Quick Historical View


• SITA: • Operating the AIRCOM data link services for 25+

years • Initially based on ACARS • In support to AOC

• European Data Link Mandate • Introducing CPDLC/ATN in European upper

airspace • Based on VDLm2 • Sharing the same infrastructure for AOC and ATC

• Challenges

A/G Data Link for AOC Purpose

Airline Operations depend on Data Link

Aircraft Maintenance Engine reports via ACARS

enable preventive maintenance avoiding

costly in-flight breakdowns

Operations Control Aircraft movement

reports via ACARS key to

synchronize operations through airports

Flight Planning Flight plans & weather

transmission to cockpit

enable efficient operation

of modern aircraft

Airline Operations have already made the transition to Data Link

SITA support for FANS & ATN

• 1995 : SITA supports FANS-1 usage since first certification • 2000 SITA deploys VDL capability developed in 1990’s • 2005 SITA adds operational ATN routers for Eurocontrol • 2008 SITA is ATN/VDLm2 CSP for Eurocontrol Maastricht • SITA has VDL partnerships with ANSP’s of Germany, France, Switzerland, Spain, Portugal, Saudi Arabia.

Implementing Rule 4. Conclusion


VGS Partnership Model

Win / Win Approach

- SITA outsources the provision of its A/G communication service (AOC, ATC) to the ANSP - SITA contributes to the ANSP costs for operating the A/G infrastructure

- The ANSP deploys a state-of-the art A/G datalink communication infrastructure at a fraction of the costs it would sustain if developed from scratch - The ANSP owns and operates the infrastructure and develops its know-how - The ANSP receives a cost contribution that is directly linked to the volume of AOC traffic

Non-AOC Operators


Performance / PAs

14

ATN Provider Abort: investigation within Data Link Implementation Service Group (Eurocontrol CRO, ANSP, CSP, airlines, aircraft and avionics manufacturers)

Detected and investigated since the early implementation of ATN CPDLC during LINK2000+ PSG meeting, now DLISG.

Several problems have been confirmed and corrected (CSP radio or network, VDR Deafness, CMU software)

New problems appear and require further investigations.


Performance / PAs

15

• An agreed service monitoring scope is required – taking into account the complete end to end service delivery chain Role of the Central Reporting Office Harmonization of indicators, their metrics and the reporting

process

• If investigations indicate frequency congestion, then stakeholders may consider to expedite multi frequency in Europe

• This is a dynamically changing ecosystem


Certification Framework

16

• ATC usage of data link requires aviation certification authority intervention • European Aviation Safety Agency plans to certify ATC use of VHF data link and

in some way the VHF data link networks used – impact is unclear

• Regulatory framework (i.e. Regulation 552/2004) applies to ATC Components or systems, but what about a service?

• ATC usage can create liabilities that cannot be sustained or justified by airline community VHF data link network operators • ANSP’s often need to comply with government policy on contractual liability

which may be incompatible with airline community network operator policies

• Better certification harmonization is required at European Levels

• Avoid contradicting national requirements

• Streamline and optimize the certification process


Other Challenges

17

• How to reach non-AOC aircraft? Rules of Engagement defined by the Link 2000+ Program Need to raise awareness of non-AOC aircraft Operators

• VDL Multi-frequency CSC Channel loading is increasing but still low (av. ~ 10%) If investigations conclude CSC congestion, then stakeholders may

consider to expedite multi frequency in Europe Deployment of multi frequency will require close cooperation between

all operators

• Tight Schedule – Limited Resources The next deadline, February 2015, is around the corner All ANSPs in the 2015 group are knocking at the door We have to address requests in sequence


Conclusions


• Real time monitoring of the end to end service should be done/coordinated at European level

• Certification and performance requirements imposed by ATC usage of VDL should be harmonized in Europe

• Airlines and ANSPs need to recognize that ATC usage of VDL will fundamentally change the VHF data link network operation

• ATC sharing of VDL avionics is a compromise – it avoids airlines needing additional avionics but the resulting sharing of VDL channels and stations requires the networks to change to meet ATC requirements

• SITA is keen to continue the collaboration to further investigate VDL / ATN issues, but it must be a joint effort from all communication operators (CSPs and ANSPs) as well as other parties like airframers and avionic vendors
