This weekend the Cessna Pilots Ass'n put on one of their 2-day Systems &
Procedures classes at Sporty's in Batavia Ohio. This one was for 182S,
182T and T182S/T owners. About 20 owners attended, and it was well worth
the trip and cost.

Anyhow, one of the best tips I picked up from John Frank was to cruise my
engine more over-square than I usually do, i.e., instead of 26"/2400 RPM
or 25"/2300 RPM, run it 27"/2200 RPM or 26"/2100 RPM.

I tried this on the way home and found I got the same performance, maybe a
hair better, by trying to get the same % horsepower with more MAP and less
RPM. It was quieter and the fuel flow was down a smidgen, too. According
to John, most of the advantage comes from less internal mechanical
horsepower loss at the lower RPM settings.

This is probably not news to a lot of you folks, but it was to me, and
it's the way I'm going to run from now on.


Is John with the CPA or Lycoming? Just wondering what Lycoming thinks of the
recommendations.
