4.2. A300/A310/A300-600 aircraft
The aircraft data recording system includes an expanded Aircraft Integrated Data System. The AIDS allows condition and performance monitoring and/or specific engineering investigations by the operators. An additional optional Data Management Unit (DMU) can also be installed. On the A300/A310/A300-600 aircraft types, all equipment is Buyer Furnished Equipment (BFE).
Airbus is not responsible for the AIDS/ACMS features: architecture, functions, ground requirements. As a consequence, no specification defining standard reports is available. This means that the format of the produced data is not known in advance. Saying there are as many formats as operators would be a little bit of a caricature but not that much.
Therefore, no automatic data collection for fully automated aircraft performance monitoring purpose is available for A300/A310/A300-600 aircraft types. On the operator’s side, the alternatives are: -To manually observe the cruise phases. In that case, some constraining
stability criteria must be taken into account, -To build an in-house tool to be able to convert the material produced by the
aircraft DMU into an appropriate format (provided all required data is available).

4.3. A320 family/A330/A340 aircraft
4.3.1. Introduction
The analysis requires many parameters for one record or in-flight data set. Each in-flight data set is like a snapshot of the aircraft conditions. As many records as possible should be obtained to increase the reliability of the statistical results.
This chapter will provide an overview of the various aircraft recording systems and the way to retrieve the information.
The Aircraft Recording and Monitoring Systems are basically divided into three categories:
1.
The Centralized Fault Display System (CFDS)
2.
The Flight Data Recording System (FDRS)
3.
The Aircraft Integrated Data System (AIDS) for the A320 family aircraft or the Aircraft Condition Monitoring System (ACMS) for A330/A340 aircraft
The FDRS and AIDS/ACMS systems are devoted to collecting some aircraft parameters. The following diagram sums up the functions of both systems. In both cases, the feedback from the aircraft allows the operators to take the appropriate actions.

Only the AIDS/ACMS system is described in the following as it is the appropriate system to collect data for automatic processing thanks to the APM program.
