Adjusting the fuel totalizer quantity:
1) On the MFD, press the Engine Softkey.
2) Press the System softkey.
3) Press the GAL REM softkey.
Select the softkey that best describes the current fuel load desired. Once selected, press the BACK softkey.
Resetting the fuel totalizer:
Press the RST Fuel Softkey; this resets displayed fuel remaining (GAL REM) 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 current calculated 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 the current calculated 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. However, it
does not calculate forecasted winds and weather from the datalink.
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'.
