WEIGHT
AND
BALANCE
The
following information
will
enable
you
to operate
your
Cessna
within
the
prescribed
weight and center of
gravity
limitations.
To
figure
weight and
balance,
use
the
Sample
Prob1em, Loading Graph, and
Center
of Gravity
Moment Envelope
as
follows:
Take
the
basic
empty
weight
and moment
from appropriate weight and
balance
records
carried
in
your
airplane,
and
enter them in the column
titled
YOUR
AIRPLANE
on the
Sample
Loading
Problem.
NOTE
In addition
to the basic
empty weight
and
moment
noted
on
these records,
the c.
g.
arm
(fuselage
station)
is also
shown,
but
need not be
used on the
Sample
Loading
Prob-
lem.
The
moment which
is
shown
must
be divided
by
1000
and
this
value
used as
the
moment/1000
on
the
loading
problem.
Use the
Loading
Graph
to
determine
the moment/1000
for
each
addi-
tional
item
to be carried;
then
list
these
on
the loading
problem.
NOTE
Loading
Graph
information
for
the
pilot,
p:uisengers,
and
baggage
is based
on
seats
positioned
for average
occupants
and
baggage
loaded
in
the
center
of the bag-
gage
areas
as shown on
the
Loading
Arrangements dia-
gram.
For
loadings
which
may
differ
from these,
the
Sample Loading
Problem
lists
fuselage stations
for these
items to
indicate
their forward
and aft
c.
g.
range
limi-
tations
(seat

).
Ad-
ditional moment
calculations,
based on
the
actual weight
and c.
g.
arm
(fuselage
station) of
the item
being
loaded,
must be
made
if the
position
of
the
load
is different from
that
shown on the
Loading
Graph.
