To answer your quesiton, Robbiee, per the paper, what everyone likes to call LTE is instead "unanticipated yaw", because at no point does the tail rotor demonstrate any ineffectiveness. It could be called "loss of pilot foot control" Per the paper, if the pilot lets significant yaw rates develop it can take quite a bit of time to get it stopped, but assuming full pedal deflection it will stop. If the pilot does everything else necessary, such as maintaining altitude and position, it should stop without the helicopter doing anything else untoward. You really should read the paper.

Edited to add: unanticipated yaw (incorrectly termed "LTE") is not the same as stuck pedal is not the same as tail rotor failure.
Hmm, this sounds like the whole SWP thing all over again. You guys just don't like how the FAA names things.


By the way, if you understand what causes LTE, then you should be anticipating it. Therefore, the only "unanticipated" yaw should be from stuck pedal, loss of tailrotor thrust, or engine failure.
