VIBRATION SENSING
EVMU operation.
The normal mode of operation allows the system to:
-Display the vibration information on the ECAM.
-Provide fault information when advisory levels are
reached, or exceeded.
-Provide flight recordings.
Vibration recordings are made at five different engine speeds to provide information for fan trim balance procedures and frequency analysis.
They are also transmitted to the AIDS system to be included in the printing of all the reports, such as cruise, or take-off.
