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.
