6-4. LONGITUDINAL WEIGHT AND BALANCE DETERMINATION
To determine that the gross weight and longitudinal center of gravity
(fore and aft) for a given flight are within limits, proceed as follows
Obtain aircraft delivered weight and moment from the Weight and
Balance Record inserted in this section.
Determine weights and moments of useful load items (see
Example I, Fig. 6-3, and Table 6-1).
