H.4.3.3 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. ADAHRS Unit Orientation (Appendix H.4.3.1
) and
Pitch/Roll Offset Compensation (Appendix H.4.3.2
) are required before 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. Enter configuration mode by holding down the left-hand softkey while powering on the PFD 1
display (if needed).
2. Use the FMS Joystick to select the ADAHRS Page (if needed).
3. Make sure that all the required status boxes are checked (Table H-2
and Table H-3). Use the FMS
Joystick to select which ADAHRS (1, 2 or 3) is being configured.
