By the way, have you got an electronic copy of the VNE Power On Limitations in KIAS, (temp against alltitude) placard which is screwed to the insrtument panel - that you could post here. I don't, but I do have a question for anyone who could help me with a quandry about it.
I can't believe the good folks at Agusta have made a school boy error, but I can't fathom the logic out either. I will of course apply the limits religiously regardless.
