I did not claim the cruise /climb technique to be a fact, I said I do not agree with
his (more bold) opinion that it was unrecognisable. I also don't claim to know more, but I do recognise the technique. Simple.
My entry to this discussion was spurred by comments like this from ShyTorque:
Presumably you have a lot of experience in flying rotary in icing conditions?
Most rotary pilots only try it the one time.
Just not true!
