ATIMS - AIRLINE INFORMATION SERVICES - DESCRIPTION AND OPERATION

** ON A/C NOT FOR ALL
1. General
The Standard Airline Operational Control (AOC) applications are datalink applications used by the Airline for maintenance, flight operations and administrative purposes.
They are uploaded into the Air Traffic Services Unit (ATSU) by means of software disks composed of the AOC software (22TX) and the AOC database (24TX) which are located in the storage box.
A. Remote AOC Applications
(1) General
The remote AOC applications are integrated in:
(2) Function
Remote airline applications include both Airline Operational Control (AOC) and Airline Administrative Communications (AAC) applications:
(a) AOC applications
AOC applications concern operations directly related to flight and maintenance purposes:
  • Maintenance applications are integrated in the CFDIU and in the ACMS DMU.
  • Flight operations applications are integrated in the FMGCs.
  • Flight performance applications are integrated in the ACMS DMU.
(b) AAC applications
AAC applications concern administrative communications for the cabin crew and are integrated in the Cabin Terminals (CPMU and DIU).
NOTE: For these reasons, the CFDIU, FMGCs, DMU and Cabin Terminals are named "remote AOC peripherals".
B. Hosted AOC Applications
(1) General
The AOC applications uploaded in the ATSU give the configuration and the architecture of the AOC menu which is accessible through any MCDU,
(2) Function
The main ground users of these applications are the Airline maintenance center, the Airline flight operations and passenger services.
For the AOC applications, the ATSU is an airborne router in charge of:
  • receiving the airline uplink messages and routing them to the corresponding remote AOC peripheral,
  • acquiring the downlink messages from the remote AOC peripherals and sending them to the ground according to the airline routing policy.

2. System Description
A. AOC Reports Transmission
As soon as the ATSU initialization is achieved and the air/ground communication router is active, the AOC applications become active.
(1) Mode of transmission
The reports are either pre-defined, pre-formatted or free text.
They can be generated:
  • automatically: the automatic mode is programmed into the peripheral (event, frequency,...). When the conditions are met for automatic transmission, the peripheral sends the required report to the ATSU. The remote AOC peripheral periodically attempts to send the message until the transmission is successful. In case of ATSU failure, the peripheral gives up the transmission.
  • upon crew request on one MCDU
  • upon reception of an uplink request: an uplink report request is received from the ground and transmitted by the ATSU to the concerned peripheral. An uplink request contains the type of the report to be generated and transmitted (report number) and sometimes, additional information such as trigger conditions. Only one transmission attempt is made.
(2) Datalink communication status
As no buffering capacity is offered by the ATSU, each AOC peripheral only transmits another message when the ATSU has completed the sending of the previous message to the ground. For this reason, the remote AOC peripheral continuously monitors the activity of the ATSU datalink communication to determine the peripheral datalink status. This status has two states: Ready or Not Ready depending on:
  • the validity of the communication link status
  • the correct operation of the ATSU
  • the Satcom or VHF datalink status (one communication network available).
NOTE: If the peripheral datalink status is Not Ready then, the peripheral is considered unable to communicate with the ATSU and the related selection stars are not displayed on the appropriate MCDU pages of the peripheral for manual command.
(3) AOC message structure

B. AOC Applications Description

There are three types of AOC applications:
(1) AOC Type 1
Most of the AOC applications belong to this category. The main functions of these applications are to:
  • collect information from on-board systems
  • transmit and receive air/ground ARINC 618 messages
  • allow the crew to enter information through the MCDU
  • display and print messages and information collected from on-board systems or messages received from the ground
  • transmit reports manually through the MCDU, automatically or on ground request.
NOTE: Some specific AOC Type 1 applications also generate ARINC 429 broadcast data, such as OOOI data (Out/On/Off/In indicates the aircraft situation: at gate, A/C moving before takeoff, takeoff or touch-down).

