Cruise Leaning
Exhaust gas temperature (EGT) may be used as an aid for mixture
leaning in cruise flight. For “Best Power” use 75% power or less. For
“Best Economy” use 65% power or less. To adjust the mixture, lean to
establish the peak EGT as a reference point and then adjust the
mixture by the desired increment based on the following table:
Under some conditions, engine roughness may occur while operating
at best economy. If this occurs, enrich mixture as required to smooth
engine operation. Any change in altitude or Power Lever position will
require a recheck of EGT indication.
