3. Introduction ASAS Thematic Network 2
Sponsored by European Commission Directorate General Research 6th Framework
Three year project from April 2005
Aim: to accelerate the application of ASAS operations in European Airspace taking into account global applicability in order to increase airspace capacity and safety.
Managed by consortium: BAE Systems, ENAV, LFV, NLR, Thales ATM & Thales Avionics, EUROCONTROL (leader)

4. 5 ASAS workshops & final seminar
Objectives
5 ASAS workshops & final seminar
Malmo (Oct 2005), Rome (Apr 2006)
Glasgow (Sep 2006), Amsterdam (Apr 2007),
Toulouse (Sep 2007)
Web-based ASAS related documentation
Annual assessment of the maturity of global ADS-B/ASAS applications by ASAS-TN2 partners
Deliverables: Report ”ASAS application maturity assessment” V1 March 2006, update V & V3 due 2008

5. ADS-B Receiver ground-station
Automatic Dependent Surveillance – Broadcast (ADS-B) Mode S Extended Squitter:
Europe: In Oct 2006, 54% of flights equipped (38% in Jan 2006) of which 66% broadcasting position (53% in Jan 2006) [source: CASCADE]
Hong Kong: In Mar % equipped (32% in Dec 2005) [source: ICAO]
ADS-B Receiver ground-station

6. 12 ASAS specialists from:
Method (1/3)
18 ASAS applications:
ADS-B surveillance
Airborne traffic situational awareness
Airborne spacing
Airborne separation
Airborne self-separation
12 ASAS specialists from:
BAE systems (UK), ENAV (Italy), LFV (Sweden), NLR (The Netherlands), Thales ATM (France), Thales Avionics (France) and EUROCONTROL

7. Method (2/3) Maturity metrics scale 0 to 4 (±0.5):
Operational concepts
Benefits and constraints
Safety assessment
Procedures and human factors
Systems, HMI and technology
Transition issues
Results reviewed by selected peers from US, Europe and Australia

8. Example metric - Operational concept
Method (3/3)
Example metric - Operational concept
1 = Problem statement, identify solutions, concept generation (concept of operations)
2 = Preliminary Operational Concept Description (R&D Operational Service and Environment Description (OSED))
3 = Draft Requirements Focus Group (RFG) OSED in development (e.g. from R&D OSEDs, trials and experiments, initial OSED) – mature and in review.
4 = Consolidated OSED - Published

9. Results (1/3) - overview

10. Results (2/3) – detailed examples Highest maturity score
ATC surveillance in non-radar areas
Lowest maturity score
Vertical crossing and passing (Airborne separation)

11. Results (3/3) – maturity rates
Largest increase in maturity score
In-trail procedure
(Airborne separation)
Decrease in maturity score
Enhanced traffic situational
awareness during flight operations

12. Conclusion
Of 18 applications: 7 have total maturity scores in range out of 24,
From , 15 applications increased in maturity score (1 new), 2 unchanged, 1 decreased, overall increase 10%
