Fuel Quantity Calibration (Optional)
Fuel quantity indicator calibration is used to compensate for aircraft-to-aircraft variations in the fuel
quantities reported by the Engine Data Acquisition Unit (DAU). If available, select the
Fuel Cal button d
from the Engine Instruments Setup Page.
➥
When upgrading an MFD, be sure to use the Configuration Save and Restore Utility instead of
recalibrating the fuel quantity. See Section 5.3, “Using the Configuration Save and Restore (CSR)
Utility” on page 32 for more information.
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,
530-00195-002, 530-00195-012, and 530-00201-002.
➥
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-(), and
530-00201-() 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.
