4.3. Weights
FMS1/FMS2 GW DIFF
This scratchpad message (white) is displayed when the difference is
less than or equal to 1,5 metric tons.
This should be due to a sensor anomaly.
CHECK GW
When A/C is airborne, the FMS GW value
(FUEL PRED page) is continuously cross-
checked with the A/C GW value computed
by the FAC when available.
If these weights differ by more than 7 tons
(16055 Lbs), CHECK GW scratchpad
message (amber) is displayed.
Check for wrong pilot entry.
GW may be overwritten on FUEL PRED
page.
