MODEL 172R
|RH
PANEL LAYOUT
|
The RH panel contains the hour
meter,
ELT switch, and room for
expansion of indicators and other avionics equipment. Below this
sub panel are the glove box, cabin heat and
cabin air controls, and
wing flap switch.
CENTER PEDESTAL LAYOUT
The
center
pedestal, located below the
center
panel, contains the
elevator trim control wheel, position
indicator, handheld
microphone
bracket and fuel shutoff valve control. The fuel selector
valve handle
|
is located at the base of
the pedestal.
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 arc of approximately 10° each side of
center. By
applying either left or right brake, the degree
of
turn
may be
increased up to 30°
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 differential
braking
and nose wheel steering during taxi, is approximately 27
|feet.
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.
Care
should be
exercised
to
ensure that
pressure
is exerted only
on
the bulkhead
I
area and not
on skin between the bulkheads. Pressing down
on the
horizontal stabilizer is
not
recommended.
