anypilot - Well, sorry but there is a thing called Loss of Tail Rotor Effectiveness
Nick Lappos Sikorsky test piot - There really is no such thing as Loss of Tail Rotor Effectiveness, BTW - for a given density altitude, the tail rotor always produces a given maximum amount of thrust and a given maximum effectiveness, it is just that it can be swamped by main rotor torque rises, and by crosswind effects. Generally, only marginal tail rotors experience LTE, and the vast majority of LTE events are experienced by only two types of helicopter. LTE is not a pervasive helicopter problem
anypiot, the history of the term LTE is an invention of Bell to explain to the US Army accidents they were having with the OH -58 and UH-1, they are the two aircraft referred to by Nick Lappos above. The reason for their accident rate was that the tail rotors were not big enough. Terminology is important, LTE is not loss of tail rotor thrust as pointed out by
Robbie. With a few thousand hours in both and 20k total only once in a 206 with a sling load into a mountain
we have all been there or close to it, too
