6-5. LAT ERAL WEIGHT AND BAL ANCE DE TER MI NA TION
z
The safe operation of this helicopter requires that it be flown within
the established lateral as well as longitudinal center of gravity limits.
z
It is therefore imperative that lateral center of gravity control be
exercised.
z All combinations of passenger loadings are permissible if gross
weight, -longitudinal, and lateral center of gravity considerations
permit.
z For passenger lateral center of gravity, refer to Fig. 6-4 and Table
6-1.
