LONGITUDINAL LOADING OF CARGO
The large aft compartment of the Model 900 provides great
flexibility in the variety
of cargo loads it can
accommodate.
To determine the gross weight and center of gravity for a
given flight are within
limits, proceed as follows.
Obtain the Basic Weight and Moment from the Weight and Balance Record (Ref.
Figure 6-4).
Establish the weight of cargo load.
Determine the location of the cargo longitudinal CG (Ref. Figure 6-3)
Obtain the cargo moment:
Cargo Moment = Cargo Weight X Cargo CG
Perform weight and balance as previously described for
passenger configura
tion.

NOTE
:
The CG’s fall within the limits specified in Table 6
1; therefore, the loading meets
the longitudinal CG limits.
