DESCRIPTION
NOTE
When
the fuel
selector
valve handle is in the BOTH
position
in
cruising flight, unequal fuel flow from each tank
may
occur
if
the
wings
are not
maintained exactly
level.
Resulting
wing
heaviness
can be
alleviated gradually
by
turning the selector valve handle
to the tank in the
"heavy"
wing.
NOTE
It is not
practical to
measure the time required
to
consume
all of the fuel in
one tank, and, after switching
to
the
opposite tank, expect an equal duration from the
remaining
fuel. The airspace in both fuel tanks is
interconnected by
a
vent line and,
therefore, some sloshing
of fuel
between
tanks can be expected when the tanks are nearly full
and
the wings are
not
level.
NOTE
Unusable
fuel is at a
minimum due
to the design of the
fuel
system.
However,
with 1/4 tank
or
less,
prolonged
uncoordinated flight such as slips or skids can uncover
the
fuel tank
outlets causing
fuel
starvation
and
engine
stoppage.
Therefore,
with
low
fuel
reserves,
do not
allow
the airplane
to
remain
in
uncoordinated flight
for periods
in
excess of one minute.
FUEL DRAIN VALVES
The fuel system is
equipped
with
drain
valves to provide a
means
for the
examination
of fuel in the
system
for
contamination
and
grade.
The system should be
examined
before each flight and
after
each refueling, by
using the
sampler cup
provided to
drain fuel
from
each wing tank sump, the
fuel
reservoir sump,
the fuel
selector
drain and
the fuel
strainer sump.
lf
any
evidence
of
fuel
contamination is found, it must be
eliminated in
accordance
with
the
Preflight lnspection checklist
and
the discussion in Section
I
of
this
publication. lf takeoff weight
limitations
for the next flight
permit,
the
fuel tanks should be filled after each flight to prevent condensation.
