1. 19-21 April 2004ASAS TN – 3 rd workshop AIRLINES/IATA OVERVIEW Needs and Considerations Anthony van der Veldt/IATA Assistant Director Safety Operations & Infrastructure, Europe Airborne Separation Assistance System (ASAS) Thematic Network – 3 rd workshop Toulouse, 19-21 April 2004

2.  Fragmented airspace (political & organisation)  Potential Data link widely unused  No common use of data sources (air & ground)  Lack of automation support  No co-operative system approach  No challenge for cost effectiveness through competition  Today’s ATC OPS infra is still based on radar tracking, voice com and ground radio beacons Actual Problems and Bottlenecks

3. Airlines Needs  Safe and efficient services from gate to gate  Contract a 4D trajectory for this services with the responsible ATM unit C-ATM  Air Traffic Management with growth capability  Co-operative Air/Ground System  Air and ground based surveillance  Oriented on best capabilities – distributed ATM system  Enhanced Safety horizon (ASAS)  Data infrastructure (voice for abnormal only)  Flow oriented functional blocks of airspace

4. ASAS Benefits (1)  Enhanced safety Common situational awareness in air & on ground  Distributed surveillance system caters for more effectiveness & capacity  Distributed responsibility will reduce controller workload  Avoids double work  Participants to focus efficiently on their assigned task  Reduction of workload in the overall process

5. ASAS Benefits (2)  Use of data rather than voice will allow automation support to be available not only for pilots but also controllers  “Congestion resistant” due to its distributed nature  Allows larger sectors, with ground controller workload focused on strategic flow management  Availability independent of ground infrastructure – world- wide  Use of global ADS-B infrastructure standards will support use of common data

6.  Simple, functional and providing benefits  Basic cockpit display of traffic information (CDTI)  enabling reception (from other a/c) and transmission of ADS-B data  CDTI integrated into the existing Flight Deck Display systems (with ACAS)  Pilots must have the CDTI in his direct field of view Avionics considerations supporting ADS-B functions

7.  It’s time for a paradigm change, Jan 2004, J. Lauterbach/DLH  Eurocontrol ADS-B CBA based on CARE-ASAS ‘Package 1’ applications, Helios, Jan 2003 Sources
