COMM MENU

The air-ground communications functions and services are active as soonas their initialization is complete.

NOTE: The AUDIT PRINT PAGE SET OFF functionis used to disablethis function directly from this page without having to get accessto the AUDIT page.

COMM CONFIGThe initialization through COMM CONFIG menu is considered ascompleted when the Air Traffic Service Unit (ATSU) has received avalid aircraft registration number, airline identification and scan mask.The aircraft registration number and airline identification are used inthe air/ground communication as aircraft addressing means. The VHF3SCAN SEL gives an ordered list of authorized service providers usablefor data communications.

VHF3 DATA MODEThe VHF3 DATA MODE page shows the various regions, which canbe selected. Each region is associated with a data link service providerand a frequency.

VHF3 VOICE DIRECTORYThe VHF3 VOICE DIRECTORY page fulfills the following functions:- display a voice frequency directory,- activate one of these frequencies,- select the data mode,- activate the voice frequency contained in the last received CO CALLmessage,- manually enter a frequency.

COMM STATUSThe COMM STATUS pages are used to verify the communicationstatus of ATSU:- the air/ground communication media status; VHF3, SATCOM (ifinstalled) and HF (if HFDR installed),- the communication (router) status of the on-board peripherals.

MAINTENANCE STATUSThe MAINTENANCE menu is composed of three functions:- TEST, which is used to test the link between the communicationmedia (VHF3, SATCOM and HF if installed) and the ground,- STATISTICS used for media and router statistics: number of uplinked messages, number of down linked messages,- AUDIT to print out exchanged messages per media and routerdepending on selection.

ATSU ROUTER INIT & TESTS THROUGH MCDU (2)

INITIALIZATION PROCEDURE OF THE ATSU ROUTER

GENERALThis procedure, called initialization of the Air Traffic Service Unit(ATSU) router, enables the air-ground communications functions andservices of the ATSU to be activated. Three essential parameters arerequired:- a valid airline identification (ACARS and STANDARD A/L ID),- a valid A/C registration number (A/C REGISTR) and,- a valid scan mask.Otherwise, the ACARS STBY green memo is displayed on theEngine/Warning Display (EWD).

NOTE: According to the pin programming activated on the FlightWarning Computer (FWC) ("ACARS installed" or "ATSUinstalled"), the COMPANY DATALINK STBY green memois displayed instead of the ACARS STBY memo.

A/C REGISTRATION NUMBER AND FLIGHTIDENTIFICATIONThe A/C registration number is sent by the Centralized Fault DisplayInterface Unit (CFDIU). The ATSU creates the flight identificationby concatenating the airline identification parameter and the flightnumber parameter coming from the Flight Management System (FMS).The airline identification is not available and must be entered.

SCAN MASK VALIDATIONThe last parameter required is the scan mask validation. The threeVHF SCAN SELECT pages give an ordered list of service providersusable for VHF data communications. TEST TLS and TEST HAMare activated only for test and shall not be selected for airlineoperations. The NEW SCAN SELECT function is used to erase theprevious selection. The VHF3 SCAN MASK is compulsory for therouter operation.

SCAN MASK VALIDATION (CON'T)The scan mask must be a prioritized list of VHF service providerscontracted by the airline. Select one or more service providers in theappropriate priority order to compose the scan mask. SITA EUR/AFRand ARINC AFRICA are selected as an example. The SCAN SELACTIVATE allows the new selection to be loaded into the ATSU.When the initialization of the ATSU router is completed, the ACARSSTBY green memo goes off.

OPERATIONAL TEST

VOICE MODE TESTThis procedure, called operational test of the ATSU, serves to checkthe ATSU router configuration and test the voice mode. Theinitialization of the ATSU router is completed. The ATSUautomatically controls data frequencies in the order defined in theVHF3 SCAN SELECT menu, but a service provider can be manuallyselected. The VHF3 VOICE DIRECTORY page serves:- to activate one of the displayed frequencies configured by the AirlineOperational Control (AOC) application,- to activate the voice frequency requested by the ground (CO CALL),- to manually enter a frequency and,- to go back to data mode.When the OPS frequency is activated (132.225 given as an example),the ATSU controls the VHF3 frequency in VOICE mode. On theRadio Management Panel (RMP), the ACARS indication stays inview in the active window. In this mode, communication tests withthe ground can be done.

ATSU INITIALIZATION CHECKThis procedure, called VHF3 link test of the ATSU, checks the VHF3link between the A/C and the ground. A check of the ATSUinitialization is done through the VHF3 DATA MODE menu, theVHF3 VOICE DIRECTORY menu and the COMM STATUS menu.VHF3 must be operational, the VHF3 link available and in DATAmode.
