(3) Case 2: In case of degraded data (if indication of fuel flow is not valid in flight after 60s) , all the digits are dashed with two horizontal amber lines (fuel flow value from the FADEC bus not correctly received by the DMC in flight).

(4) Case 3: It is replaced by amber XX after a long DMC power supply interruption in flight. In this case, the fuel used computation stops untill next starting sequence on ground. As a result, the total fuel used is also replaced by two amber XX.

M. Item 10 - Engine number
The number of each engine is normally white. It is amber when the engine is stopped (core speed not at idle or not above idle).

N. Item 11 - Total Fuel Used
A total fuel used is computed
-and normally displayed in green (case 1).
-
As soon as one (at least) of the two fuel used values is dashed (degraded data), then the total fuel used is also dashed (case 2)
-
As soon as one (at least) of the two fuel used values is replaced by amber XX, then the total fuel used is also replaced by amber XX (case 3).
The digital value can vary from 0 to 99,990 KG by 10 KG steps.

(1)
Case 1:
It is normally displayed in green.
(2)
Case 2: In case of degraded data (indication from FQI), the two least significant digits are set to zero with amber lines across.
(3)
Case 3: The value displayed is replaced by amber XX, when no valid data are available from the FQI bus.
(4)
Case 4: The digital value is displayed in an amber box as soon as one of the two wing transfer valves is faulty.
