processed, and transmitted to the Engine Indicating System for
display.
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
gage 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.
