Piper ARCHER II - Weight and Balance Determination for Flight

PIPER AIRCRAFT CORPORATION SECTION 6
PA-28-181, ARCHER II WEIGHT AND BALANCE
6.7 WEIGHT AND BALANCE DETERMINATION FOR FLIGHT
(a) Add the weight of all items to be loaded to the basic empty weight.
(b) Use the Loading Graph (Figure 6-13) to determine the moment of
all items to be carried in the airplane.
(c) Add the moment of all items to be loaded to the basic empty weight
moment.
(d) Divide the total moment by the total weight to determine the C.G.
location.
(e) By using the figures of item (a) and item (d) (above), locate a point
on the C.G. range and weight graph (Figure 6-15). If the point falls
within the C.G. envelope, the loading meets the weight and balance
requirements. -

The center of gravity (C.G.) of this sample loading problem is at 91.5 inches
aft of the datum line. Locate this point (91.5) on the C.G. range and
weight graph. Since this point falls within the weight - C.G. envelope, this
loading meets the weight and balance requirements.
IT IS THE RESPONSIBILITY OF THE PILOT AND AIRCRAFT OWNER
TO ENSURE THAT THE AIRPLANE IS LOADED PROPERLY. © a&
