- Session 4: Interoperation José M. Roca Air/Ground Cooperative ATS Programme Eurocontrol

- - slide 2 The ASAS Challenge Today How to accelerate the implementation of ASAS?

- - slide 3 Presentation Objectives Raising some key issues in order to support the discussions on users’ expectations and concerns. Issues to be addressed: –Interoperation, how does it change the environment, delays, standards, military, ATC sectors, single sky. –Objectives: transition aspects, mixed equipage, time scales, interoperability between various types of operation (e.g. military, GA, Airlines) and between ACCs (e.g. single sky).

- - slide 4 The Context Temporal –Package 1: –Packages 2/3: from 2012 onwards Operational Enviroment –Oceanic –Continental En-route E-TMA, TMA –Airport ASAS Application –ATSAW –Spacing –Separation –Self-Separation

- - slide 5 Conceptual Changes for the Future Co-operative services to air traffic, managing the flight trajectory: –Strategic organisation of traffic flows and extended levels of automation –Flight management from gate-to-gate –Enhanced flexibility and efficiency –Collaborative decision-making –Responsive capacity management to meet demand –Collaborative airspace management

- - slide 6 Issues Related to the Conceptual Changes  An essential element of these changes is  the timely open access to and availability of consistent, validated and up-to-date information about  airspace availability conditions (ATM environment),  flights intentions and their operating conditions  shared by all of those involved in their planning and execution (aircraft operators, en-route ATC, ATFM, airport ATC, and airport operators and other interested authorities). ASAS impact –ASAS is an essential tool to enhance flexibility and enable efficicency increases. –Can it reduce the quality (i.e. accuracy) of the flight intentions available for the planning? –Will it reduce or improve the ATM network predictability?

- - slide 7 Changes Further Ahead Being defined by the ACARE initiative Elements of the 2020 targets –One man cockpit –Automated Flight –Automated Air Traffic Control ASAS Issues –Will the future ASAS target only at preventing collisions? –Or will it also aim towards expediting and maintaining an orderly flow of traffic?

- - slide 8 Interoperation with system elements [1] ASAS and ACAS –at the level of procedures –at the level of systems (datalink and CDTI) Airspace Users –Business aviation will benefit of the increased flexibility and efficiency –Military Can ASAS improve access to military airspace? Datalink Technologies –Multipe ADS-B links used simultaneouly. –Multiple CPDLC links used simultaneously (ATN, FANS-1/A) –Other datalinks (ACARS, Satellite, HF datalink,…)

- - slide 9 Interoperation with system elements [2] Impact on ATC Tools –Such as: Arrival Manager, Medium Term Conflict Detection –How will the new ASAS clearances be used by these tools? Airspace Structure –Impact of ASAS on Airspace Design to improve ASAS efficiency –Will ASAS improveDynamic Sectorisation? –Will ASAS have an impact on the Multisector Planner role? –How will ASAS improve the Functional Airspace Blocks in the European Upper FIR ASAS navigation requirements –precision on the ground to improve airport operations –accuracy and reliability on the air

- - slide 10 Interoperation with system elements [3] Airports –Can ASAS reduce the CFMU “time window” by providing more flexibility and capacity? –Improvements to airport mangement and sequencing using ASAS –How will ASAS contribute to the approaches to optimise runway use AOC –Can ASAS contribute to the fleet management issues by enabling more sharing of information? –How will ASAS provide AOC with the predictability they need?

- - slide 11 Transition Between airspace types –different ASAS procedures in oceanic and continental –alredy a “problem” for CPDLC Between ASAS levels –Can ASAS applications of different levels coexist in the same airspace? –And in contiguous airspaces? –Would it be confusing for Pilots? Mixed equippage –Mandate –Segregated Airspace –TIS-B as a complement?

- - slide 12 Other Issues Environment, how will ASAS –decrease emissions (reducing holdings) –reduce noise (via less speed variations) –reduce the industrial impact Security –How can ASAS be made less vulnerable than today’s ATC? –Should ADS-B be encrypted? –Should anybody have access to intent data?

- - slide 13 Questions? It took one of the greatest minds who ever lived to design it, but it took 500 years to find a man with a brain small enough to actually go and fly it.
