John Eacott, that is a great Ops manual explanation. A couple of points from a different perspective:
It does not distinguished LTE from loss of tail rotor thrust in the opening explanation.
Para D3.3 does not explain the symptoms "prior" to LTE, rather it details symptoms of developed LTE.
Para D3.4 (c) and (d) say the same thing. For para (e), this recovery technique came in for critisim afetr an Australian Army B206 suffered from LTE in a fifty odd foot hover and the (low time) pilot correctly carried out checklist actions: Lower collective - if insuffcient height remains to enable the collective to be lowered: conduct autorotation. Further investigation of the accident concluded that the checklist could be ammended to reflect a revised approach to an LTE situation which was to maintain collective (where low altitude prevented lowering it) and use cyclic to fly out of the spin with forward and out of turn cyclic application. Obviously, such action requires the pilot to be full conversant with the difference between LTE and loss of tail rotor thrust - hence my first point.
As an aside, and quite disappointingly, the fact that the pilot correctly carried out the checklist actions in the above accident did not seem to help him fight critisim of his actions by more senior pilots.
Para D3.5 (b) (probably unitentionally) implies a limitation on your aerial filming operations to be conducted above translational lift regardless of helicopter type or conditions. This may indeed be prudent in B206 Ops with low time pilots, but I think it is not appropriate in AS350 or BK117 ops.
