Helinut Sure.... Testing 'loss-of-yaw-control' speed might be a good idea and it might be the case that that is what has happened here and sure you might well do that - but it is unlikely you'd
deliberately go to the point of a full rotation (as soon as it looked like getting past 90degrees you might reduce the torque - no? Pick up a bit more speed - that sort of thing) - it appears more like -
as you say "pilot is beyond his previous experience and being subject to some very disorienting physical effects." - and he was self teaching by neccessity - nearly got it.
Nobody is criticising the pilot in the negative sense - poor fellow - good effort - very sad.
You
can train for this if you think the maths justifies it.
Was he trained to perform landing in the event of TR FAIL?
It's not such a mystery to teach - a competant handling pilot can make a simulation as realistic as you like in a real machine (with the exception of GoG issues in the event of loss of TR GBox)
That's one reason for the uncomfortable feelings in flying a machine without engine control on the lever.
FCL's on the

'on/off' FCL's
(eg B3Plus)
- not good.... for a pilot...
