AFDM
V 1.1
(Assisted Flight Data Monitoring)
An efficient and economic solution to the problem
of Flight Monitoring.
• Regulatory requirements
– ICAO Annex 6, paragraph 1 amendment 26
– JAR OPS 1.035 & 1.037
– FAA FOQA
• The level of processing of the recorded information is not specified
A wide variety of solutions is available:
From simple grids of 12 to 20 parameters up to complete flight
reconstruction and automated risk analysis.

AFDM: Main Constraints of a Flight Monitoring System
V 1.1
• Systematic recovery of all the flight data
• Acquisition of processing software
• Establishing a team of specialists able to run the software and to remedy
typical deficiencies of flight recorders
 Transient interruptions
 Electrical interferences
 Invalid parameters
 Recording media faults

ATS INTERNATIONAL
AFDM: Specifics of the solution proposed by ATS International
V 1.1
– Uses the most powerful software available in the market under an Airbus
agreement.
 Today AIRBUS LOMS (stands for Line Operation Monitoring System)
 Tomorrow AIRBUS AIRFASE
– No long term financial or human investment to add to the function of the
Flight Safety Officer
 No need to buy software
 No need to create a supplementary team of specialists
The FSO must only receive additional training which is not time consuming,
thanks to the tool’s user-friendliness.

AFDM: available Functions
V 1.1
– Rapid and automatic processing of all flights:
Analysis: 4 seconds per flight
In average, 80 % of flights accessible
– Automatic detection of operating anomalies:
Detection of events, sorted by date and with 3 levels of severity.
– Data compression to allow flight reconstruction under an acceptable file
volume (LOM files).Uneventful segments of cruise are eliminated.
– Means of flight visualization allowing rapid analysis, by pilots with no
previous experience of interpreting recordings traces
– Means of processing statistics to rapidly access significant events and to
observe their development over time (reports)

ATS INTERNATIONAL
AFDM:Objectives
V 1.1
– Once the shortcomings of recorders outputs are eliminated (technical
validation), LOMS allows a very thorough and accurate monitoring of
operational reality.
– After analysis, with pilots co-operation (without any temptation for punitive
action and with absolute confidentiality) LOMS permits the identification of
actual risks and initiation of corrective measures BEFORE these precursors
can develop into an accident.

AFDM: Practical Operations
V 1.1
– The company regularly sends to ATS all the raw data recorded
– ATS performs the technical validation and returns the compressed data
(LOM file), which is directly interpretable by the companies’ FSO, through
the visualization means installed by ATS
– The exchange of data can be achieved :
 Either by exchange of disks
 Or by file transmission over the internet
– The FSO can thus, carry out the analysis, collect the pilots comments and
« de-identify » the data base.He has the tools available for visualization and
production of « reports ». He is the sole administrator of the data base which
he has operationally filtered
Note: The operational validation consists of filtering / eliminating events
according to specific operating conditions (example: taking into account a
temporary runway threshold shift)

AFDM: additional Services
V 1.1
– Included in the basic proposal
 Installation of the software, on the company’s PCs
 Training the FSO team in the operational analysis
 Assistance in the rectification of recurrent malfunctions, in the recorders
– Options
 Operational advice in the case of sensitive analysis
 Customisation of events and reports according to the local operation,
after a period of assimilation

AFDM: Conclusion

AFDM provides a deep insight on the operational performance, much
deeper than the minimum required by the regulatory authorities.

It allows, at low cost and with no other constraints, the development of a
real « Safety Culture » which up to now has been the privilege of large
airlines only (Air France, British Airways, Lufthansa, Cathay Pacific for
example).
