Data link is not new..

• Airlines have been using it for over 20 years for
  Operational Communications
• Air Navigation Service Providers have been using
  it for over 15 years for initial ATC applications
• Global coverage via VHF and Satellite media
• Over 10,000 aircraft are equipped with ACARS data
  link
• CPDLC/ATN/VDL2, as being implemented by
  Link2000, is a significant next step forward to
  enable delivery of increasingly sophisticated ATC
  messages

Future Trends .

• ACARS VHF networks have typically been deployed
  by the airline communications service providers
  SITA and ARINC
• Some Air Navigation Service providers in the
  Link2000 programme want to continue with this
  arrangement
• Nav Portugal, Eurocontrol Maastricht
• Others prefer to take on responsibility
  themselves for the VHF network infrastructure
  provision and operation in partnership with an
  airline service provider
• DFS, AENA
• For Air Navigation Service providers to optimise
  investments in new CNS technology, SITA has been
  promoting the concept of ANSPs in each region
  creating a regional CNS service provider to
  operate networks like VDL that are best managed
  at regional level

The SITA ATN Service

• Available today with 24/7 monitoring
• Based on the Sofreavia Pro-ATN Router
• Extensive flight trials with Eurocontrol aircraft
• Supporting on-going flight trials with Air Europa
• Certification flights planned in the near future
• Supporting testing with avionics vendors

SITA and Link2000

• Airlines that have elected to use the SITA ATN
  Service include
• Lufthansa (20 A320)
• Federal Express (15 A310)
• Air Berlin (2 B737)
• Air Europa (19 B737)
• Hapag-Lloyd (20 B737)

• Air Navigation Service Providers that have
  elected to use or partner with SITA include
• DFS in Germany (Partner)
• AENA in Spain (Partner)
• NAV EP in Portugal
• Eurocontrol Maastricht UACC (via
  internetworking)

Maastricht UACC use of SITA ACARS for FANS-1/A

• Maastricht UACC started accommodating FANS 1/A
  equipped aircraft in PETAL Phase 2 and this path
  generated the vast majority of the PETAL CPDLC
  traffic
• Maastrichts PETAL system used the SITA ACARS
  services to communicate with FANS-1/A aircraft
  and the new Link 2000 CPDLC applications
  continues to use the SITA ACARS service for
  FANS-1/A aircraft.
• Link2000 States need to make a collective
  decision on whether or not to accommodate FANS
  1/A aircraft
• Numbers of FANS 1/A equipped aircraft is expected
  to continue to rise
• FANS 1/A aircraft will be exempt from the planned
  Mandate

VDL Customers

• Operators using the SITA VDL Service include
• AAL (25), AEA (4) , AFL (18), AFR (15), DLH (17),
  FDX (12), JAL (12), QFA (19), RAM (2), SWR, TRS
  (3), UVA (2)
• Average monthly total of 170 VDL equipped aircraft

ATN/VDL Performance

• Evaluated via Eurocontrol laboratory
  testing/Eurocontrol flight trials/Air Europa
  delivery flights and Air Europa revenue flights
• Over 22 flight hours of service evaluation
• Average application level round trip delay is
  around the two second mark
• Eurocontrol PSG/12 quote

14
VDL Service Partnerships

• SITA has concluded VHF Data Link partnership
  agreements with
• AENA (Spain) in December 2002
• DFS (Germany) in December 2004
• Agreements are similar in that our partners
  will/have assumed ownership and responsibility of
  control/monitoring of the VHF data link stations
  through which they will deliver the Link2000
  Services

Partnership VDL Deployment Status

• Spain (AENA)
• Deployment project completed
• 21 VGS (ACARS/VDL) stations deployed and now
  operational
• Germany (DFS)
• 19 installed VGS to be transferred to DFS over
  next 6 months
• Further 8 or 9 VGS to be installed in 2007 to
  supplement VDL coverage in Germany

18
Conclusions

• SITA is committed to facilitating the pragmatic
  evolution of ATN implementation and ATN/VDL
  service delivery
• However, delivery of uniform data link benefits
  to FANS 1/A equipped airlines should continue to
  be supported in the transition to ATN
• The selection of SITA by the leading Air
  Navigation Service Providers in Europe and
  pioneer airlines demonstrates their confidence in
  SITAs ability to deliver services and products
  to the highest levels of customer satisfaction
