FUEL QTY, TEMP, GW AND CG INDICATIONS


 

1
Engine identification number
The engine identification number is amber when the engine is not running, and it is white when the engine is running.
2
Fuel used (per engine)
It is normally green. In case of failure of the fuel flow measurement, the FADEC computes a value of fuel used. Two amber bars appear across the number when this computed value is considered erroneous by more than 136 kg (300 lb). Units may be KG or LB (depending on DMC pin program).
3
Total fuel used
It is normally green. Two amber bars appear across the value when either engine fuel used is crossed. Units may be KG or LB (depending on DMC pin program)
4
Fuel quantity indication
It is normally green. Two amber bars appear across the two last digits when the FQI is inaccurate.In case of fuel unusable (Trim TK or outer TK only), the quantity indication is displayed in amber box. FQI becomes amber in case of low level (inner tank only) or overflow Fuel quantity pulses in inner and outer tanks in the event of imbalance. Units may be KG or LB (depending on DMC pin program)
5
Collector cell fuel quantity indication
It is normally green.Two amber bars appear across the two last digits when the FQI is inaccurate.Units may be KG or LB (depending on DMC pin program)
6
Gross weight indication
It is normally green. Two amber bars appear across the two last digits when the FQI is inaccurate. Units may be KG or LB (depending on DMC pin program). Blue dashes appear when GW is not computed on ground.
7
Center of gravity indication
It is normally green. Comes on red when the FMGC (FE part) detects an, excess aft CG. Blue dashes appear when CG is not computed on ground.
8
Fuel temperature indication
It is normally green. It becomes amber when fuel temperature is :

above 60°C in inner tanks or

below - 37°C in inner tanks or

below - 40°C in outer or trim tanks.
This indication disappears when the tank quantity is below 1000 kg for the trim tank or 1100 kg for the outer tank.
Note : Fuel temperature is not indicated for the right outer tank.
9
Fuel on board quantity
It is normally green. The two last digits are dashed in case of degraded accuracy
Note : In case of any tank fuel partially unusable, the quantity indication is displayed in partial amber box
