DFS Strategy 23-Sep-99Chart 14 DFS is a contributor to the ongoing
Link 2000+ 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 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.
