ATSU

The ATSU has been designed to take provision of allforeseen evolutions. The modularity concept forsoftware permits to ease data link capability duringall Communication Navigation Surveillance/Air TrafficManagement (CNS/ATM) transitions.

The ATSU software is partitioned into two main parts:- Aircraft interface / host platform and- Data link applications.

AIRCRAFT INTERFACE/HOST PLATFORM SOFTWARE

The aircraft interface/host platform is composed offour services :

- Air/ground communication, used for themanagement of the air/ground communicationmedia,

- Human machine interface, used for themanagement of the CNS/ATM cockpit interfaces(MCDU, printer and alert function),

- On-board peripherals, used for the managementof the communication with the on-boardperipheral units (Data Management Unit (DMU),CFDIU, FMS and Cabin Terminal (CT)),

- System management, used for the acquisition ofthe aircraft parameters for applicationsoftware use and monitoring of the system

(power supply and BITE functions).

DATALINK APPLICATIONS

The data link applications include only AirlineOperation Control (AOC) for the pre FANS configuration.

The AOC applications are dedicated to datacommunication services between the aircraft and theairline facility.

The AOC is composed of :- Remote AOC applications and- Hosted AOC applications.

For the remote AOC applications the ATSU only routesdata to and from AOC peripherals. This routing is incharge of receiving ground messages and routing themto the right AOC peripheral and acquiring messages orreports from these peripherals and sending them to the

ground.

COMM MENU

The Air-Ground communications functions and servicesare active as soon as their initialization is complete.

COMM INITThe initialization (through COMM INIT menu) isconsidered as completed when the ATSU has received avalid Aircraft Registration Number (ARN), AirlineIdent and scan mask.The ARN and Airline Ident are used in the air/groundcommunication as aircraft addressing means.The VHF3 SCAN MASK gives an ordered list of authorizedservice providers usable for data communications.

VHF3 DATA MODEThe VHF3 DATA MODE menu displays the various regionswhich can be selected. Each region is associated witha datalink service provider and a frequency.

VHF3 VOICE DIRECTORYThe VHF3 VOICE DIRECTORY allows the followingfunctions:

- to display a voice frequency directory,- to activate one of these frequencies,- to select the data mode,- to activate the voice frequency contained in

the last received company call,- to manually enter a frequency.

- the communication (router) status of theon-board peripherals.

MAINTENANCE STATUSThe MAINTENANCE menu is composed of three functions:

- TEST which allows to test the link between thecommunication media (VHF3 and SATCOM) and theground,

- STATISTICS permits media and router statistics(number of up linked messages, number of downlinked messages, ) and

- AUDIT to print out exchanged messages per mediaand router depending on selection.

Note : If ON is selected all exchanged messages duringthe flight will be printed.

ATIMS MCDU UTILIZATION

INITIALIZATION PROCEDURE OF THE ATSU ROUTER

This procedure, called Initialization of the ATSURouter, enables the Air-Ground communicationsfunctions and services of the ATSU to be activated.Three essential parameters are required :

- a valid flight ident,- an A/C Registration Number (ARN) and- a valid scan mask.

Otherwise, the ACARS STBY green memo is displayed onthe ECAM .

Lets check the present configuration.

The ATSU is interfaced with the FMGCs and the MCDUsfor Automatic Flight System.

FMGCThe ATSU sends data to both FMGCs on an ARINC 429 busand receives data from both FMGCs on another one.

The ATSU / FMGCs interface is used :- for AOC hosted application for acquisition ofoperational data (origin/destination airport,flight number, fuel on board, ),

- for air-ground communication functions (flightnumber, FMS master/slave, ).

MCDUThe ATSU sends data to MCDUs on an ARINC 429 bus and

receives data from MCDUs on another one.

The ATSU / MCDUs interface is used :- for the AOC application to allow AOC mode

selection, parameter entry (captain name, fuelunits, ), display of AOC specific information(AOC received messages, scratchpad messages, ), and print command,

- for air-ground communication functions to allow

the display of router specific information,crew requests for router modes of operationand parameter entry, print command.

- data block exchanges and

- status transmission.The ATSU sends 2 discrete signals to VDR3 to control:- VDR3 switching between voice and data mode,- port select for VDR3 frequency selection.

SDU1The ATSU sends and receives data from Satellite DataUnit 1 (SDU1) through ARINC 429 links for :

- data block exchanges and

- status transmission.

RMPsThe ATSU sends 1 discrete signal to the 3 RMPs toindicate which entity is controlling the VDR3.The ATSU receives only 1 discrete signal from the 3RMPs used to request the mode switching to the ATSU.

SAFETY PRECAUTIONS

The avionics computers are Electrostatic SensitiveDevices (ESDs). These components are susceptible todamage by electrical sources that would not damageconventional components.The low energy source, that most commonly destroysESDs, is the human body which generates staticelectricity in conjunction with the ground.

The precautions to follow are to :- de-energize all power and signal sources,- place the unit on a grounded conductive work

surface,- ground any tools that will contact the unit...

When it is specified on the maintenance manual.
