ill
enable
you
to
operete
your
Cessna
center
of
gravity
limitations.
To figure
le
Problem,
Loading
Graph,
and
Center
ollows:
Take the basic empty
weight
and
moment
from
appropriate
weight and
balance records carried
in
your
airplane,
and
onter thom
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
Problem. The moment
which
is
shown must be divided
by
1000
and
this
value
used as the
moment/ 1000
on the
toading
problem.
Use
the Loading
Graph to determine the
moment/
1000
for each
additional item to be
carried;
then
list
these on
the loading
problem.
NOTE
Loading Graph
information
for
the
pilot,
passengers
and
baggage
is based on seats
positioned
for average
occu-
pants
and baggage loaded
in the
center
of the
baggage
areas
as shown on the Loading Arrangements
diagram.
For
loadings which may differ
from
these,
the
Sample
Loading
Problem lists fuselage
stations for those items
to
indicate
their
forward and
aft
C.G.
range limitations
(seat
travel
and baggage area limitation), Additional
moment
calculations,
based on the actual weight and
C.G. arm
(fuselage
station) of the item being loaded. must be mad'e if
the
position
of
the Ioad is different from that
shown
on
the
Loading Graph.
Total the
weights a,nd moments/1000 and
plot
these values on the
Center
of
Gravity
Moment Envelope
to
determine whether the
point
falls
within
the envelope. and if the
loading is
acceptable.
