Cessna 182 1973 - Wing Leveler

WING
LEVELER
A
wing
leveler
may
be
installed
to
augment
the
lateral
stability
of
the
airplane.
The
system
uses
the Turn
Coordinator
for
roll
and
yaw
sensing.
Vacuum
pressure,
from
the
engine-driven
vacuum
pump,
is routed from
the Turn
Coordinator to
cylinder-piston
servo
units
attached
to the
aileron
control
system.
As
the
airplane
deviates
from
a
wing
level
attitude,
vacuum
pressure
in the
servo
units
is
increased
or
relieved
as
needed to
actuate
the
ailerons
to
oppose
the
deviations.
A
separately
mounted
push-pull
control
knob,
labeled
"WING
LVLR",
is
provided
on
the
left
side
of
the
instrument
panel
to
turn
the
system
on
and
off. A
"ROLL
TRIM"
control
knob
on
the
Turn
Coordinator
is
used
for manual
roll
trim
control
to
compensate
for
asymmetrical
loading
of
fuel and
passengers,
and
to
optimize
system performance
in
climb,
cruise
and
let-down.
