1 1 Paradigm SHIFT Eurocontrol Experimental Centre Innovative Research June, 2005 Laurent GUICHARD (Project Leader, ATM) Sandrine GUIBERT (ATC) Khaled BELAHCENE (Math Mod., Airspace) Didier DOHY (ATM, System) Jean-Yves GRAU (HF)

2 Goals To investigate a new control paradigm that could cope with future air traffic demand of the horizon 2020 and beyond. AirPorts Capacity Safety Airlines Performance Air Efficiency Navigation system Cost ANS 2 Ponctuality Environment

3 3 Paradigm SHIFT : a top down approach Analysis Scare resources: we need global coordinations and negotiations (objectives) Aircrafts, Runways, Gates, Controllers Different ATC modes of operation will prevail in different European Airspace (efficiency) Each actor is responsible for his resources and knows his constraints (management by objectives) Coordinate ops modes (continuity, stability) Functional division of traffic (capacity)

4 Paradigm SHIFT : a top down approach Paradigm SHIFT Contract of Objectives A way to cope with : Arriving on time, Coordinate resources 2 main Concepts Dual Airspace Improving the ATM capacity by functional division of the traffic From Means management to Participative Objectives management 4

5 Contract of Objectives Contract of Objectives A way to cope with : Arriving on time, Coordinate resources 5 Reconcile Ground and Air phases Define objectives applicable to flight Link ATM actors together through agreed interfaces Result of the negotiation phase involving all actors Integrate flexibility to cope with uncertainties (manage disruptions) Objectives issued through a breakdown of responsibility Seeking for the best organization at a local/lower level (best view of the reality) In order to optimize resources The Contract of Objectives is the key element for the stability of the ATM system. Air Taxiing Ground Planned what is feasible and Execute what is planned Through shared Objectives

6 Contract of Objectives 1 Flight = 1 Contract of Objectives On ground Taxiing On Flight Taxiing On ground Airport TWR ANSP1 ANSP2 Approach TWR Airport Off-Block Time Take off Landing In-Block Time Control Unit Control Unit Control Unit 6 Ground-side Main objective Target Windows Target Windows Air-side (4D intervales) Target Windows = intermediate objectives Main objective

7 Target Windows Target Windows A local representation of the global efficiency Intermediate objectives negotiated between actors Create a link between planning and execution Represent the responsibility transfer Define milestones marking out traffic progress Put constraints only when necessary Destination punctuality Technical capability (flight envelope,...) TW = Global objective (arriving on time) + local constraints + disruption management Organization, Efficiency Congested en-route area (bottleneck) 7 Open room of adaptation (limit chain reaction) To Contain residual uncertainty (disruptions management) To reduce impact of action of Control on planning Resilience (reduce impact of uncertainty)

8 Air Traffic Management Organization around the Contract of Objectives Planning Phase To Elaborate the Contracts of Objectives Need a decision-making process based on : Collaboration Granularity Execution Phase To fullfill the Contracts of Objectives To Renegotiate if necessary 8 Operational Plan Contract of Objectives Target Windows Target Windows Target Windows

9 9 Planning : Operational Plan Operational Plan A Process to build Contracts of Objectives Strategic level (large scale objectives) Macroscopic approach rather than a temporal reference (granularity, responsibility) Refinement process : refining is better than redefining Collaborative & transparent mechanism involving all actors. Achieving agreement : from the expressed & agreed constraints of involved actors Integrate disruptions

10 Planning : Operational Plan Airports RESOURCES MANAGEMENT (responsability, granularity) EXECUTION Airport capacity ATM demand Objectives agreement ANTICIPATE DISRUPTIONS Rotations ATC constraints CoO 2 CoO 4 AirLines ANS Providers Decentralized Design Start to integrate the real word CoO 1 CoO 3 10 Actor preparation phase Actor publication phase and refinement Disruptions forecast (e.g. meteo forecast) time

11 Planning : Decentralized Design Decentralized Design Organisation of En-Route resources by the ANSP What is a local optimum? Tactical balance Traffic Airspace ATC: controllers, working methods and tools Airspace Traffic Safety Capacity Efficiency ATC We discuss on traffic continuity Airlines Operational Plan Airports To achieve global efficiency by reaching an agreement on interfaces (Flights consistency) Traffic Traffic Traffic By autonomous design and local organization ANSP 1 ANSP 2 ANSP 3 11 Decentralized Design = A refining local organization process based on cooperation on traffic

12 12 Execution phase Contract of Objectives Assume global efficiency by links between actors (TW) The CoO : a Link between ATCOs Interfaces between ATCOs are specified: clear Objectives and Responsibility Evolution of the ATCOs working methodes : Manage aircraft for safety first (like today) Manage the Performance of the system (ponctuality) based on objectives The CoO : a link between ATCOs and Air-crew Same vision and common objectives Responsibility sharing : Air-crew is no longer the only one responsible to achieve ponctuality

13 Execution phase Contract of Objectives Integrate global efficiency by links between actors (TW) If a Contract of Objective couldn t be achieved : Renegotiation at strategic level Allow best alternatives at a global level Ensure overall consistency (planned/reorganised operations) Need early detection Number of occurrences is a performance indicator Corrective post analysis 13

17 17 Dual Airspace Dual Airspace A way to increase capacity Managing the Cohabitation of the two sub-systems Independent operations Opacity (no shared responsability) No Intrusion Minimun impact Transition via Airlocks Districts Highways Resilience to Disruptions

18 18 Conclusion Paradigm SHIFT is a long term Top Down Operational Vision Introduction of new concepts (Contract of Objectives, Dual Airspace,...) Open a progressive evolution of the system (no big Bang) Potential Input for C-ATM and SESAME Concepts has to be Enhanced and Evaluated Enhanced reflexion on Airports, ANSPs, Airlines Proof of concept on Dual Airspace and Contract of Objectives Low Technological Challenges Air-ground data transmission Ground data sharing information to support distributed decision-making process Roles and tasks evolutions for Controllers and Pilots
