SECTION 7
AIRPLANE
&
SYSTEMS DESCRIPTION
CESSNA
MODEL
172R
AVIONICS MASTER
SWITCH
Electrical power
for each
Avionics
Bus
is
supplied from a primary
Electrical
Bus.
For
airplane
serial
numbers 17280001 through
17280983, except
for
certain
non-U.S.
certified
airplanes, both
Avionics
Buses
are controlled
by
a
single-section rocker-type
Avionics
Master switch.
At serial
number
17280984
and
on,
a
two-
section
or
"split" rocker-type
Avionics
Master switch controls power
to
each Avionics Bus
independently. Placing
the
rocker
in
the up
(ON)
position provides power
to
the Avionics Bus.
Placing
the
rocker in
the
down (OFF)
position
removes
power from
the Avionics
Bus. The Avionics
Master switch is
located
on the lower
left
side of
the instrument
panel.
For
airplane
serial numbers
17280001
through
17280983,
aircraft certified
outside
the
United
States
can
have a
two-
section or "split" Avionics Master
switch.
The two-section
Avionics Master switch enables
independent operation of
Avionics Bus
1
and Avionics Bus
2.
With
the
Avionics
Master
rocker
in
the
OFF position, no electrical
power
is provided
to
the
avionics,
even
when
the
Master switch or
the
individual avionics
component
equipment switches are
in
their
ON positions.
The Avionics
Master switch
(both sides,
if two-section)
should
be
placed in
the
OFF
position
before
switching the
Master
switch ON or
OFF,
starting
the engine,
or
applying an external
'
power
source.
Each avionics
bus also incorporates a
separate
circuit breaker
installed between the primary bus
and
the avionics
master
switch. In
the
event
of
an
electrical
malfunction,
this breaker will trip and take
the effected avionics bus off-line.
AMMETER
|
The
ammeter/vacuum
gage is located on the lower left side
of the
instrument
panel.
It indicates the
amount of
current,
in amperes,
from the alternator
to
the battery
or
from
the battery
to
the airplane
electrical
system.
When the
engine is operating
and the
master
switch is turned
on,
the
ammeter
indicates the
charging
rate
applied
to
the battery.
In the
event
the
alternator
is
not
functioning
or the
electrical load exceeds
the output of the alternator, the
ammeter
indicates the battery discharge rate.
