2. Projects EMERALD and EMERTA EMERALD WP5 Work Task WP5.1: Identification of potential ASAS applications Task WP5.2: Detailed feasibility assessment of selected ASAS applications Task WP5.3: Users’ Interview Task WP5.4: Assessment report and RTD plan Task WP5.5: Users’ feedback and final results presentation

4. Projects EMERALD and EMERTA WP5 recommendations The proposed RTD plan be used as a guide for further research into the ASAS domains by the RTD funding authorities The RTD activities described in the RTD plan be undertaken quickly in order to cope with the EATMS schedule for ‘Co-operative ATM’ Co-ordination between all organisations involved in ASAS studies be undertaken

6. Projects EMERALD and EMERTA Objectives of Project EMERTA (1/3) To establish the feasibility of using emerging NGSS services ‘as they are’ to meet Air Traffic Service (ATS) and Airline Operation Center (AOC) requirements. This will include the definition of a European-level NGSS demonstration/validation project. To support a European input to international standardisation activities in such forums as ICAO and RTCA/EUROCAE, insofar as they are concerned with the technologies and concepts covered by Project EMERTA.

7. Projects EMERALD and EMERTA Objectives of Project EMERTA (2/3) To provide inputs to the specification of detailed requirements for a second generation of Low/Medium Earth Orbit (LEO/MEO) satellite systems and services, for deployment beyond the year 2005. To assess the practical feasibility of the early introduction, in the European ATM environment, of one or more selected ADS- B/ASAS application scenarios, paying particular attention to safety and transition aspects. This will be supported by an outline indication of the cost/benefit issues associated with the scenario(s).

8. Projects EMERALD and EMERTA Objectives of Project EMERTA (3/3) To develop initial indications and guidelines on how to deploy ADS-B in Europe, in the context of the ASAS concept, in terms of the potential requirement for reserved airspace and how best to deal with a mixed aircraft population (where some aircraft have an ASAS capability, but others do not).

9. Projects EMERALD and EMERTA TIS-B conclusions TIS(-B) has a role to play in enabling the initial implementation of ASAS applications An ongoing role to support ASAS operations could also be identified. The concept of a service volume is key. An agreed TIS(-B) concept must be defined as the international standardisation activity continues and further requirements become available.

10. Projects EMERALD and EMERTA For EMERTA, two applications were chosen: Enhanced Visual Acquisition (EVA) of other traffic for see-and-avoid Station Keeping on Approach (SKA ) Two applications were also taken from EMERALD: Closely Spaced Parallel Approaches (CSPA) Longitudinal Station Keeping (LSK) ASAS Applications

11. Projects EMERALD and EMERTA EMERTA Conclusions (1/2) Technology is available to support basic ASAS applications Major gap is in the surveillance data quality SKA has been shown to be feasible in the short- term TIS-B could be an enabler for early applications and provide a consistent traffic situation picture

12. Projects EMERALD and EMERTA EMERTA Conclusions (2/2) Initial applications must be chosen carefully Relevant procedures must be developed Responsibilities must be defined Issues of confidentiality Technical data-link issues must be closed Implement supporting ground systems Address CDTI HMI issues
