ADS-B TIS-B Architecture Definition Major
Objectives

• Establish a common view of ADS-B TIS-B
  functions
• Facilitate cross-communication between the
  various corresponding European projects
• Provide a means towards Interoperability
• Support the Validation activities
• Establish a logical and traceable bridge from
  requirements (OSED, SPR, INTEROP) to
  infrastructure component specifications
• Support the Validation Infrastructure Development
  (AVT)
• Support the CBA activities

Ground Functional and PhysicalArchitecture
Definition

• ADS-B TIS-B Functional Architecture
• Intermediate ground FA (Functional Architecture)
  document focused on TIS-B is available
• Work is on-going for the next version including
  ground ADS-B aspects (May 2003)
• At a later stage, airborne aspect resulting from
  the study on the airborne functional architecture
  will be included
• ADS-B TIS-B Ground Physical Architecture
  (allocation of requirements to physical
  components) has started

Airborne Surveillance Functional Architecture
Study

• ASFA Study constitutes a major ADS Programme
  airborne related activity centred around the
  Airborne SDPD function
• Project teams comprise key airframers and
  avionics industry
• Project delivers
• Position Paper on ACAS-ASAS/ADS-B Relationship
• Functional, performance and interface
  requirements for an Airborne SDPD prototype
• Including development recommendations derived
  from an analysis of existing Ground SDPD systems
• Airborne Surveillance Functional Architecture
  Definition
• Workshops facilitated exceptional platform for
  extensive discussions between major industry
  parties

Package I CBA Activities
13
Package I Cost Benefit Analysis

• Package I CBA Study is on-going
• Review Group including NATS, IATA, LH, SAS,
  IAOPA, Rockwell-Collins Airbus CARE-ASAS
• Focuses on a sub-set of applications (ground and
  air) with significant potential for operational
  benefits
• The current CBA document shows
• High benefits (up to 2Bn) from
• SSR radar replacement
• Enhanced Visual Approaches
• Enhanced Sequencing and Merging
• Also, strong indications that other Package I
  applications will generate a very positive return
  on investment
• Crossing and Passing en-route extension of SM
  to the approach phase

14
Airborne Infrastructure Equipage Options and
Scenarios

• Package I Equipage Options
• Option 1 ADS-B out
• Option 2a ADS-B in ATSAW
• Option 2b ADS-B in ATSAW Spacing w/o
  automation
• Option 3 ADS-B in ATSAW Spacing with
  automation
• Option 3 upgradable to Package II at relatively
  low cost
• Package I Equipage Scenarios
• For Air Transport Helicopters (off-shore)
• Scenario 1 applying equipage option 2a
• Scenario 2 applying equipage option 2b
• Scenario 3 applying equipage option 3
• For General Aviation Military applying equipage
  option 1

15
Initial Cost Benefit Results(ECAC-wide)
Equipage Option/Scenario 3 upgradable at low
cost to support Package II
16
Package II CBA Considerations

• Application Examples
• Airborne separation applications (Cluster Control
  alone would account for 1B)
• Airborne self-separation applications in
  low-density airspace (initial high level
  estimates of 1.5B not investigated further)
• Upgradability of Airborne Architecture options,
  from Package I to Package II requirements is a
  key issue under consideration

17
Conclusions

• ADS/B and TIS-B Architecture Definition
• Establishing a logical and traceable bridge from
  Requirements to Infrastructure Component
  Specifications
• Providing a means towards Interoperability
• Ground Functional and Physical Architecture
  Definition
• Airborne Surveillance Functional Architecture
  Study
• CBA Activities
• The work is on-going for review by the Review
  Group
• Package I shows potential for a positive CBA
• Evolution to Package II
