Ya I've tried that I have tried that and ive got SIA e-manual but there are still some specific values such as the CG limits that I cannot find. It states that the CG limits chart can be found in the aircraft flight manual thats why im asking for it now. After searching the internet for days, I found out that there is no free copy.... its cost about $150 for an AFM!! And I've seached in the library but still cant find it thats why Im desperately calling for help now.
