Table 6.3-3
The plot on the diagram illustrated in Figure 6.3-3 demonstrates that the
CG is slightly forward of the mid position and borders on the maximum
allowable weight.
The flying CG can be calculated as follows:
Flying CG =
Total of moments
=
172 600
= 328.9mm
Total mass 524.7
The flying CG must be within the limits given in Section 2.6 .
