LANDING
LIGHTS
If
landing
lights
are
to
be
used
to
enhance
the
visibility
of
the
airplane
in
the
traffic
pattern
or
enroute,
it is
recommended that
only
the
taxi
light
be used. This
will
extend the
service
life
of
the
landing
light
appreciably.
TAKEOFF
POWER
CHECK
It is
important
to
check
full
throttle
engine
operation
early
in
the
takeoff
roll.
Any sign
of
rough engine
operation
or
sluggish engine
acceleration is
good
cause
for
discontinuing
the
takeoff.
If
this
occurs,
you
are
justified
in
making
a
thorough
full
throttle
static
runup
before
another
takeoff
is
attempted.
The
engine
should
run
smoothly
and
turn
approximately
2065
-
2165
RPM
with mixture
leaned
to
provide
maximum
RPM.
Full
throttle
run
ups
over
loose
gravel
are
especially
harmful
to
propeller
tips.
When
takeoffs
must
be made
over
a
gravel
surface,
it
is
very
important
that
the throttle
be
advanced
slowly.
This allows
the
airplane
to
start
rolling
before
high
RPM
is
developed,
and
the
gravel
will
be
blown
back
of
the
propeller
rather
than
pulled
into it.
When
unavoidable small
dents
appear
in
the
propeller
blades,
they
should be
immediately
corrected
as
described
in
Section
8
under
Propeller
Care.
Prior
to
takeoff from
fields
above
3000
feet
elevation,
the
mixture
should be
leaned
to
give
maximum
RPM in
a
full
throttle,
static
runup.
After
full
throttle is
applied,
adjust
the
throttle
friction
lock
clockwise
to
prevent
the
throttle
from
creeping
back
from
a
maximum
power
position.
Similar
friction
lock
adjustments
should
be
made
as
required
in
other
flight
conditions
to
maintain
a
fixed
throttle
setting.
