WEIGHT AND BALANCE.
The
following
information will enable you to
operate
your
Cessna
within
the
prescribed
weight and
center of gravity
limitations.
To figure
the weight and
balance for your particular
airplane,
use
the Sample
Problem, Loading
Graph,
and Center of
Gravity
Moment Envelope as
follows:
Take the licensed
Empty
Weight and
Moment/1000 from
the
Weight
and Balance
Data sheet,
plus
any
changes noted
on
forms
FAA-337
carried in
your
airplane,
and
write
them down in
the
proper columns.
Using
the
Loading Graph,
determine
the moment/1000
of each item to
be carried. Total the weights and moments/1000 and use
the
Center
of
Gravity Moment Envelope
to determine
whether the point falls
with-
in
the
envelope,
and if the
loading
is acceptable.
