6–6. PERMISSIBLE LATERAL LOADINGS
Safe operation of this helicopter requires that it be flown within established
lateral as well as longitudinal center of gravity limits.
It is therefore imperative that lateral center of gravity control be exercised.
All combinations of internal and external loadings are permissible if gross
weight, longitudinal, and lateral center of gravity considerations permit.
For crew and passenger lateral center of gravity, see Figure 6−2.
6–7. LATERAL LOADING OF CARGO
To determine if the gross weight and lateral center of gravity for a given flight
are within limits. Proceed as follows:
Find weight of load.
Determine lateral location (station) of load center of gravity.
Measure load distance from aircraft centerline (lateral station zero), right
(+); left (−).
Obtain the lateral load moment as follows:
Lateral moment = weight
X
lateral station. (See Example III.)
