3 Air-Ground Data Link - DFS Strategy 23-Sep-99Chart 3  increasing number of aircraft results in  reaching capacity limits on voice frequencies/ frequency shortage  overload of executive controllers  increasing challenge to ensure the safety of flight Today‘s Shortcomings  voice communication implies potential of misunderstandings  no automated exchange of information between data processing systems in the Air and on the Ground  Airline requirements regarding data link are not satisfied

4 Air-Ground Data Link - DFS Strategy 23-Sep-99Chart 4  Strategies, approved by DFS  ATM  EATMS-OCD  EATCHIP-Communications Strategy  Important Programs  FAA- NEXCOM- Program  LINK  PIT - PETAL Integration Team  Military Aviation  There was no specific military requirement for ATS-Data Link Services identified yet.

14 Air-Ground Data Link - DFS Strategy 23-Sep-99Chart 14  DFS is a contributor to the ongoing Link CBA.  The objective is to conduct a European-wide analysis.  The uncertainty* of early conducted cost estimations with particular focus to DFS was very high. Therefore, the introduction of Data Link Services** could not be justified by economic reasons only. * At the moment of already conducted estimations there were very few reliable sources of monetary information regarding costs and benefits. ** There was no individual investigation particular to singular data link services. Cost-Benefit Consideration still in progress

15 Air-Ground Data Link - DFS Strategy 23-Sep-99Chart 15  The cost/ benefit-ratio could not be finally calculated. There are a lot of currently unknown factors in the equation. This leaves the risk, that the figure will not justify the need.  The introduction of Air-Ground Data Link Services could not only be justified by a cost/ benefit-analysis. Summary (1)  The continued use of today's operational environment will result in further frequency shortages.  Future ATM-concepts depend on Air-Ground Data Link Services.  Air- Ground data communications is a major component of the „ATM Strategy for 2000+“.  The benefits of Air-Ground Data Link Services were demonstrated in the framework of PHARE and during the PETAL Life Trials.

16 Air-Ground Data Link - DFS Strategy 23-Sep-99Chart 16  The migration from ACARS to VDL M2 as the next generation AOC- Data Link media seems to be decided by the Airlines and the Service Providers (SITA/ ARINC).  Service Providers already decided on installation and operation of VDL M2 Ground- Infrastructure. Summary (2)  Airspace capacity shortages are expected when Data Link Services are not introduced before  DFS customers are requesting Data Link Services today, in order to receive enhanced and improved overall quality of ATC Services.

17 Air-Ground Data Link - DFS Strategy 23-Sep-99Chart 17 There is a strategic requirement to introduce Air- Ground Data Link services within DFS controlled airspace. Conclusions (1) Data Link Services Therefore DFS introduces Air-Ground Data Link Services in a phased approach: Phase 0(starting 1999): Initial Data Link Applications (Result of the Projects INDAL- DATIS and -DDCL) Phase 1(starting 2005): non- time critical Data Link Services depending on operational requirements: Phase 2(starting 2007): time critical Data Link Services

18 Air-Ground Data Link - DFS Strategy 23-Sep-99Chart 18  Data Link Services (main categories only) Conclusions (2) Data Link Services Phase 1 (starting 2005): non- time critical Services  CPDLC (DCL, CIC- non time critical)  ADAP (CAP, SAP)  D-FIS (D-OTIS, D-SIGMET)  other Services (e.g. FLIPCY) additional Phase 2 Services (optional starting 2007): time critical Services  CPDLC (CIC-time critical)  ADAP (PPD, ADS)  D-FIS (D-RVR)  other Services.

19 Air-Ground Data Link - DFS Strategy 23-Sep-99Chart 19  Non- time critical ATS Data Link- messages will use VDL M2 (medium timeframe, starting 2005) Conclusion (3) Air-Ground Data Link Media  The need for and the type of a “complementary Data- Link Media” (in addition to VDL M2) needs to be investigated and decided till In the light of the DFS- decision on Mode S Enhanced Surveillance, SSR Mode S communications will get special attention.  The operational requirement for the use of time critical ATS- Data Link- messages - and if so the type of the media - needs to be defined till 2002.
