CHEROKEE "E" SECTION III
temperature (EGT) gauge, a more accurate means of leaning is
available to the pilot. For best power mixture, lean the mixture
until the peak EGT is reached, then enrich the mixture until the
temperature drops a minimum of 25° F. For best economy mixture,
lean until the peak EGT is reached and continue to lean until
the temperature drops a minimum of 25° F. Do not lean above 75%
power.
In order to keep the airplane in best lateral trim during
cruising flight, the fuel should be used alternately from each
tank. It is recommended that one tank be used for one hour after
take-off, then the other tank be used for two hours, then return
to the first tank, which will have approximately one and one half
hours of fuel remaining if the tanks were full at take-off. The
second tank will contain approximately one half hour of fuel. Do
not run tanks completely dry in flight.
APPROACH AND LANDING
Before landing check list:
1. Fuel - on proper tank
2. Electric fuel pump - ON
3. Mixture - set
4. Flaps - set (115 MPH MAX)
5. Seat belts - fastened
The airplane should be trimmed to an approach speed of
about 85 MPH with flaps up. The flaps can be lowered at speeds
up to 115 MPH, if desired, and the approach speed reduced 3
MPH for each additional notch of flaps. Carburetor heat should
not be applied unless there is an indication of carburetor icing,
since the use of carburetor heat causes a reduction in power
which may be critical in case of a go-around. Full throttle op-
eration with heat on is likely to cause detonation.
The amount of flap used during landings and the speed of the
aircraft at contact with the runway should be varied according to
the landing surface and conditions of wind and airplane loading.
