LAY08521 - L1502T0 - LM45Z1OMS000001
The Onboard Maintenance System (OMS) is designed to support line
and hangar maintenance activities, and engineering follow-up.
The OMS is mainly composed of three sub-systems:
- The Central Maintenance System (CMS)
- The Data Loading and Configuration System (DLCS)
- The Aircraft Condition Monitoring System (ACMS)

General
LAY08521 - L1502T0 - LM45P1CMS000001
The Central Maintenance System (CMS) is part of the Onboard
Maintenance System (OMS), hosted in Network Server System (NSS),
in the Open World. The CMS is a system devoted to the centralization
of operational and maintenance data related to both Avionics and some
Network Server Systems (NSS) failures. Note that the CMS receives this
data from Avionics systems through the Secure Communication Interfaces
(SCIs), and directly from Open World systems. The CMS can be operated
through several NSS Human Machine Interfaces (HMIs).
It can also exchange data with airlines operational centers through service
providers either automatically in case of failure detection or on request
for maintenance issues.

CMS Functions
LAY08521 - L1502T0 - LM45P1CMS000001
The CMS operates in two modes, a normal mode and an interactive mode.
The functions done in normal mode are, the:
- systems continuous monitoring,
- failure, identification and correlation
- centralization of failures events and parameters sent by the BITEs
- report generation
The interactive mode basically enables:
- access to eLogbook, AirN@V and MEL
- interactive system tests
- access to system monitoring
- access to maintenance history
The interactive mode only operates on ground, and always requires an
operator action.
Note that all the A/C systems, which have an internal BITE function, are
monitored by the CMS.

CMS Architecture
Aircraft systems are monitored by:
- The CMS Application which is part of the Avionics Domain
- Right CMS Applications hosted in the Flight Ops and Cabin Domain
The CMS Application, hosted in an Open World server, acquires through
the SCIs two different types of data from the Avionics World Systems:
- Maintenance Data: Systems BITEs
- Operational Data: Warnings and flight phases from the Flight Warning
System (FWS), flags and advisories from the Control and Display System
(CDS), and e-logbook defects entered either by the pilots or by the cabin
crew
Note that these servers also contain other applications dedicated to
facilitate maintenance activities (AirN@v, eLogbook), and also database
to store all maintenance parameters acquired from the Avionics World.
The HMIs, which are used to control the CMS, are:
- The CAPT and F/O Onboard Information Terminals (OITs) and their
related keyboards
- The Onboard Maintenance Terminal (OMT)
- The Portable Multipurpose Access Terminal (PMAT)
- The Printer 1 (for maintenance reports)
Both OMS and Right-OMS are hosted in the Open World in the Network
Server System (NSS) servers and components, but they have their own
specificities:
- the OMS functions monitor and centralize failures of systems part of
the Avionics World and the Avionics Domain (NSS) only
- the R-OMS functions monitor and manage failure of systems connected
to the right side of the Open World Diode (OWD)
Note that the CMS and Right OMS can communicate with the operational
ground centers and service providers in order to enable maintenance data
exchanges.

AIRCRAFT CONDITION MONITORING SYSTEM PRESENTATION (1)
General
LAY08521 - L1502T0 - LM45P3ACMS00001
The Aircraft Condition Monitoring System (ACMS) is part of the Onboard
Maintenance System (OMS), hosted in Network Server System (NSS),
in the Open World. The aim of the ACMS is to acquire and process A/C
operational data in order to get easier preventive maintenance.
Note that the ACMS receives this data from Avionics systems through
the Centralized Data Acquisition Module (CDAM).
It is also used during troubleshooting procedures, to do in-depth
investigations.
The ACMS can be operated through several NSS Human Machine
Interfaces (HMIs).
It can also communicate with airline operational ground centers through
service providers for the exchange of maintenance data upon airline
requests.

ACMS Functions
LAY08521 - L1502T0 - LM45P3ACMS00001
The ACMS has been designed to achieve four main functions:
- A/C systems condition monitoring
- Data recording
- Real-Time monitoring
- Data acquisition for NSS Application
First the ACMS does a permanent A/C systems monitoring to improve
the A/C maintenance efficiency, to reduce repairing times and to decrease
maintenance costs. To do that, the ACMS:
- Acquires A/C systems parameters
- Manages the storage of these parameters
- Does in real-time systems parameters monitoring
- Processes system reports of parameters, which can be used for trend
monitoring.
The ACMS is a help to do in-depth troubleshooting procedures in order
to get easier resolution of technical investigation.
Finally the ACMS is used for the data acquisition and transmission of
selected parameters to OPEN WORLD Applications (Ex: MOVING
MAP).

ACMS Architecture
The ACMS is mainly composed of a software application hosted in the
Avionics Domain, which is part of the NSS.
The ACMS, hosted in an Open World server, acquires data from the
LRUs and LRMs located in the Avionics World, through the Centralized
Data Acquisition Module (CDAM). Then this data is stored in a dedicated
maintenance database hosted in the servers, and is used to generate reports
or to enable Real-time parameters display. The server also contains other
applications dedicated to make easier maintenance activities (AirN@v,
eLogbook).
The data acquired by the CDAM can also be stored in an optional Digital
ACMS Recorder (DAR) depending on the airline request.
Note that the communication from the NSS to the CDAM, is made
through the Secure Communication Interfaces (SCIs).
The HMIs which are used to control the ACMS are:
- The CAPT and F/O Onboard Information Terminals (OITs) and their
related keyboards
- The Onboard Maintenance Terminal (OMT)
- The Portable Multipurpose Access Terminal (PMAT) which is a Ground
Support Equipment (GSE)
- The Printer 1 (for maintenance reports)
Note that ACMS can communicate with the airline operational ground
centers and service providers in order to enable maintenance data
exchanges.

OMS Safety Items
LAY08521 - L1502T0 - LM45P4MAIN00001
When you work with the Onboard Maintenance System (OMS), make
sure that you obey all the AMM safety precautions. This will prevent to
injury persons and/or damage the aircraft. Here is an overview of main
safety precautions relative to the OMS.
When you are operating the OMS, and particularly when you perform
interactive system tests, you have to be aware that the powerplant systems
can be activated and that some mechanical parts can move.
Before any maintenance operations, make sure that all the safety devices
and all the warning notices are in position.
For more detailed information, refer to the safety precautions
recommended in the maintenance procedures associated to each aircraft
systems.

The OMS tasks require some Ground Support Equipment (GSE).
An example of GSE used for OMS activities is the Standalone
Identification System (SIS) tool.
This tool, which must be connected directly to the computers, is used to
access to the computer identification in terms of equipment and software
part numbers. Refer to the illustrated Tool and Equipment Manual (TEM)
for the complete list of the tools.
