FUEL CROSSFEED (One Engine
Inoperative
Only)
The fuel
lines
for
the engines are
interconnected
by cross-
feed lines.
During
normal
operation
each
engine
uses its
own
fuel pumps to
draw
fuel
from- its respective
wing
fuel
system. However, on
emergency
crossfeed
operations
either
engine
can
consume
the
available
fuel
from
the
op-
posite side.
The fuel crossfeed system is provided
for
use
during
emer-
gency conditions. The system
cannot
be used to
transfer
fuel from one
wing
system to
the
other.
The
procedure
for
using the crossfeed system is described in
the
EMER-
GENCY PROCEDURES section.
AUXILIARY FUEL PUMPS
An
individual
two-speed
electric
auxiliary
fuel
pump
is pro-
vided for each engine. HIGH pressure, OFF or
LOW
pres-
sure is selected
with
each
auxiliary
fuel
pump
switch
on
the
pilot's
subpanel. High pressure is used
for
providing
fuel
pressure before starting, and provides
near
maximum
en-
gine performance, should
the
engine-driven
pumpfail.
Low
pressure may be used in any
operating
mode to
eliminate
pressure
fluctuations
resulting
from
high
ambient
temper-
atures and/or
high
altitudes. The
high
pressure
position
should not be selected
while
the
engine
is
operating
except
in the event of
engine-driven
pump
failure
since
the
high
pressure mode supplies a
greater
pressure
than
can be ac-
cepted by the
injection
system
during
normal
operation.
FUEL
OFF-LOADING
When installed, a visual fuel level sight gage in each wing
leading edge,
outboard
of
the engine nacelle, can be used
for
partial
fill
ing or off-loading
of
fuel. Th is
gage
is to
be used
only
when
it
reads
within
the calibrated area.
FUEL REQUIRED FOR FLIGHT
Flight
planning
and
fuel
loading is
facilitated
by
the
use of
fuel
quantity
indicators
that
have been
coordinated
with
the
