LANDING.
(1)
Before
landing,
push
"WING
LVLR"
control
knob full in
to the
off
position.
EMERGENCY
PROCEDURES
If
a
malfunction
should
occur,
the
system
is easily
overpowered
with
pressure
on
the
control
wheel.
The system
should
then
be
turned
off.
In
the
event
of partial
or complete
vacuum
failure,
the
wing leveler
will auto-
matically
become
inoperative.
However,
the
Turn
Coordinator
used with
the
wing leveler
system
will not be
affected
by loss
of vacuum
since
it is
designed
with a "back-up"
system
enabling
it
to
operate
from either
vac-
uum or electrical
power
in
the
event
of
failure
of one of
these
sources.
OPERATING
NOTES
(1)
The wing leveler
system
may
be
overpowered
at any
time
without
damage
or
wear.
However,
for
extended
periods
of maneuvering
it
may
be desirable
to turn the
system
off.
(2)
It is
recommended
that
the
system
not
be engaged
during
take-off
and
landing.
Although
the
system
can be easily
overpowered,
servo
forces
could
significantly
alter
the
manual
"feel"
of
the
aileron
control,
especially
should
a malfunction
occur.
