Approach And Landing - Piper CHEROKEE 180 Owner's Handbook Manual

CHEROKEE 180 SECTION III
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.
If the
airplane
is equipped
with the
optional exhaust
gas
temperature
(EGT) gauge,
a more accurate means of
leaning is
available
to the
pilot. For
this
procedure,
refer
to
the
AVCO
Lycoming
Operator's
Manual.
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
4.
Seat backs
erect
2.
Mixture
-
rich
5. Flaps
-
set (115 MPH)
3.
Electric fuel pump
-
on
6. Fasten
belts/harness
7.
Air
conditioner
-
off
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 operation with
heat on
is likely
to cause
detonation.
The
amount of
flap
used
during landings
and
speed
of the aircraft
at contact with the runway
should
be
varied
according to the
landing
surface and conditions
of wind and airplane
loading. It is generally
good
practice
to contact
the
ground
at
minimum
possible
safe speed
consistent with
existing
conditions.
