6.3.7.1 CALIBRATION PROCEDURE A: PITCH/ROLL OFFSET
COMPENSATION
NOTE
The G5(s) must be installed within the tolerances shown in
NOTE
If two G5's are installed, this procedure must be done on both and can be done
concurrently.
See Section 6.3.7.1.1 for example of this calibration procedure.
Using the following procedure, complete these equations.
1. *Consult the aircraft's maintenance manual and locate the longitudinal (ROLL) and
lateral (PITCH) leveling points.
2. Using a digital level, document the Aircraft Roll and Pitch offsets from these leveling
points as the aircraft sits on the landing gear. (Do not enter, exit, or move the aircraft at
this point.) Use a negative number for left wing up or nose up readings. Use a positive
number for left wing down or nose down readings.
3. Select the Attitude Configuration Page.
4. Select Calibrate Pitch/Roll.
5. Ensure that aircraft and the unit comply with all on-screen instructions then select Start.
-Disregard item 1, leveling the aircraft is not necessary.
6. A progress screen will then be displayed. There is a 30 second countdown timer for the
procedure that resets if the aircraft moves.
7. When the calibration is complete, a successful status message will be displayed along
with the new pitch and roll offsets.
8. If the leveling offsets documented from Step 2 were both 0.0, the calibration is
complete. If either new offset were other than 0.0, continue to step 9.
9. Document the "New Roll Offset" and "New Pitch Offset" numbers and complete the
equation.
10. Press "Done" and adjust the values of the "Roll Calibration" and the "Pitch
Calibration" values to the answers from the equations.
11. Exit Configuration Mode.
12. This completes the Attitude Calibration Procedure.
*In flight level cruse attitude is not necessarily the same as the leveling points provided by the
manufacturer. Adjustments to the pitch and roll offsets can be made to compensate for the
aircraft flight characteristics.
