Just back from Bell Training Academy B407 recurrent where I was told that Vne in the B407 is not limited by RBS but rather by maximum allowable forward cyclic input under FAR Part 27 certification standards. As I understand it, Part 27 requires that the helicopter meet the relevant certification standards using less than maximum physical cyclic inputs. With the maximum allowed fwd cyclic, the IAS turns out to be 140 KIAS, which becomes Vne. Presumably RBS occurs somewhere above 140 KIAS (for the DA's at which 140 KIAS Vne applies). Perhaps Shawn or others can add some color commentary.
