6.8 WEIGHT AND BALANCE EXAMPLE
The following example is provide as a guide for weight and balance
calculation and does not reflect a specific aircraft. The weight and balance
dataspecifictoeachaircraftmustbeperformed before each flight.
Assumingthefollowingbasicdatawehave:
Basic empty weight : 1470 Lbs
Empty weight moment: 1449.32 in-lbs/100
C of G (Empty): 98.6Iinches
From the following aircraft loading information we have:
Pilot: 200 lbs
Passenger: 185 lbs
Baggage area #1: 60lbs t HE
Baggage area #2: 40lbs
Fuel: 20 USG
Using the Weight and Balance Loading Graph of Figure (6.4) and the data
of Figures (6.5) and (6.6) we obtain the weight and balance data shown in
Figure( 6.8).
Intheexamplethe center of gravity location at take-offisfoundtobe:
CofG = 199510 in-lbs/1966. lbs
=101.5in
This point is found to be within the envelope of the graph “Weight and
Moment Limits” of Figure (6.7). Hence one can find that it lies in the
permissible range and therefore the planned loading is permissible.
