You're welcome, mate. Just to clarify a few points:
C of G Limits : Just looked up our AOM, and the outer limits for the CG band are actually 16 to 30. This corresponds to the green band for setting the mac on the pedestal. But like I mentioned previously, in normal operations we tend to see a range between 16 and 22 on our typical flights.
Obviously, depending on no. of pax, baggage, fuel, etc, your figures may vary, but as long as they are within whatever limits your airline works to, should be fine.
Also, like I mentioned previously, we tend to load the rear holds before the front holds, but with one very important proviso. Here is an extract from our AOM:
The following distribution of the load in the cargo compartments is recommended for CG planning:
– 15 pax or less: All load in cpt 1.
– More than 15 pax: plan for 200 kg in CPT 1, then load in CPT 4 until full, then in CPT 3. When CPT 3 is full, CPT 1 and CPT 2 may be used.
CAUTION: Forward galleys and forward holds must be loaded first and unloaded last due to the
danger of aft tipping
As you already know, there is no physical separation as such between holds 3&4, and 1&2,........but we load the initial 200 in the far front of holds 1&2, and then follow the rest of the guidelines as stated above.
cheers, mate
