WING
FLAP SYSTEM
The single-slot type wing flaps
(see
figure
7-3), are extended or
retracted
by
positioning
the
wing flap switch lever
on
the
instrument panel
to the
desired
flap
deflection position. The switch lever
is
moved up or
down
in
a
slotted panel that provides mechanical
stops at
the
10o
and 20"
positions. For flap settings greater than
10o,
move the
switch lever to the
right
to
clear
the
stop
and
position it
as
desired.
A scale
and
pointer
on the
Ieft
side of the
switch lever indicates flap travel in
degrees. The
wing flap
system
circuit
is protected by
a
15-ampere
circuit breaker, labeled
FLAP'
on
the Ieft
side
of the switch
and
control panel.
LANDING GEAR

tanding gear
is
of

gear struts
and
the
air/oil
nose gear
shock strut. Each
main gear wheel
is
equipped
with
a hydraulically
actuated single-disc brake
on the inboard side of each wheel, and
an
aerodynamic
