A340 FE part computed GW and CG

[HazelNuts39]

One of several ways to do it is by a process called 'iteration':

Step 1: Assume a CG position
Step 2: Compute Gross Weight
Step 3: Compute the horizontal stabilizer position for the computed GW and assumed CG
Step 4: Compare the computed to the actual position of the horizontal stabilizer.
- If the difference is less than a certain tolerance go to step 5, else -
- adjust assumed cg position and repeat steps 2, 3 and 4.
Step 5: Output GW and CG

Another method is interpolation:
Step 1: Compute GW and THS position for the CG on the forward limit
Step 2: Compute GW and THS position for the CG on the aft limit
Step 3: Interpolate GW and CG for the actual THS position
