6 − 4. WEIGHT AND BALANCE DETERMINATION − PASSENGER
CONFIGURATION
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 (Ref. Figure 6−2, and
Figure 6−7).
Add above items (see Example I).
Determine corresponding center of gravity for gross weight by dividing total
moment by gross weight. This computation must be done with zero fuel
gross weight and with mission fuel gross weight (see Example I).
NOTE
: If loadings are not symmetrical about the aircraft centerline, determine lateral
CG’s as described in Paragraphs
6−6 and 6−7
.
Weight and balance must be computed for minimum front seat
weight prior to loading any passengers in rear seats with only pilot
in front. Ballast, if required, must be carried.
NOTE
: Ballast may be carried in the utility stowage compartment or stowed and secured
by seat belt and shoulder harness in opposite front seat. Ballast may consist of
shot, sandbags, or similar material, adequately contained and secured.
