SITA Aircraft Data Link Service

• Creation of SITA in 1949 by airlines to provide
  them with shared network services.
• Expansion of data network coverage
• VHF AIRCOM ground stations
• Satellite AIRCOM INMARSAT ground stations
• The AIRCOM Data Link Service provides aircraft
  with a means to exchange data with airline
  systems and ATS application systems connected to
  the SITA terrestrial network.
• Today SITA provides ACARS services to over 5,000
  acft for AOC comms. On average we provide
  services to 3,000 acft daily that exchange in
  excess of 350,000 mesages

SITA AIRCOM Services

• SITA provides AIRCOM Data Link service for use by
  Aircraft Communication Addressing and Reporting
  System (ACARS) avionics.
• Plain Old ACARS (POA)
• ACARS Over Aviation VHF Link Control (AVLC) (AOA)
• Internetworking

7
AIRCOM ATS Services

• According to IATA estimates, there are about 1200
  FANS 1/A equipped aircraft.
• 20 ATS providers around the world are
  providing/planning to provide FANS 1/A based
  services
• On regional context the following airlines have
  datalink capabilities
• TAM, LANCHILE, COPA, MEXICANA, ACES, AIR JAMAICA,
  TACA, MARTINAIR, VARIG.

8
AIRCOM ATS Services

• Sets of data link applications using ACARS
• Pre-FANS applications that use only the basic
  text messaging capability of the ACARS avionics
• Departure Clearance (DCL) and Oceanic Clearance
  (OCL)
• Automatic Terminal Information Service (ATIS)
• The FANS applications which require special
  processing capability in the user aircraft
• Automatic Dependent Surveillance (ADS)
• Controller Pilot Data Link Communications (CPDLC)
• ATC Facilities Notification (AFN)

ACARS to ATN Transition

• As part of LINK 2000 (the Eurocontrol Link
  Program Steering Group)an industry group lead by
  Boeing was formed with the objective of examining
  ways to accommodate FANS 1/A aircraft in ATN
  Baseline 1 airspace, to provide ATS providers
  with aircraft to justify investment and maintain
  progress on domestic datalink infrastructure
  investment
• To support FANS-1/A aircraft in ATN airspace IRRF
  has considered a solution based in two kinds of
  gateways internal and external.
• The gateway provides the fundamental mechanism
  for ATN-based ATS Providers to communicate with
  FANS-1/A aircraft, and vice versa
• SITA is actively involved with IRRF group in
  order to develop/provide an external gateway

VHF ACARS to VDL transition

• ICAO VHF Digital Datalink (VDL)
• Mode 2
• ACARS replacement
• ATN compatible
• SARPS were included in Annex 10 in Nov1997
• 3Kbits/s throughput for ATC use
• transition solution
• Mode 3
• Mode 4

17
VHF ACARS to VDL transition

• SITA will increase VHF AIRCOM data link capacity
  by introducing VHF Digital Link Mode 2 service
  providing 10-20 times more capacity per channel.
• Industry has defined the ACARS over AVLC (AOA)
  standard as a means to operate existing ACARS
  applications over the VDL 2 network
• SITA is currently trialling the AOA service with
  a major European Airline
• The VGS (VDL Mode 2 and ACARS capable) has been
  delivered in October 2000 and deployment started
  beginning in January 2001

ATN Ground Applications AMHS Plans

• SITA is planning to build an Aeronautical Message
  Handling Service (AMHS) that fully complies to
  the ICAO ATN AMHS Standards and Recommended
  Practices
• SITA is assessing ATS provider requirements for
  introduction and use of AMHS services in order to
  determine when the service should be rolled out
• SITA can provide either a back-up or primary AMHS
  service

20
ATN Ground Applications AMHS Plans

• ATS ground-to-ground communications are
  increasingly using generic telecommunications
  services e.g
• the FAA Telecommunications Infrastructure (FTI)
  initiative to replace the FAAs leased lines with
  a Frame Relay and ATM backbone
• the Eurocontrol CFMU regional IP service to
  support the Enhanced Tactical Flow Management
  System
• SITA encourages ATS providers to consider
  providing AMHS services over an IP network
  service, ATN ground/ground routers are not
  essential for AMHS services

21
AIRCOM ATN Services

• VDL Mode 2/ATN
• VDL/ATN will support the ICAO ATN CM, CPDLC, ADS,
  and FIS applications
• Launch September 2002
• Successful Flight tests with Eurocontrol January
  2002-CPDLC messages exchanged end-to-end
• VHF Ground Stations (VGS) POA/AOA/ATN Capable
  Deployment in 2002
• GACS Gateway (Genereric ATN Com Service)
• permits legacy ACARS applications to use an ATN
  service
• provides ATN interface for new binary (AOS ATS)
  applications
• SITA is working with Eurocontrol, BA and LH on
  GACS trials
• Aeronautical Mobile Satellite Services (AMSS)
  Data-3
• Suports connection to ATN network

22
By concluding...

• SITA works with the ATS providers developing data
  link applications to ensure they are accessible
  to the AIRCOM customer airlines.
• SITA encourages the use of the existing ACARS
  AIRCOM infrastructure to the ATS providers for
  initial ATS datalink applications (D-ATIS, DCL,
  OCM, FANS 1/A)
• ATC providers implementing CPDLC services will
  have to offer them to ATN and FANS-1/A equipped
  aircraft to have a significant impact on airspace
  capacity by 2005
• SITA is willing to work/partner with ATS
  providers to support plans and trials for ACARS
  based ATS applications and ATN service provision
  including AMHS