(2) AOC Type 2 applications
This application consists in collecting information from on-board systems, compiles specific data files and sending them on request or upon internal trigger event to remote AOC peripherals (CFDIU, DMU (ACMS) and the Cabin Terminals).
(3) AOC Type 3
The type 3 AOC applications configure the ATSU host platform with internal parameter values:
  • the routing policy used for downlink messages management function
  • CFDIU programming: activation or inhibition of the transmission of CFDIU downlink reports such as the CFDIU BITE Data report, the ECAM warning report, the Failure report and the POST-FLIGHT REPORT.
NOTE: This configuration is sent to the CFDIU by the ATSU interface services.
(a) Routing policy
For each message transmitted by the AOC application to the ATSU, the ATSU router analyses the destination code and checks the air/ground media availability, one Service Provider (SP) after the other and in order.
Then, the message is sent through the first valid Service Provider. If no available medium is found, the message remains in the router buffer.
The datalink message is sent through the Service Provider applicable to the present airspace which corresponds to a given frequency. There are seven Service Providers:
SP 1 ARINC VHF
SP 2 SITA EUROPE
SP 3 SITA PACIFIC
SP 5 AVICOM
SP 6 CANADA
SP 30 SATCOM
SP 40 HF

(b) CFDIU programming
The CFDIU programming activates or inhibits the generation of the following reports:
  • BITE report: enabled
  • ECAM warning report: disabled
  • Failure report: disabled
  • POST-FLIGHT REPORT: enabled
C. Remote AOC Applications

The interface between the ATSU and the remote AOC peripherals conforms to ARINC 619 Specifications.
(1) DMU AOC application
The ACMS DMU generates and transmits the following reports to the ATSU:
  • Engine cruise report (01)
  • Cruise performance report (02)
  • Engine take off report (04)
  • Engine report on request (05)
  • Engine gas path advisory report (06)
  • Engine mechanical advisory report (07)
  • Engine divergence report (09)
  • Engine start report (10)
  • Engine run up report (11)
  • APU MES/IDLE report (13)
  • APU shut down report (14)
  • Free programmable report N°1 (16)
  • Free programmable report N°2 (17)
  • Free programmable report N°3 (18)
  • Load report (15)
  • ECS report (19)
  • RAT report (20)
NOTE: The report number adjacent to the report designation is that defined in the ACMS specification.

After a message is sent, the DMU waits for the acknowledgement from the ATSU indicated by the Imbedded Message Identifier (IMI):
  • the first transmitted character is A
  • the two other characters are the report number.
(2) CFDIU AOC application
The CFDIU active functions enable the generation and the transmission of the following reports to the ATSU.
(a) BITE data report
The CFDIU transmits the BITE data messages composed of one or more MCDU pages to the ATSU on manual request from the MCDU.
(b) ECAM warning report
The ECAM warnings are automatically transmitted by the CFDIU to the ATSU.
(c) Failure report
The failure messages are automatically transmitted by the CFDIU to the ATSU.
(d) POST-FLIGHT REPORT (on ground) or Current Flight Report (in flight)
The CFDIU automatically transmits the POST-FLIGHT REPORT to the ATSU at the end of the flight leg.
(e) Class 3 Report (on ground)
The CFDIU transmits the Class 3 reports to the ATSU on uplink or on manual request.
(f) Servicing Report (optional)
To generate this report, the CFDIU requires Documentary Data from the ATSU at power-up and at flight phase transition 9 to 10. It then transmits the Servicing Report to the ATSU automatically or on uplink request.

The format of the report is as follows:
---------------------------------------------------
! OCTET NUMBER ! CONTENT !
---------------------------------------------------
! 1 ! "M" Origin Code = ATSU !
---------------------------------------------------
! 2 ! "D" Purpose Code = !

---------------------------------------------------

(3) FMGC AOC application
The AOC application is called ACARS functions in the FMGC.
The ATSU downlinks FMGC reports to inform the airline of the configuration of the aircraft (flight plan reports, position reports,etc...).
The ATSU Router determines which FMGC is intended to receive the uplink message by reference to the sub-label characters.
(4) Cabin Terminals AOC application
The transmission of the downlink reports is only automatic or on ground request.
