CLIMB SPEE DS.
Normal climbs are conducted at 75 to 80 MPH with flaps up and full
throttle, for best engine cooling. The mixture should
be
full rich unless
the engine is rough due to too rich a mixture. The best rate-of-climb
speeds range from 73 MPH at sea level to 65 MPH at 10, 000 feet.
If
an
obstruction dictates the use of a steep climb angle, the best angle-of
climb speed should be used with flaps up and full throttle. These speeds
vary from 57 MPH at sea level to 60 MPH at 10, 000 feet.
NOTE
Steep climbs at these low speeds should be of short
duration to allow improved engine cooling.
GO-AROUND CLIMB.
In
a balked landing (go-around) climb, the wing flap setting should
be reduced to 20° immediately after full power is applied. Upon reach
ing a safe airspeed, the flaps should be slowly retracted to the full up
position.
CRUISE.
Normal cruising is done at 65% to 75% of METO power. The set
tings required to obtain these powers at various altitudes and.outside
air temperatures can be determined by using your Cessna Power Com
puter or the OPERATIONAL DATA, Section
V.
Cruising can be done most efficiently at high altitude because of the
higher true airspeeds obtainable at the same power. This is illustrated
in the following table for 75% power.
