It slowly starting making some sense:)
Normally the BLOCK fuel is already there. Then we enter ZFW/ZFWCG and finally get the message.

Microburst2002:

I also see only fuel traces in this story. In particular the message often comes when there was no fuel taken on turnaround, i.e. fuel distribution may be not standard.

TyroPicard:

Still I don't see any sense. The data entered into each FMGEC is identical. Why should it in turn supply FCMC with different data and not once in a while but quite often? What kind of...

This message comes too often to be a failure. And, BTW, there is a NORMAL SOP for that case:
"‐ Check the loadsheet CG, against the ECAM CG. In case there is a discrepancy of more than 2 %, check...

The data in both FMGECs is synchronized. They don't compute the CG/ZWF initial data. It's a pure mechanical entry and there is no reason for them to be different like any other pilot input. Yet the...

A33Zab:

Nice diagramm, but it's not answering the post question. FCMC takes over CG calculation only after initial ZFCG and ZFW entered by pilots. It does't have anything to compare these values...

Did you notice if the message is showing after you inserted the fuel figure but the fuel is not yet on board ?

Have you already entered a "planned" ZFW ? If so , i think it is just questioning why you have changed this again as you enter the actual value from the loadsheet.

Nope. We don't...

With each other.
Confirm that the ZFW and ZFCG values from each FMGC are the same as the loadsheet value.
Maybe the figures inserted through one MCDU are different from the one previously inserted...

Well, we clear it, we reinsert it - no problem:) But, the question remains: what data does the FCMC compare with inserted data? How does the aicraft know what is right or wrong???

A330 ZFW/ZFCG DISAGREE

Could someone enlighten me, what this ECAM message means?
Ok, FCOM says: "One FCMC detects that the ZFW or ZFCG data from FMGEC 1 and FMGEC 2 disagree". Still doesn't make much sense to me....
