6.4.3 CALCULATION OF LOADING CONDITION
1. Complete the form on the next page.
2. Divide the total moments from rows 11 and 14 by the related total mass to obtain the
CG positions.
In our example: empty tanks: 5003.65 kgm/2035 kg = 2.459 m
434,297 in.lb/4486 lb = 96.81 in
with fuel in tanks: 5611.55 kgm/2241 kg = 2.504 m
487,061 in.lb/4940 lb = 98,60 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.
NOTE
If the optional de-icing system OÄM 62-002 is installed, the
following must be observed:
The consumption of fuel causes a forward movement of the
CG. The consumption of de-icing fluid causes a rearward
movement of the CG. Depending on the fuel flow and de-icing
fluid flow, the overall movement of the CG can be a forward
or a rearward movement. In order to cover all possible cases,
the following table must be completed twice: with (as shown
in the example) and without considering the on-board de-icing
fluid. All four CG positions (fuel tank full/empty, de-icing fluid
tank full/empty) must fall into the permitted area.
