This RPM setting is not allowed for airplanes equipped with a 3-blade propeller Type MTV-9-B-C/
C 198-25 operated in the normal category, in which noise protection requirements must be complied
with.
N O T E
1* For temperatures above/ below Standard (ISA), increase/decrease Range 1,7% and
Endurance 1,1% for each 10°C (18°F) above/below Standard Day Temperature for
particular altitude.
2* Leaning with exhaust gas temperature (EGT) gage:
For the adjustment "Best Power", first lean the mixture to achieve the top exhaust
temperature (peak EGT) and then enrich again until the exhaust temperature is 100°F
lower than peak EGT.
For the adjustment "Best Economy", simply lean the mixture to achieve the top
exhaust temperature (peak EGT).
W A R N I N G
Risk of engine overheating.
Always return the mixture to full rich before increasing power settings.
