FL has started another thread going "Pilot's death may have been avoided" about the sad BO 105 accident during external loads. The thread includes reference to the recent AAIB report which relates how the TR was impacted by the load during the accident. The report then goes on to talk about "loss of tail rotor effectiveness" and make recommendations that the CAA should publish information about LTE for helo pilots.
This may explain the FODCOM about LTE coming out just now - it is the CAA ticking the box on an AAIB recommendation.
This use of the term LTE adds yet another extreme definition - Is it LTE if you have lost tail rotor thrust (and/or your TR)? Surely loss of TR or TR thrust is a different animal from LTE?
