VIBRATION SENSING
Sensing system introduction.
The engine vibration sensing system enables the crew to monitor engine vibration on the ECAM system, and also provides maintenance staff with the following:
-Vibration indication.
-Excess vibration (above advisory levels).
-Storage of balancing data.
- Bite and MCDU communication with other A/C
systems.
-Accelerometer selection.
-Frequency analysis for component vibration search

Engine/aircraft vibration systems.
The engine/aircraft vibration sensing system is made up of the following devices:
-The engine sensors. -The Engine Vibration Monitoring Unit (EVMU), which interfaces with engine and aircraft systems.
Vibration information is provided to the following:
-The ECAM system, for real time monitoring. -The CFDS (Centralized Fault Display System). -The AIDS (Aircraft Integrated Data System).
The CFDS system is used to:
-Recall and print previous leg events. -Initiate tests. -Reconfigure engine sensors.
The AIDS system is used to perform:
-Troubleshooting. -Condition monitoring.
