6. April 2003ASAS TN 28-30 April 2003 Workshop5 OSEDs, SPR, INTEROP Functional Architecture (FA): identification of: functions and sub-functions (functional requirements) high level data flows rules for data exchange Physical Architecture (PA): mapping of the FA requirement onto components to support infrast. dev. Includes performance requirements/specifications Detailed interfaces (protocol, ASTERIX, etc) Infrastructure Component Development (AVT) Top-Down Flow of Requirements From ED78A to Validation platform Traceability Interoperability elements

7. April 2003ASAS TN 28-30 April 2003 Workshop6 Ground Functional and Physical Architecture Definition l ADS-B & TIS-B Functional Architecture: v Intermediate ground FA (Functional Architecture) document focused on TIS-B is available v Work is on-going for the next version including ground ADS-B aspects (May 2003) v At a later stage, airborne aspect resulting from the study on the airborne functional architecture will be included l ADS-B & TIS-B Ground Physical Architecture (allocation of requirements to physical components) has started

13. April 2003ASAS TN 28-30 April 2003 Workshop12 Package I CBA Activities

14. April 2003ASAS TN 28-30 April 2003 Workshop13 Package I Cost Benefit Analysis l Package I CBA Study is on-going : v Review Group including NATS, IATA, LH, SAS, IAOPA, Rockwell-Collins; Airbus; CARE-ASAS v Focuses on a sub-set of applications (ground and air) with significant potential for operational benefits l The current CBA document shows : v High benefits (up to 2Bn€) from : © SSR radar replacement © Enhanced Visual Approaches © Enhanced Sequencing and Merging; v Also, strong indications that other Package I applications will generate a very positive return on investment : © Crossing and Passing en-route; extension of S&M to the approach phase

15. April 2003ASAS TN 28-30 April 2003 Workshop14 Airborne Infrastructure Equipage Options and Scenarios l Package I Equipage Options: v Option 1: “ADS-B out” v Option 2a: “ADS-B in” ATSAW v Option 2b: “ADS-B in” ATSAW & Spacing w/o automation v Option 3: “ADS-B in” ATSAW & Spacing with automation © Option 3 upgradable to Package II at relatively low cost l Package I Equipage Scenarios : v For Air Transport & Helicopters (off-shore) : © Scenario #1 applying equipage option 2a © Scenario #2 applying equipage option 2b © Scenario #3 applying equipage option 3 v For General Aviation & Military applying equipage option 1

16. April 2003ASAS TN 28-30 April 2003 Workshop15 Initial Cost Benefit Results (ECAC-wide) Equipage Option/Scenario 3 upgradable at low cost to support Package II

17. April 2003ASAS TN 28-30 April 2003 Workshop16 Package II CBA Considerations l Application Examples: v Airborne separation applications (Cluster Control alone would account for ~1B€) v Airborne self-separation applications in low-density airspace (initial high level estimates of ~1.5B€; not investigated further) l Upgradability of Airborne Architecture options, from Package I to Package II requirements is a key issue under consideration

18. April 2003ASAS TN 28-30 April 2003 Workshop17 Conclusions l ADS/B and TIS-B Architecture Definition : v Establishing a logical and traceable bridge from Requirements to Infrastructure Component Specifications v Providing a means towards Interoperability v Ground Functional and Physical Architecture Definition v “Airborne Surveillance Functional Architecture” Study l CBA Activities : v The work is on-going for review by the Review Group v Package I shows potential for a positive CBA v Evolution to Package II
