Newps,

No. Lean above 5000 as a general rule.


I would say 3000. But that's pretty much a matter of taste. What's
important is: we're talking density altitude!

You are in agreement with the POHs for the C152 and Tomahawk, which are the
two that I recall at the moment. IIRC, that involved leaning to peak RPM at
full throttle--part throttle operation was another matter. One of them
specifically authorized 25 RPM lean of peak for reduced power operation,
such as transitioning at 60% power--which my rather old instructor refused
to believe even when shown!

Amusing but true. He was quite serious, and the same debate is still
raging--25 years later!!!
