Summary
Conclusions
Today‘s Shortcomings
 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
 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

Cost-Benefit Consideration
still in progress
 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.

Summary (1)
 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.
 The continued use of today's operational environment will result in
further frequency shortages.
 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 (2)
 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.
 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.

Conclusions (1)
Data Link Services
There is a strategic requirement to introduce Air- Ground Data Link
services within DFS controlled airspace.
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

Conclusions (2)
Data Link Services
 Data Link Services (main categories only)
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.

Conclusion (3)
Air-Ground Data Link Media
 Non- time critical ATS Data Link- messages will use VDL M2
(medium timeframe, starting 2005)
 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 Linkmessages - and if so the type of the media - needs to be defined till
2002.
