CRUISING

The cruising speed is determined by many factors including
power setting, altitude, temperature, loading and equipment in-
stalled on the airplane.
The normal cruising power is 75% of the rated horsepower
of the engine. True airspeeds which may be obtained at various
altitudes and power settings can be determined from the charts
in Section V of this handbook .
Use of the mixture control in cruising flight reduces fuel
consumption significantly, especially at higher altitudes. The
mixture should be leaned during cruising operation above 5000
feet altitude and at pilot's discretion at lower altitudes when
75% power or less is being used. If any doubt exists as to the
amount of power being used, the mixture should be in the FULL
RICH position for all operations under 5000 feet.
To lean the mixture, pull the mixture control until the engine
becomes rough, indicating that the lean mixture limit has been
reached in the leaner cylinders. Then enrich the mixture by
pushing the control towards the instrument panel until engine
operation becomes smooth. The fuel flow meter will give a close
approximation of the fuel being consumed.
