Helinut - MD 902 / twin torque control
Helinut:
" My recent types EC135/MD902 also have twist grips x 2. Bit more of a handful, although you can always do one at a time. The mechanisms and engine responses are more difficult than single piston engine though. OK for in-flight shutdown, but trying to finesse TR control failures would be interesting."
That is very interesting - yes it is very easy to have very good control in the highly responsive piston - but it still works ok in other light single turbines - so how does it work in the twin/902 - do you manipulate the pair of engines to make the torque change? Very low energy rotor head in the 902 not much energy to borrow from whilst not supplying energy from the engine...
... there was a chap who landed the 902 brilliantly somewhere near London with a T/R fail - great job !! - Was he trained in TR fail?
... and a 902 in Germany not so successful - was he trained?
How would you deal with it with FCL's on the ceiling?
