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 Slide 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. Slide 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 2006. DFS customers are requesting Data Link Services today, in order to receive enhanced and improved overall quality of ATC Services. Slide 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 Slide 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. Slide 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 2001. 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.
