Fuel Consumption - AvMap GeoPilot II PLUS User Manual

10.6 fUel ConSUmPTIon

The Geopilot II Plus computes Fuel Consumption for each leg of the active Flight Plan or the
fuel used in flight, based on entries made by the pilot. This is a useful feature for flight planning
purposes. Actual Fuel Consumption will vary based on flight conditions and engine settings.
Fuel can be calculated in pounds, liters or gallons; the units of measure used for the valuesentered
here are selected from Units Setup menu in the System Setup Menu (see Par. 14.5).
> 'MENU' 1 sec. + "CALCULATOR" + 'ENT' + "FUEL CONSUMPTION" + 'ENT'
Fig. 10.6 - Fuel Consumption page
To set Fuel Consumption parameters use 'ENT' to edit the selected field (a box appears around the
active field) and use the cursor key to move between fields. Press 'ESC' to return to the Calculator
Menu. If your current Ground Speed is over 20 Knots, the Geopilot II Plus will display "Actual GS"
and will not allow you to edit the value.
The Geopilot II Plus will compute and display Fuel Consumption for each leg of a Flight Plan, and
total fuel needed for the flight in the Flight Plan page (see Chapter 6). When selected for display,
the data fields window will provide information on the flight time remaining before the reserve fuel
has been reached.
Note
The Fuel Consumption represents calculated fuel use based on user data. The reserve does not represent actual
fuel available in the aircraft.
Fuel Consumption can be modified en route by increasing or decreasing the fuel burn rate to match
actual usage. The new fuel computation will be averaged over the full distance and provide a good
estimate of fuel remaining. When refueling en route, combine the amount of new fuel and the
remaining fuel to enter the new "Starting Fuel" total for true computation of To Reserve data.
Note
Fuel calculations are only as accurate as the entries made. Always double-check fuel calculations.
