WEIGHT AND BALANCE (Continued)
WEIGHT AND BALANCE RECORD (LOADING MANIFEST)
(Cont~nued)
NOTE
If weiaht to be loaded does not match one of the weight
incre6ents provided, and a more precise weight index is
needed. use the LOAD ITEM INDEX formula on the
backside of the Weight And Balance Record to calculate
the index. However. as shown in the
sam~le calculation
below for a
315-~ound load (instead of 300 pounds) in
cabin zone 1, minor weight variables do not affect the
weight index significantly. The ARM used in the following
calculation is the centroid of cabin zone 1 as shown on the
diagram on the backside of the record.
500
1000 - 12.6 = 987.4
The weight index of 987.4, when rounded to the next highest
number, would still result in the 988 given in the example above
for a 300-pounds load.
5. Add weight of pod cargo, pilot and passenger to sub-total weight
for cabin cargo and enter this value as the weight of the total
payload; the sum of all item indices recorded is the item index for
the total payload. For calculation purposes, enter only the last
three digits of the total in the item index columns.
6. Enter basic empty weight (from airplane weight and balance
information) in ITEM WEIGHT column for
aircraft empty weight.
Calculate weight index using the BASIC AIRPLANE INDEX
formula on the backside of the Weight And Balance Record. The
sample calculation below is for an airplane with a basic empty
weight of 4575 pounds and a C.G. arm of 185.03.
4575 X
(1 85.03 - 192) + 500
500
4575 X (-6.97)
+ 500 = 436.22
500
In the aircraft empty weight spaces for the airplane in this
sample, a weight of 4575 and an index of 436 would be entered.
