Engine Indication System
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 wind ef-
fects. 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 Setttings' 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 RNG (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.
8) Enter the desired reserve fuel time (00:00 to 23:59; hours:minutes) and
press the ENT Key.
9) Press the FMS Knob to return to the Navigation Map Page.
