MAINTENANCE MANUAL
5. Fuel Quantity Indicator Calibration (S/N’s 4636375 and up.)
(PIR-PPS60226, Rev. NEW.)
A. Setup:
(1) Level the airplane per 8-20-00.
(2) Drain the fuel tanks per 12-10-00, Fuel System, Draining Fuel System - Complete.
B. From the MFD Maintenance page, depress the Line Select Key (L4) to access the Engine Setup
page.
C. Depress the “Fuel Cal” button (L1) to enter Fuel Calibration page.
(4) Depress the “Begin Cal”button (R3) and follow the on-screen calibration procedure for left and
right tank zero fuel (1.0 + .1-0 gal. unusable) and full calibration (60 + 0-1 gal. usable) points.
Wait approximately 3 minutes for fuel level to stabilize.
(5) Use the Right Knob to select the current calibration point. The selected calibration point is
highlighted and the value displayed is the current reported fuel quantity from the DAU. A
message at the bottom of the screen prompts the operator to add the appropriate amount of
fuel and then to select the “Accept Value” button (R3) once the value reported from the DAU
has stabilized.
NOTE: If the DAU reported value is not within 2.5 gallons of the test point value, a message
“DAU reported Fuel Quantity Out of Tolerance” will be presented and the value will not
be accepted.
(6) Once all points have been calibrated, the operator presses “Calibration Complete” to cause the
calibration factors to be computed and applied to the DAU reported fuel quantity.
(7) Other options from the Calibration Underway state are to “Restore Last Cal” and “Clear Cal”.
(a) Pressing “Restore Last Cal” causes the calibration values from the last completed
calibration to be restored and the state to change to Calibrated.
(b) Pressing “Clear Cal” causes all calibration values to be cleared and the state to change to
“Not Calibrated”. An “Are You Sure?” prompt will give the operator a chance to reconsider
the decision to either “Restore Last Cal” or “Clear Cal”.
(8) When the calibration procedure has been completed, press the Save button. If you decide not
to save the changes, pressing the Cancel button from the Underway state causes the current
calibration session to be aborted with any unsaved interim calibration values being discarded.
Changed will not take effect until the MFD has been restarted.
NOTE: The “empty” and “full” fuel readings on this setup page will NOT display zero (0) or 60
gallons usable fuel for respective empty and full calibration points. However, the
appropriate zero and full (60 U.S. gallons) will be displayed on the MFD in normal
operation mode (not maintenance setup.)
(9) Verify DAU Status Box reads: DAU(s) configured for Piper PA-46-350P (Mirage).
(10) Verify Calibration Status Box reads:
“Left Fuel Tank: Calibrated”
“Right Fuel Tank: Calibrated”
