Fuel Planning

Fuel Planning — When equipped with fuel flow (FF) and/or fuel on
board (FOB) sensors, this item displays fuel conditions along the active
direct-to or flight plan. You may also manually enter fuel flow, ground
speed (GS) and (in some instances) fuel on board figures for planning
purposes. Fuel planning figures can be displayed not only for the currently
active flight plan or direct-to, but also point-to-point between two specified
waypoints and for any programmed flight plan. Fuel planning figures can
be entered and displayed based upon one of three configurations:
• No Fuel Sensors Connected — In this instance fuel on board and fuel flow
are manually entered in the unit start-up sequence and used to recalculate
fuel on board as it is consumed. When fuel flow or fuel on board is manually
entered, the figures are retained the next time you view the page (with fuel
on board continuously recalculated).
• Fuel Flow Sensor Installed, But No Fuel On Board Sensor — Fuel on board is
manually entered. Fuel flow is automatically provided by sensor. If fuel flow
is manually entered (to override the sensor), it does not affect the FOB figure
and is not retained the next time you view the page.
• Fuel Flow and Fuel On Board Sensors Installed — Fuel flow and fuel on
board are automatically provided by sensors. Fuel on board can NOT be
entered manually. Fuel Flow can be entered manually, but does not affect the
FOB figure and is not retained the next time you view the page.
