WEIGHT/CG.........................................................................................................................INTIALIZE
L2 In flight, after a dual FCMC reset, the weight (GW) and CG displayed on the FUEL PRED page are
those computed by the FE. However, the GW computed by the FE may be less accurate, therefore:
If the FCMC reset is successful, the FCMC 1+2 FAULT ECAM ‐ caution will be replaced by the
NO WEIGHT/CG DATA ECAM caution. Refer to this caution for the GW and CG re-initialization
procedure.
‐ If the FCMC reset is not successful, determine the Fuel on Board (FOB) from the engine start
fuel quantity minus the Fuel Used (FU) quantity indication.
