Is it necesary to enter the CG of the A/C in the FMC PERF INIT page?Thanks,

The FMC calculates it.See pages 1-3 and 12-21

Hi Gents,Unfortunately the FMC does not calculate the CofG - as in the its position with relation to the MAC (Mean Aerodynamic Chord). It is presented as a %of MAC. This will be provided to the crew on a load sheet of some kind and they enter that figure into the FMC and it then provides the correct STAB TRIM setting which the subsequently set as part fo the preflight duties.ATB,

Thanks Brad, but I knew that already. :) ;)So, that's why I asked about entering that data in the FMC PERF INIT page.
