Engine Run-Up Vibration Test
NOTE
The Engine Run-Up Vibration Test is required for all installations to validate the vibration
characteristics of the installation. The ADAHRS Unit Orientation (
) and
Pitch/Roll Offset Compensation (
) are not required prior to this
procedure.
NOTE
Passing the Engine Run-Up Vibration test does not remove the requirement to rigidly
mount the GSU 25/GSU 73 to the aircraft primary structure. The Engine Run-Up
Vibration Test is intended to help discover mounting issues but successful completion of
the test does not validate the mounting of the GSU and GMU, and does not account for all
possible vibration profiles that may be encountered during normal aircraft operation.
1. Power on PFD1 in configuration mode (
), this step can be skipped if PFD1 is already
in configuration mode.
2. Use the Touch Panel or a Move Selector Knob to select the ADAHRS Calibration Page.
3. Ensure that all the required status boxes are checked (
). Use the Touch
Panel or a Move Selector Knob to select the ADAHRS (1, 2 or 3) that is being configured.
4. Use the Touch Panel or a Move Selector Knob to select Engine Run-up Test.
