4.3 “Add Fuel” Screen:
The Add Fuel screen allows you to update the “Fuel Remaining” as
displayed in the “Fuel Management” screen. The Fuel Remaining is
calculated from fuel flow. The following data fields are provided in
this screen:
Fuel Added: This field should be used when fuel has been
added but the tank has not been filled. Enter the amount of
fuel added to the tank. The “Fuel Rem” then will be updated
and displayed automatically.
Fuel Rem.: Use this field to set a specific quantity of fuel
remaining in the aircraft. The fuel remaining should be equal
to the sum of all the fuel in all the fuel tanks.
“Set to Default 1” and “Set to Default 2:” These two
fields allow you to quickly set the “Fuel Rem.” to one of two default levels. The default levels may be set up at
the bottom of this screen.
Undo Fuel Chages: This field allows you to undo all changes that were made since the time you entered this
screen.
“K Factor Adjustment” Section:
If after filling the fuel tanks you find an error in the fuel “Calc’d Used Since Fill up” (as shown on the screen)
when compared to the actual fuel used (as read off the fuel pump), you can manually or automatically adjust
the K Factor. The K Factor is a measurement of the pulses per gallon that the flow transducer outputs. Due
to variations in the installation of the flow transducer, it may be necessary to adjust the K Factor for the first
few flights in order to get an accurate fuel remaining, fuel used and flow reading.
The K Factor should be changed only when the fuel tanks have been filled accurately on level ground. After a
few adjustments of the K Factor, the fuel remaining and the fuel used as calculated by the MVP should be
within a few gallons (or less) of actual and should not need further adjustment. Use the following fields, as
necessary, to correct the K Factor.
Calc’d Used Since Fill up: This field displays how much fuel the MVP calculated you used since the last fill
up, based on the current K Factor.
Actual (Pump Reading): If there is an error in the calculated Fuel Used, enter the actual fuel used (pump
reading) in this field to correct the K Factor.
Percentage Error: This field displays the percentage of difference between “Calc’d Used Since Fill up” and
“Actual (Pump Reading)” fields. Large % errors may be an indication that you did something wrong.
Auto Adjust K Factor?: Selecting this option will allow the MVP to automatically correct the K Factor
based on the data entered in the fields above.
