brake, pull
back on the
brake
lever to
disengage
the
catch
mechanism;
then allow
the
handle
to swing
forward.
CONTROL
SYSTEM
Dual
controls
are
provided
as standard
equipment
with
a cable
system
used
between
the controls
and
the surfaces.
The
horizontal
tail
is
of the all movable
slab type,
with
an
anti-servo
tab
acting
as
a
longitudinal
trim tab. It
is
actuated
by
a
control
on the cabin ceiling.
The stabilator
provides
extra stability
and
control
with
less
size,
drag,
and
weight
than conventional
tail surfaces.
The
differential
action
of
the
ailerons
tends
to eliminate
adverse
yaw in
turning
maneuvers
and
reduces the amount
of coordination
required
in
normal turns.
The
flaps
are
manually
operated,
balanced for light
operating
forces
and
spring
loaded
to turn to the
up
position.
A
past-center
lock
incorporated
in
the
actuating
linkage holds
the
flap
when
it is in
the up
position
so that
it
may
be
used
as a step
on
the
right
side. The
flap
will
not
support
a step
load
except
when
in
the
full
up
position,
so
it
must
be
completely
retracted
when
used as a step.
The
flaps have
three
extended
positions,
10, 25 and 40
degrees.
FUEL SYSTEM
Fuel
is
stored
in
two twenty-five
gallon
tanks which are secured to
the
leading
edge structure
of each wing
by
screws
and
nut
plates
to
allow easy removal
for
service or
inspection.
The standard
quantity
of
fuel is 36 gallons for
the Cherokee
140
"D."
To obtain
the standard
quantity
of
fuel, fill
the tanks
to the
bottom
of
the
filler
neck
indicator.
An auxiliary
electric
fuel pump is provided for
use
in
case of
failure
of the engine
driven pump.
The electric
pump
should
be
on
for
all
take-offs
and
landings
and when
switching
tanks,
Each
tank
has
an
individual quick drain located
at the
bottom,
inboard
rear corner,
and should
be drained
to check
for
water
before
each
flight.
The
fuel
strainer
is
equipped
with
a
quick drain
and
is
located
on the
front lower left
corner
of the
firewall.
This strainer
should
be
drained
regularly
to
check
for
water
or
sediment
