Double Bogey
I don't see where John Dixon or John Eacott are advocating the use of 60% Nr. My understanding is that John Dixon was relaying research findings.
FYI - LOW RPM AT HEIGHT IS A STONE COLD KILLER. All helicopter pilots know this and every one should be taught how to avoid and recover from this situation.
You've just said it's a "stone cold killer" but then you say everyone should be taught to recover from it!
Are you also trying to have it "both ways"?
Talking numbers beyond that published in the RFM and clearly printed on the NR gauge demonstrates that you know the price of everything and the value of nothing.
What
exactly do you mean by that statement?
This chest beating arse was responsible for the demise of the S92 in Newfoundland!
Who are you referring to and in what context?
All in all, a somewhat confusing post.
