Indication
c) Both FMC’s operate normally. EICAS STATUS MESSAGES
None
PLACARD
Fuel Quantity Indicator - TOTAL FUEL QUANTITY INOP
MAINTENANCE NOTE
Operational Program Software part number is shown on the FMC IDENT page. OPERATIONS (O)
1. Total fuel quantity must be calculated and manually initialized on the FMC Performance Initialization Page prior to engine start.
2. If total fuel quantity is inoperative as a result of an individual tank quantity indication, MEL restrictions for that item must be observed.
3. Prior to each engine start, confirm that fuel flow system inputs are valid on the FMC SENSOR STATUS Page 1 (Left and Right EICAS OK) or (Left and Right FUEL FLO OK).
4. (Optional) Prior to each engine shutdown, record FMC CALCULATED FUEL QTY. For flights not requiring additional fuel, this value may be used as a means of determining total fuel quantity.
5. In case of enroute failure of the FMC calculated total fuel quantity, flight crew must keep a fuel log for the remainder of the flight.
NOTE 1: The PROGRESS page 1 display of FUEL quantity and ATA at the last waypoint prior to failure may be used as a starting point. In some failure modes, PROGRESS page 2 FUEL USED data may be available.
NOTE 2: Aileron trim indication on the control wheel may be used to determine if a fuel imbalance condition exists. At cruise conditions, an imbalance of 725 kg will require approximately one unit of aileron trim to hold wings level.
