6–6. PERMISSIBLE LATERAL LOADINGS – PASSENGER
CONFIGURATION
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 loadings are permissible if gross weight, longitudinal,
and lateral center of gravity considerations permit.
To determine the gross weight and center of gravity for a given flight are within
limits, proceed as follows.
Obtain the basic weight and longitudinal moment from The Basic Weight and Bal<
ance Record (Ref. Figure 6−4).
For pilot and passenger longitudinal and lateral center of gravity stations, see
Figure 6−2.

NOTE
: The CG’s fall outside the limits specified in Table 6–1; therefore, the loading
does not meet the lateral CG limits.
