SECTION

NORMAL
PROCEDURES
(AMPL.IFIED
PROCEDURES)
If
synchronized operation
is
lost
during
large
power
changes,
manually
re-synchronize the propeller controls
as
closely
as
possible
and
synchro-
nized operation should reoccur. Securely tighten the
quadrant
friction
lock,
then
adjust the phasing
knob
as
desired.
During
the descent, the mixtures should
be
gradually enrichened to
maintain
smooth
engine operation. This
procedure
will
provide
sufficient
fuel flow for the descent;
however,
if
a higher
power
setting
(i.e.
balked
landing)
is
required before landing,
the
mixtures
must
be
readjusted to
obtain the correct fuel flow.
To
prevent confusion in interpreting
which
lO,OOO-foot
segment
of
alti-
tUde
is
being displayed
on
the altimeter, a striped
warning
segment
is
exposed
on
the face of the altimeter
at
all
altitudes
below
10,000
feet.

If
fuel
has
been
consumed
at
uneven
rates
between
the
two
main
tanks
because
of
prolonged engine inoperative
flight,
it
is
desirable to balance
the fuel load
by
operating
both
engines
from
the
fullest
tank.
However,
if
there
is
sufficient
fuel in
both
tanks,
even
though
they
may
have
unequal
quantities,
it
is
important to switch the
left
and
right fuel
selectors
to
the
left
and
right
main
tanks, respectively; feel for detent;
and
check
the
auxiliary fuel
pumps
ON
for the landing. This
will
provide
an
adequate
/"""'",
fuel flow to
each
engine
if
a
balked
landing
is
necessary.

Refer to Section 5 for speeds

Landing
gear extension before landing
is
easily
detected
by
a
slight
change
in airplane
trim
and
a
slight
"bump
II
as
the gear locks
down.
Illu-
mination of the
gear-down
indicator
lights
(green)
is
further proof
that
the gear
is
down
and
locked.
The
gear
unlocked
indicator
light
(red) will
illuminate
when
the gear uplocks are released
and
will
remain
illuminated
while the gear
is
in
transit.
The
unlocked
light
will extinguish
when
the
gear
has
locked
down.
If
it
is
reasonably certain that the gear
is
down
and
one
of
the
gear-down
indicator
lights
is
still
not illuminated, the
malfunction could
be
caused
by
a
burned
out
light
bulb. This
can
be
checked
by
pushing the
press-to-test
button.
If
the
bulb
is
burned
out,
it
can
be
replaced with the
bulb
from
any
post
light,
Or
the landing gear
unlocked indicator
light.
A simple last-minute recheck
on
final
approach
should confirm
that
all
applicable switches are on, the
gear-down
indicator
lights
(green) are
illuminated, the gear
unlocked
indicator
light
(red)
is
extinguished, the
propeller controls are
full
forward,
and
the mixtures are
set
for
smooth
operation.
