AIRMAN® concept:
e-trouble shooting
The Airbus fly-by-wire aircraft

are all equipped with data record-
ing features such as:
◗ Fault monitoring and diagnostics

undertaken by the Built In Test
Equipment (BITE) of each sys-

◗ ACMS (Aircraft Conditioning
Monitoring System) reports.
All this data can be downloaded

in real time via data-link (ATSU,
ACARS) to the ground. Much of
the information related to mainte-
nance is also available on the
ground, such as:
◗ Aircraft documentation: Trouble

Shooting Manual, Aircraft
Maintenance Manual, etc…)

◗ Airline technical notes
◗ Logbook data
◗ Aircraft delays
◗ Shop data
◗ Airbus information: Service

Information Letter (SIL),
Technical Follow Up (TFU).
By analysing and linking all

maintenance data related to
unscheduled aircraft events,

AIRMAN® provides the following:
◗ Real time aircraft technical follow up
◗ Preventive maintenance actions

(trend monitoring concept)
◗ Analysed maintenance data avail-

able for engineering to optimise
aircraft technical follow up
These features further improve

aircraft dispatch, simplify aircraft
maintenance and cut down mainte-
nance costs.



Step by step approach
The scope of AIRMAN® is large.

The first step has been the develop-
ment of AIRMAN® 2000, which has
been defined with Air France and
Sabena and tested and validated in
the operational environment with
these airlines and JetBlue.

The Airbus objective has been,
and will be, to continuously
involve the airlines in the definition
of AIRMAN® modules. In this
framework, the first "AIRMAN®


The Airbus aircraft technology opens
the door for innovation in the mainte-
nance area. Indeed, the A320 Family
and long range A330/A340 fleet are
all basically equipped with systems
recording maintenance data to be
used by maintenance personnel,
such as ECAM warnings displayed to
the crew, fault messages recorded
by the computers, engines and APU
reports coming from the Data
Management Unit (digital recorder).
All this data can be transmitted in
real time from the aircraft to a
ground station. This data is consid-
ered as high value information relat-
ed to aircraft maintenance.
Use of new electronic data process-
ing (EDP) tools, capable of analysing
this large volume of data coming
from entire fleets, helps the airlines to
manage and anticipate unsched-
uled aircraft events. Their use has
raised high interest in aircraft line

maintenance since non-routine
events are very penalising factors in
daily aircraft operation.
Engine reports directly transmitted
from the aircraft (down-linked) are
already used by many airlines to
monitor their engine parts. In the last
few years, to further improve their line
maintenance and engineering effi-
ciency, they have begun to down-
load ECAM warning and fault mes-
sages. The trend is quite clear that,
due to the advance of technology
on board the aircraft, to further
enhance the maintenance efficien-
cy there is a need for an on-ground
maintenance software aid.
Airbus, in very close cooperation with
selected airline maintenance organi-
sations, and using in-house mainte-
nance expertise, has developed its
own ground based maintenance
software aid: AIRMAN® (AIRcraft
Maintenance ANalysis).

Predictive maintenance

(Hangar maintenance)
Using algorithms based on statisti-
cal analysis, a selected fault mes-
sage from the aircraft is recorded
in the job list and classified as "
new today", "still open" or "long
lasting" item.

This feature allows the mainte-
nance operator to set up the appro-
priate trouble-shooting action
before the failure message leads to
a malfunctioning of a system that
may be reported by the crew in the
logbook. By anticipating mainte-
nance actions, pilot reports (Pireps)
are reduced and thus aircraft
delays. In addition, the mainte-
nance action can be planned
according to the aircraft’s schedule
(see Figure 6).

Data analysis

AIRMAN® 2000 is able to process
the OMS data in order to support
the maintenance teams. The results
come under the form of high value-
added information such as aircraft
failure event concept and fault his-
tory tracking. With this feature, the
operator is able to take the most
appropriate action related to an air-
craft event, saving time and reduc-
ing the cost of “No Fault Found”
(NFF) by providing systematically
"AIRMAN® post flight reports
(PFR)" to justify component


users club" workshop will be set up
during the first half of 2002. This
step-by-step approach allows the
airlines to take the benefit immedi-
ately of features offered by
AIRMAN® 2000 and to define future
modules to meet their needs.

Development of the complete set
of AIRMAN® applications has been
estimated to take four to five years.
Airbus will provide AIRMAN® cus-
tomers with yearly releases. Figure 1
shows an example of future AIR-
MAN® modules that could poten-
tially be connected to AIRMAN®

AIRMAN® 2000

AIRMAN® 2000 provides the fol-
lowing features based on the On-
board Maintenance System (OMS)
data analysis.

Gate maintenance function
Whether the aircraft is at the gate,

on the runway or in flight, the AIR-
MAN® 2000 software gives the
operator direct access from a PC on
the ground (see Figure 2), to infor-
mation on the Current Leg Report
or the Post Flight Report, at any
time (see Figure 3).

AIRMAN® provides centralised
access to information related to an
aircraft event (see Figure 4). Once a
fault message has been analysed,
the AIRMAN® 2000 system pro-
vides the line maintenance operator
with a direct link to the relevant
troubleshooting task in the Trouble
Shooting Manual(see Figure 5).
Furthermore, the operator gets
access to the Airbus Technical
Follow-Up (TFUs) and Service
Information Letter (SIL 00-
028/38/41) and also to any of the
airline selected documentation
such as Technical notes and
Engineering Bulletins.
