with
the right
side
of the
panel
containing
space for additional
instruments
and

at
the lower edge
of
the
instrument
panel
contains the
primer,
master

ignition
switches,
avionics
power
switch,
circuit breakers,
and
electrical
switches
on
the left
side, with
the

side
of the switch
and control
panel
contains
the
wing flap switch lever
and
position indicator, cabin
heat

provides
a bracket
for
the microphone.
A
rudder

installed
below the
trim wheel
and microphone
bracket.
The fuel selector

is
located
at the base of
the
pedestal.
A
parking

concerning
the instruments,
switches, circuit breakers,
and
controls

GROUND CONTROL
Effective
ground
control
while taxiing
is
accomplished
through nose
wheel
steering by
using
the
rudder
pedals; left
rudder
pedal
to steer
left and
right
rudder
pedal
to
steer right. When a rudder
pedal
is depressed,
a
spring-loaded
steering
bungee
(which
is
connected to the nose
gear
and
to
the
rudder bars)
will
turn the nose
wheel
through
an
a,rc of
approximately
10o
each side of center.
By applying
either
Ieft
or
right brake,
the degree
of
turn
may be
increased
up
to 30o each
side of
center,
Moving the
airplane
by hand is most
easily accomplished
by attaching
a tow bar to
the nose
gear
strut. If
a tow
bar
is
not
available,
or
pushing is
required,
use
the
wing struts
as
push points.
Do
not
use
the vertical
or
horizontal
surfaces
to move
the
airplane.
If the airplane
is to be towed
by
vehicle,
never
turn the
nose wheel more than
30"
either
side of center
or
structural
damage
to the nose
gear
could
result,
The
minimum
turning
radius of the
airplane, using differentiat
braking
and nose
wheel
steering during
taxi, is
approximately
27
feet
5 and
1/2
inches.
To obtain
a
minimum radius turn
during
ground
handling,
the
airplane
may
be rotated
around either
main landing gear
by
pressing
down
on
a tailcone
bulkhead
just
forward
of
the horizontal
stabilizer
to
raise
the
nose wheel
off
the
ground.
