FLIGHT
CONTROL
SYSTEM
Dual
flight
controls
are
installed
in
the
Seneca
Ill
as
standard equip-
ment
The
controls
actuate
the
control
surfaces
through
a
cable
system.
The
horizontal
tail surface
(stabilator)
is
of the all
movable
slab
type
with
an
anti-servo
tab
mounted
on
the
trailing
edge.
This
tab,
actuated by
a
control
mounted
on
the
console
between the
front
seats,
also
acts
as a
longitudinal
trim tab
(refer
to
Figure 7-9)
The
ailerons
are
of the
Frise
type.
This
design
allows
the leading
edgeof
the
aileron
to
extend
into
the
airstream
to
provide increased
drag
and
improved
roll
control.
The
differential deflection
of
the
ailerons
tends
to
eliminate
adverse
yaw
in
turning
maneuvers
and
to
reduce the
amount
of
coordination
required
in
normal
turns.
The
vertical
tail
is
fitted
with
a
rudder
which
incorporates
a
combination
rudder
trim and
anti-servo
tab.
The
rudder trim control
is
located
on
the
control
console
between
the
front
seats.
The
flaps
are
manually
operated
and
spring
loaded
to return
to
the
retracted
position,
A
four-position
flap
control
lever
(Figure
7-9)
between
the
front
seats
adjusts
the
flaps
for
reduced
landing
speeds
and
glide
path
control. The
flaps
have
three
extended
positions
-
10,
25
and 40
degrees
-
as
well
as
the
fully
retracted
position.
A
button
on
the end
of
the lever
niust
be
depressed
before
the
control
can
be moveds A
past
center
lock incorporated
in
the
actuating linkage
holds
the
flap
when
it is in the
retracted
position
