Yes, this brings it in line with the R44 ammendment that switches the governor on whilst you are running at low revs.
You can shake a stick at the number of times that Robbo pilots have seen the RPM creep up to 80% during the warm up period, often with trainees but sometimes through experienced inattention.
When it hits 80% in kicks the governor and you get your 104 or whatever on your machine. Big surprise for the trainee, big surprise for the experienced guy on a slippery surface.
I foresee a rollover with this procedure. Personally I still keep the governor off until I want it on, that is when the frictions are off and I am ready to fly. What to do when you are training a guy with a procedure different from the POH? They will have a good question as to why you are non-standard.
I'd like to hear from Robinson flight ops why they want it this way. It seems counter-intuitive.
