Normal climbs are performed at 90 to 100 MPH with flaps up and
reduced power (down to 24 inches of manifold pressure and 2500 RPM)
for increased passenger comfort due to lower noise level. The mixture
should be full rich below 3000 feet and may be leaned above 3000 feet for
smoo ther e ngi ne op e rat i on. The m axi m um ra te-o f-cl imb s p eed s rang e
from 92 MPH at sea level to 83 MPH at 10, 000 feet. If an obstacle dic¬
tates the use of asteep climb angle, an obstacle clearance speed of 77/
MPH should be used with flaps up and full throttle at all altitudes.

Normal cruising is performed between 55% and 75% power. The cor¬
responding power settings and fuel consumption for various altitudes can
be determined by using your Cessna Power Computer or the Operational
Data in Section VI.
The Cruise Performance table shown on the following page iliustrates
the time airspeed and miles per gallon during cruise for various altitudes
and percent powers. This table should be used as aguide, along with the
available winds aloft information, to determine the most favorable altitude
and power setting for agiven trip. TJie selection of cruise altitude on the
basis of the most favorable wind conditions and the use of low power set¬
tings are significant factors that should be considered on every trip to
reduce fuel consumption.
The tachometer is marked with agreen arc from 2100 to 2700 RPM
with astep at 2500 RPM. The use of 2500 RPM will allow 75% power at
altitudes up to 8000 feet on astandard day. For hot day or high altitude
conditions, the cruise RPM may be increased to 2700 RPM. Cruise at
2700 RPM permits the use of 75% power at altitudes up to 10, 000 feet on a
standard day. However, for reduced noise levels it is desirable to select
lowest RPM in the green arc range for agiven percent power that will
I )vide smooth engine operation.
