EFB and Fuel page of FMC

  • Hi Martyn,
    great plane if I didn't have any issues with loading it correctly. My problem:
    The EFB figures and the Fuel page of the FMC don't correspond:
    EFB: ZFW shows 76672 lb whereas the FMC shows 81180 lb -> 118 pax and 4000 lb cargo; empty weight for both applications is 56530 lb.
    Why is there a difference in ZFW? I cannot figure it out.

    Thanks for your help.
