Peter,

echnically, at that altitude you
theoretically wouldn't need to, based on the POH.


Wrong. Most all POHs tell you to lean at any altitude AT CRUISE POWER
SETTINGS.

Wrong? Completely? So wrong that you found it so very important to follow
up to say so? Amazing. In any case...

Not all do. Many state or imply that leaning is not necessary below 3000'
or 5000', for example. And it may even be true that leaning isn't *really*
necessary, from an operational point of view. But engine will be much
happier if you do. I don't have the POH he's using, so I have no idea what
it says. My comments were offered purely in the hypothetical, so I don't
see how you can make an unqualified assertion that they were wrong.

My point is that, even if the POH says you don't need to lean, one ought to
anyway in this particular case. Do you disagree with the actual point, or
are you so hard up you find it necessary to critique embedded statements
that could be construed as being flatly incorrect, even when they aren't?
