1. Operational applications enabled by ADS-B Francis CasauxCARE/ASAS manager

2. Presentation overview • Genesis of ‘Package I’ • Ground Surveillance (GS) applications • Airborne Surveillance (AS) applications • Future packages • Related European projects and programmes • Concluding remarks

3. Background for ‘Package I’ • Based on a proposal made at the ADS-B Symposium in Rome (12-14 March 2002) • Development coordinated with: • EUROCONTROL programmes • European Commission (EC) • EC funded projects (e.g. NUP II) • IATA/AEA initiative (JURG/JAFTI) • EUROCAE/WG51

4. Objectives of ‘Package I’ • Focus on operational applications suited for core European high-density traffic areas without excluding other areas • Operational airborne and ground user needs for ADS-B are considered • Develop the operational and technical standards required for the early implementation of ADS-B applications

5. Step-by-step approach • Wide range of operational applications associated with different issues (i.e. PO-ASAS categories) • Ground and airborne architectures need to evolve step-by-step • Ground and airborne evolutions need to be coordinated with time objectives

6. Rationale for ‘Package I’ (1/2) • Users’ need: Safety as well as flexibility & capacity benefits (e.g. IATA/AEA JURG/JAFTI) • Feasibility: • Pre-existing work from EUROCONTROL programmes and EC projects • Trials already performed in Europe and USA • Complexity: No change in current responsibility for separation provision

7. Rationale for ‘Package I’ (2/2) • Market: Opportunities to equip and retrofit existing equipment to fulfil the requirements • Time-scale: Implementation foreseen within 5-10 years • Building Package II on experience: • Airborne surveillance performance and use • Increase involvement of the flight deck in ATM

8. Deliverable • Title: ‘Description of a first package of GS/AS applications’ • Version 2.2 - September 30, 2002 – 58 pages • Developed within the framework of Activity 5 of CARE/ASAS • Covering letter from the Joint Co-ordination Board signed by the European Commission and EUROCONTROL

9. GS application rationale • Pragmatism: • They make sense in an area with good ATC • They can be implemented more quickly • Simplicity: • GS applications require only ‘ADS-B out’ • Aircraft do not need to be equipped with ‘ADS-B in’ or ASAS

10. SSR ADS-B Receiver ground-station ATCCentre or tower GS applications ADS-B out

11. GS applications in ‘Package I’

12. AS application rationale • Pragmatism: • No significant change from current Rules of the Air (i.e. No delegation of separation responsibility) • AS applications, which can implemented more quickly, were selected • Simplicity: • Airborne Traffic Situational Awareness (ATSA) applications • Airborne Spacing (ASPA) applications

14. ATSA applications in ‘Package I’

15. ASPA applications in ‘Package I’

16. ‘Package II’ • Enhanced GS/AS applications from ‘Package I’ • E.g. ‘Package I’ applications that prove too complex • Airborne Separation applications (i.e. PO-ASAS category III applications) • Airborne Self-separation applications (i.e. PO-ASAS category IV applications) in low-density airspace • Applications already studied in the EC projects • Applications providing greater benefits to be gained - and proved!

17. ‘Package III’ • Enhanced GS/AS applications from ‘Package II’ • Airborne Self-separation applications (i.e. PO-ASAS category IV applications) in medium/high-density airspace

18. Other Considerations • Development and implementation of ‘Package I’ is the first step. • ‘Package I’ will lay the ground work for further development and applications • Further progress requires difficult issues to be resolved: • transfer of separation responsibility • new separation standards and spacing standards • more demanding system performance requirements

19. EC on-going projects • NUP II: North European ADS-B Network Update Programme • MFF: Mediterranean Free Flight • MA-AFAS: More Autonomous Aircraft in Future ATM System • EVP: European Validation Platform • Gate-to-Gate

20. Other European Activities • EUROCONTROL – AGC & ADS programmes • Concept of operation • Service descriptions • EUROCONTROL Experimental Centre • Co Space project • CARE/ASAS • NLR • CENA • Glasgow University, Delft University, ….

22. AS application mapping

23. EC future projects • C-ATM: Co-operative Air Traffic Management – Phase 1 • SEAP: Large Scale South European ADS pre-implementation Programme • AAA: Advanced Airborne System Applications

24. Concluding remarks (1/2) • Change of Paradigm: The idea of transferring separation responsibility to the aircraft is controversial • GS applications require no change in paradigm • AS applications are more novel but ‘Package I’ deliberately avoids this issue • ADS-B & ASAS should be seen as evolutionary opportunities, not radical change, and controllers are still essential

25. Concluding remarks (2/2) • ‘Package I’ is a pragmatic approach leading to early implementation • The approach is flexible for States, ATS providers and airspace users • Most of the energies should be directed for Package I • R&D work for future packages is also essential
