Rich of Peak (ROP) vs Lean of Peak (LOP)/Engine operation

[Ernie Martin]

Kevin, on your last message above this one, the key word in item 1 is "mis-management". RAM, Lycoming and I are not saying that proper LOP operation -- be it via FADEC or a savvy and attentive pilot with an analyzer -- can damage the engine*. But mis-management can. And while Walter and George assert differently, there is general agreement by engine manufacturers and overhaulers that ROP operation on this type engine is easier to manage and far more tolerant of pilot mis-management.
