ASAS TN Implementation Strategy Tony Henley BAE SYSTEMS ASAS TN Third Workshop, 19 -21 April 2004, Toulouse
Overview • ASAS-TN WP 3 Recommendations – Datalink – Applications – Implementation • The Way Forward – Local implementations • beneficial subsets of package 1 – Progressive introduction of package 2/3 ASAS TN Third Workshop, 19 -21 April 2004, Toulouse
Datalink In Europe, the initial deployment of ADS-B will be based on Extended Squitter with VDL 4 providing regional implementations and a dual link capability where necessary. Is 1090 ES a long term solution? ASAS TN Third Workshop, 19 -21 April 2004, Toulouse
Applications. Requirements Focus Group It is essential that the RFG brings together the experience and knowledge from individual research programmes in order to define a common set of ASAS applications along with the associated safety and interoperability requirements. As Soon As Possible! ASAS TN Third Workshop, 19 -21 April 2004, Toulouse
ASAS Validation activities ASAS validation work should be co-ordinated within Europe across the SEAP, C-ATM, LAVA and other programmes using where appropriate the MAEVA methodology. Need to validate safety and user acceptance, operational benefits and security ASAS TN Third Workshop, 19 -21 April 2004, Toulouse
Applications (1) Consider the Surveillance in Non Radar Airspace (ADS-B-NRA) application for early implementation. But this will not address the European capacity problem for 2010 -20 ASAS TN Third Workshop, 19 -21 April 2004, Toulouse
Applications (2) Consider the Airport Surface Surveillance (ADS-B-APT) application for early implementation. Main benefit as a ‘gap filler’ for existing/ planned multilateration installations ASAS TN Third Workshop, 19 -21 April 2004, Toulouse
Applications (3) Implement Enhanced Sequencing and Merging (Spacing) ASPA-S&M as early as practical because it will provide significant benefits to all stakeholders. Reduced controller workload. More regular traffic flows, Increased capacity ASAS TN Third Workshop, 19 -21 April 2004, Toulouse
Implementation (1) Develop a retrofit solution for equipping existing aircraft. High rates of equipage can only be achieved by equipping existing aircraft ASAS TN Third Workshop, 19 -21 April 2004, Toulouse
Local Implementations • Beneficial subsets of package 1 • • Non Radar area surveillance (ADS-B-NRA), Airport Surveillance (ADS-B-APT), Spacing (ASPA-S&M), (On Board Situation Awareness on airport surface (ATSA-SURF)) • Small numbers of aircraft • high local density • retrofit avionics • global interoperability ASAS TN Third Workshop, 19 -21 April 2004, Toulouse
Issues • • • Minimal change to ground infrastructure No change in separation responsibility Manoeuvre ‘advisor’ computation function Manual control of manoeuvres via autopilot No changes to ACAS Funding/ incentives ASAS TN Third Workshop, 19 -21 April 2004, Toulouse
Implementation (2) The preferred implementation in the long term of ASAS applications is expected to be within a fully integrated, dual redundant avionics system. Reduced pilot workload. Integrated displays Appropriate levels of integrity ASAS TN Third Workshop, 19 -21 April 2004, Toulouse
Next • Full package 1 ? • Package 2/3 ? ASAS TN Third Workshop, 19 -21 April 2004, Toulouse
