PA-32-301T, TURBO SARATOGA WEIGHT AND BALANCE
6.11 INSTRUCTIONS FOR USING THE WEIGHT
AND BALANCE
PLOTTER
This plotter is provided to enable the pilot quickly and
conveniently
to:
(a)
Determine the total weight
and C.G. position.
(b)
Decide how to change his load if his first loading is
not within
the
allowable envelope.
Heat can warp or ruin the plotter
if it is
left
in the sunlight. Replacement
plotters may be purchased from Piper dealers and distributors.
The "Basic Empty Weight and
Center
of Gravity"location
is taken from
the Weight and Balance Form(Figure 6-5), the Weight and Balance Record
(Figure 6-7)
or
the latest FAA major
repair
or alteration form.
The plotter
enables the user to
add weightsandcorresponding
moments
graphically. The effect of adding or disposing of useful load can easily be
seen. The plotter
does not cover the situation
where cargo is
loaded in
locations
other than on the seats or
in the baggage compartments.
Brief instructions are given on the plotter itself. To
use
it, first plot
a
point on the grid to locate the basic weight and C.G. location. This can be put
on more
or
less permanently
because it
will not
change
until
the airplane is
modified.
Next, position the zero weight end of any one of the loading slots
over this point. Using
a
pencil, draw a line along the slot to the weight which
will
be carried in that location. Then position the
zero
weight end of the
next
slot over
the end of this line and
draw
another line representing
the weight
which will be located
in this second position.
When all the loads have been
drawn in this manner,
the
final end
of the
segmented
line locates the total
load and the C.G. position of the airplane
for takeoff. If this point is
not
within the allowable envelope it will be necessary to
remove
fuel, baggage,
or passengers
and/
or to
rearrange
baggage and passengers
to get the final
point to fall
within
the envelope.
Fuel burn-off does not significantly affect the center of gravity.
