The only things that start more arguments than flying "lean of peak" are
slips with flaps and a discussion of lift.


It's not only LOP, it's that 50 or 75 ROP is usually a bad place.

Part of the reason that "lean of peak" starts so many arguments, and that
they quickly become so acrimonious, is the failure of contributors to state
whether they are talking about peak rpm or peak egt, what instruments are
available, what power level, and what engine ane prop.

There would still be discussions, and they would still be heated; but there
would be a POSSIBILITY that at least two of the contributors MIGHT be
discussing the same subject.
