Yes and apologies to other types referred to but the Woodward Single Channel (FADEC) is pretty similar to PWC PT6 where used and PWC 200 Series.
So the similarities to 139 will exist amongst others like AW109, EC135P models, MD902 and Bell 427 and 429.
The mechanical connection does vary between overhead levers and twist grips and is supplied by the framers. Naturally there are some slight differences in the way things are implemented.
If so would it have been possible to control power and RPM by using them given that the collective was essentially stuck at a fixed pitch due to the carbon fibre control rod being reduced to a liquorice stick.
More than likely but with the overhead controls you may be busy and it would need a 3rd arm possibly to do it if the ECL trims were INOP if you were SP.
Not aware of what is/was trained for in this instance.
