presentation overview
Presentation overview
  • Genesis of ‘Package I’
  • Ground Surveillance (GS) applications
  • Airborne Surveillance (AS) applications
  • Future packages
  • Related European projects and programmes
  • Concluding remarks
background for package i
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
objectives of package i
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
step by step approach
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
rationale for package i 1 2
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
rationale for package i 2 2
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
  • 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
gs application rationale
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

as application rationale
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

package ii
‘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!
package iii
‘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
other considerations
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

concluding remarks 1 2
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
concluding remarks 2 2
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
