3. CPDLC LINK 2000+
European Organisation for the Safety of Air Navigation

4. Operational CPDLC in the Cockpit

5. Overview LINK http://www.eurocontrol.int/link2000
LINK implementation is well underway
The extra Capacity is required, essential to implement in time
LINK provides the infrastructure for future datalink enhancements
E.g. CASCADE programme
LINK is seen as a necessary step towards SESAR
Continued co-ordination with FAA is ongoing
Was in place with FAA CPDLC Programme
Continues in PARC/ Datalink Roadmap initiative
Using ATN and VDL2

6. Implementing Rule for Data Link Services
European Organisation for the Safety of Air Navigation

7. Milestones of Data Link Services Mandate
The European Commission, gave a Mandate to EUROCONTROL for the development of an Implementing Rule (IR) for Datalink Services on 30th May 2005
Delivery of Initial Plan
15 July 2005
Delivery of Regulatory Approach
January 2006
Draft final report including proposed draft Implementing Rule
May 2006
Delivery of the final report including the draft Implementing Rule and the justification material
September 2006

8. CPDLC – ADS-B CASCADE
