Adjusting the fuel totalizer quantity:

Resetting the fuel totalizer:
On the Engine System Page, press the RST Fuel Softkey; this resets displayed fuel remaining (GAL REM) to the
maximum fuel capacity for the aircraft and fuel used to zero.
A map feature related to the EIS Fuel Calculations is the Fuel Range Ring, which graphically illustrates the
aircraft' s remaining range based on heading, groundspeed, and wind direction and speed. The solid green circle
represents the range until all the remaining fuel is depleted. The dashed green circle indicates the aircraft range
until only reserve fuel remains. Once on reserve fuel, the range is indicated by a solid amber circle.
The Fuel Range Ring shifts position in relation to the aircraft according to wind effects. For example, more
fuel is required for flying into a headwind, and the aircraft' s decreased range in that direction is indicated by the
Fuel Range Ring shifting toward the tail of the Aircraft Symbol.
The amount of reserve fuel (only for purposes of the Fuel Range Ring) is set on the Navigation Map Page
Setup Menu in terms of remaining flight time. When enabled the Fuel Range Ring appears on the Navigation
Map Page, the Weather Data Link Page, and PFD Inset Map.
Enabling/disabling the Fuel Range Ring and selecting a reserve fuel time:
1) Display the Navigation Map Page (press and hold the CLR Key for 2 seconds to quickly select this map).
2) Press the MENU Key.
3) Highlight 'Map Settings' and press the ENT Key. The Map Settings Menu is displayed.
4) Use the small FMS Knob to select the 'Map' group and press the ENT Key.
5) Highlight the 'Fuel Range (RSV)' field.
6) Turn the small FMS Knob to select 'On' or 'Off'.
7) Turn the large FMS Knob to highlight the reserve fuel time, how long the aircraft can fly after reaching the
reserve fuel.
