawing in the direction of MR blade rotation (left in american helos). Perhaps you could clarify your post, or correct mine... thanks
