6.4.3 CALCULATION OF LOADING CONDITION
1. Complete the form on the next page.
2. Divide the total moments from rows 4 and 6 by the related total mass to obtain the
CG positions.
In our example: empty tank: 167.5 kgm / 686 kg = 0.244 m
14,569 in.lb / 1512 lb = 9.64 in
full tank: 201.9 kgm / 728 kg = 0.277 m
17,582 in.lb / 1605 lb = 10.95 in
3. Locate the values in the diagram in Section 6.4.4 - PERMISSIBLE CENTER OF
GRAVITY RANGE. If the CG positions and related masses fall into the permitted area,
the loading condition is allowable.
Our example shows allowable loading conditions.
