Note:
This option is not available on all aircraft. This option is only available with software part
numbers 530-00137-000, 530-00137-001, 530-00170-000, 530-00170-002, 530-00180-002, ,
530-00201-002 and 053-00235-002.
The fuel quantity indicator can only be calibrated if the DAU is communicating with the MFD and
sending valid fuel quantity data. If the DAU is not communicating with the MFD, a DAU failure screen
is displayed when the Fuel Cal Page is selected. In this case, the only available selection is to exit the
page.
The Fuel Quantity Indicator Calibration Page displays the current fuel quantity indicator calibration
values. Different options are available depending on the state of the fuel quantity indicator calibration.
The three states of the fuel quantity indicator calibration are:
1.
Not Calibrated
2.
Calibration Underway
3.
Calibrated
To calibrate fuel quantity for 530-00137-() and most 530-00170-(), 530-00180-(), 530-00195-(), 530-
00201-(), and 053-00235-() software:
1.
From the Engine Instruments Setup Page, select
Fuel Cal
.
2.
From the Not Calibrated state, select
Begin Cal
.
•
The state of fuel calibration changes to Underway and the fuel quantity indicator can be
calibrated.
•
If you press
Exit
, the Engine Instruments Setup Page displays with the calibration state
unchanged.
3.
Use the right knob to select the current calibration point. The selected calibration point is
highlighted and the value displayed is the current reported quantity from the DAU. A message at
the bottom of the screen prompts you to add the appropriate amount of fuel. Then press
Accept
Value
once the value reported from the DAU has stabilized.
If the DAU reported value is not within 2 gallons of the test point value, the value is not accepted
and the message “DAU Reported Fuel Quantity Out Of Tolerance” is displayed. Recalibrate the
current calibration point.
If you cannot correctly calibrate the fuel quantity, inspect the fuel tank and fuel level sensor for
problems.
4.
Repeat this process for all the calibration points.
5.
To pause the calibration process and turn off power to the MFD, press
Save
to save the interim
calibration values.
6.
Once all points have been calibrated, press
Calibration Complete
. The calibration factors are
computed and applied to DAU reported fuel quantity.
7.
When you are done, press
Save
. Press
Cancel
to exit without saving changes.
8.
Changes do not take effect until the MFD has been restarted. From the Maintenance Mode Page,
press
Restart System
.
Other options from the Underway state are to
Restore Last Cal
and
Clear Cal
:
•
Press
Restore Last Cal
to restore the calibration values from the last completed calibration. The
calibration state is change to Calibrated.
•
Press
Clear Cal
to clear all calibration values. The state changes to Not Calibrated.
An
Are You Sure?
prompt gives you the chance to reconsider the decision to either restore or clear
the fuel calculations.
