Fuel Totalizer and Calculated Information
Fuel totalizer calculations are located in the lower right section of the
ENGINE page and are separate and independent of the fuel quantity gauge
and float sensor system. The fuel totalizer monitors fuel flow and calculates
fuel-to-destination, fuel used, fuel remaining, time remaining, fuel range,
and nautical miles per gallon. Upon system startup, the fuel totalizer initial
fuel screen appears and prompts the user to enter the total fuel on board at
start. The option to enter the number of gallons added since last fuel fill and
the ability to set fuel to "Full" or to "Tabs" buttons is also available.
Fuel System Annunciations
Fuel system health, caution, and warning messages are displayed in
color-coded text in the Crew Alerting System (CAS) window located to the
right of the Altimeter and Vertical Speed Indicator. In combination with a
CAS alert, the affected fuel parameter displayed on the ENGINE page
changes to the corresponding color of CAS alert and the annunciation
system issues an audio alert.
FUEL QTY: Fuel quantity.
• A white Advisory message is generated when either fuel tank goes
below 14 gallons.
• An amber Caution message is generated when both fuel tanks go below
14 gallons.
• A red Warning message is generated when the fuel totalizer or sensed
fuel quantity (left plus right) is below 9 gallons.
FUEL IMBALANCE: Imbalanced between Left and Right Tanks.
• A white Advisory message is generated when the imbalance between
tanks is greater than 8 gallons.
• An amber Caution message is generated when the imbalance between
tanks is greater than 10 gallons.
• A red Warning message is generated when the imbalance between
tanks is greater than 12 gallons.
For specific pilot actions in response to Fuel System Annuncia-
tions, refer to Section 3 - Emergency Procedures,
Emergencies, and Section 3A - Abnormal Procedures,
