INTRODUCTION
The F2000EX EASy system enables the flight or maintenance crew to:
- obtain airplane system failure information requested for an optimized and safe dispatch
decision,
- print or download maintenance reports,
- upload navigation files and data bases,
- obtain airplane failure and status information, perform additional ground tests, as
requested for servicing, maintenance and troubleshooting operations.
The above listed capabilities rely on the F2000EX EASy Airplane Diagnostic and Maintenance
System (ADMS) which includes first:
- the built-in test functions of the avionics, Head-up Guidance System (HGS), engine and
airplane systems, which enable these systems to:
o detect and report failures to the EASy system in real time, in flight or on ground,
o perform on-ground additional tests on request,
- the EASy functions in charge of elaborating and displaying failure information for dispatch
decision,
- the EASy Central Maintenance Computer Function (CMCF).

ELABORATION AND DISPLAY OF FAILURE INFORMATION FOR DISPATCH DECISION
The EASy avionics system (Monitor Warning and Graphic Generation functions) processes
the EASy input data, and, when a failure is detected, generates the proper cockpit indication
for dispatch decision. This indication consists of one or several CAS messages, as well as
abnormal status indication presented on PDU (gears, slats / flaps, airbrakes, …).
When recommended by the Master Minimum Equipment List (MMEL), and in order to limit as
much as possible dispatch restriction, detailed failure information can be obtained in the
systems, STAT and TEST synoptics, or by a direct computer fault code readout performed on
ground with the Fault Code Display (FCD) device.
CENTRAL MAINTENANCE COMPUTER FUNCTION
The EASy Central Maintenance Computer Function (CMCF) provides:
- a single access to avionics, HGS, engines and airplane systems maintenance
messages, status information and initiated ground tests, requested for servicing,
maintenance and troubleshooting purposes,
- a means of loading navigation files and data bases, and system software from the on-
board Data Management Unit (DMU) located in the cockpit (LH console), or from a
laptop acting as a Centralized Maintenance Computer (CMC) Remote Terminal
(CMC RT),
- a means of downloading maintenance data to the on-board DMU, or to a laptop acting
as a CMC RT,
- a means of printing data on the optional on-board printer located in the cockpit (RH
console),
- a means of configuring the maintenance computer RS-232 port located in the cockpit
maintenance panel, in order to connect the FCD device to one of the following airplane
system computers:
o Engine Diagnostic Units (EDU) 1 and 2,
o Cabin Pressure Control (CPC),
o Bleed Air Supply Computer (BASC) control and monitoring,
o Fuel Quantity Management Computer (FQMC) channels 1 and 2,
o Braking and Steering Control Units (BSCU) 1 and 2,
o Temperature Control System (TCS crew, TCS pax, TCS man) of the air conditioning
computer.

The CMCF is hosted by the CMC module. It can be controlled:
- from the cockpit, on ground, with the Cursor Control Device (CCD) to navigate in the
menu of the CMC maintenance window displayed on one MDU,
- from a standard laptop connected to the EASy Local Area Network (LAN) connector
located in the maintenance panel (with the LAN adapter connected into the
MAINTENANCE OPERATION plug), and configured as a CMC RT by executing the
dedicated software. The CMC RT can be used with the airplane being either on ground
or in flight.
In this document, the CMC cockpit control mode will be the mode mainly described. For more
information related to the CMC RT mode, refer to the Aircraft Maintenance Manual / ATA 45.
NOTE
The CMCF software does not comply with certification requirements applicable to functions
generating and displaying information related to the safety of flights, as the Monitor Warning
and Graphics Generation functions do. Consequently, failure and status information displayed
on the CMC maintenance window cannot be considered as the only information used for
dispatch decision: they are dedicated to servicing, maintenance and troubleshooting purposes.

ELECTRICAL
The Centralized Maintenance Computer (CMC) is a module of a Modular Avionics Unit
(MAU). It is installed in slot 2 of MAU 2 (MAU 2 is installed in the airplane nose cone). It is
powered by channel A line through RH B2 bus when the RH AV MASTER switch is
depressed, and is protected by the MAU 2 CH A circuit breaker.
The CMC is consequently not powered in MINI LOAD mode.
The CMC is alternately powered by the LH DU stand-by battery during avionics or airplane
power-off in order to ensure a proper CMC shutdown.

DATA
The data available for processing and display of failure information requested for dispatch
decision, and for the Central Maintenance Computer Function are all analog, discrete and
digital data available to the avionics system. These include:
- all information received by the MAU(s) for flight management,
- faults reported in real time by the system computers (avionics, HGS, engines, airplane
systems), on ground or in flight, through digital links (ARINC 429 or ASCB),
- fault reports automatically downloaded on ground from air conditioning computer which
is not capable of sending its fault reports in real-time to the CMC.

ACCESS TO THE MAINTENANCE WINDOW ON MDU
The CMC maintenance window can be displayed on the upper or lower MDU, or on the right
PDU if configured as an MDU. It can be displayed as follows:
- put the CCD cursor in any 1/3 or 2/3 window of the selected MDU,
- call the menu by depressing the CCD MENU button,
- select the MAINT item of the menu. The CMC maintenance window will appear on the
MDU as a 2/3 window.
