1 DIS/ATD ASA Programme/ Conflict Detection and Resolution Automated Support To ATS Programme FAA/EUROCONTROL TIM 6 Memphis,

2 DIS/ATD FAA/EUROCONTROL TIM 6; ASA PROGRAMME; Today * Short introduction to Automated Support to ATS Programme (ASA) * Medium Term Conflict Detection (MTCD) * Conflict Resolution Assistant

3 DIS/ATD FAA/EUROCONTROL TIM 6; ASA PROGRAMME; Automated Support to ATS Programme ASA

4 DIS/ATD FAA/EUROCONTROL TIM 6; ASA PROGRAMME; Operational improvement * Expected improvements:. use of automated tools to assist the controller in planning and tactical decision making. redistribution of control tasks within sector teams or a control centre. transfer of some separation tasks to cockpit

5 DIS/ATD FAA/EUROCONTROL TIM 6; ASA PROGRAMME; Implementation * Implementation dates do not always need to be identical throughout ECAC area * Two types of implementation must be exploited in the Strategy:. Initial Operation Capability (IOC) - to provide early benefits for the stakeholders. (perhaps in ). Full Operational Capability (FOC) - achieved when all of the ATM units expected to implement an improvement are able to do so. (around )

6 DIS/ATD FAA/EUROCONTROL TIM 6; ASA PROGRAMME; Automation levels * Initial automation. controllers routine tasks that provide information for decision making * Enhanced automation. improves controllers problem detection and resolution activities. integration of information management to support decision making

7 DIS/ATD FAA/EUROCONTROL TIM 6; ASA PROGRAMME; Automated Support to ATS * ASA Programme * Operational Requirements and Functional Specifications * Feasibility and Cost-Benefits * Algorithms, Demonstrators

8 DIS/ATD FAA/EUROCONTROL TIM 6; ASA PROGRAMME; ASA Functionality * Arrival and Departure Management * Medium Term Conflict Detection * Conflict Resolution Assistant * Safety Nets. Short Term Conflict Alert. Minimum Safe Altitude Warning. Area Proximity Warning * Improved information management * Multi-Sector Planning. e.g. Traffic Load Smoother, Trajectory Editing

9 DIS/ATD FAA/EUROCONTROL TIM 6; ASA PROGRAMME; Conflict detection and resolution * Is the core task of ATC * Facilitated now by strictly constraint procedures (e.g. fixed-route networks) * This will change with free routes/free flights concepts

10 DIS/ATD FAA/EUROCONTROL TIM 6; ASA PROGRAMME; Medium Term Conflict Detection MTCD I couldn't repair your brakes, so I made your horn louder.

11 DIS/ATD FAA/EUROCONTROL TIM 6; ASA PROGRAMME; EATCHIP Phase III MTCD * Is a planning tool and does not lend itself easily to tactical controller use although modification is possible * detection is only done on the planned trajectory (and all updates), tactical trajectory as a separate entity from the planned trajectory, was not considered * algorithms are based on geometric detection, uncertainty is modelled separately and taken into account within the MTCD * detection is done based on segments that are derived from the trajectory data * Amsterdam ACOD as a basis

12 DIS/ATD FAA/EUROCONTROL TIM 6; ASA PROGRAMME; Some problems with trajectory * How to close an open trajectory?. intermediary Cleared Flight Level (climb and descent). heading instructions. speed instructions * How to ensure that ATC clearances are in the system? * How to model uncertainty and transfer * Perhaps there is a need for two separate trajectories; planning trajectory and tactical trajectory?

13 DIS/ATD FAA/EUROCONTROL TIM 6; ASA PROGRAMME; MTCD tools {Compilation of Pictures of MTCD simulation tools here Talk to Bob}

14 DIS/ATD FAA/EUROCONTROL TIM 6; ASA PROGRAMME; EATCHIP 3 simulations Phase 1 Create HMI baseline Phase 2 SYSCO&Civil/Mil Phase 3 MONA MTCD SNET Phase 4 AMAN EATCHIP III Demonstrator STD FS OR/FS OR Results Review Spring 97 Review Winter 1998/99

15 DIS/ATD FAA/EUROCONTROL TIM 6; ASA PROGRAMME; EATCHIP-3 MTCD context

16 DIS/ATD FAA/EUROCONTROL TIM 6; ASA PROGRAMME; MTCD Simulations in Brétigny * November Problems with trajectory prediction and clarity of concept of operation. Controllers had some problems in accepting MTCD tools * December New trajectory predictor. New concept of operations. Display of context aircraft. New/updated HMI tools

17 DIS/ATD FAA/EUROCONTROL TIM 6; ASA PROGRAMME; Conflict Resolution Assistant CORA

18 DIS/ATD FAA/EUROCONTROL TIM 6; ASA PROGRAMME; CORA Project * One of ASA activities * Addresses all three levels of CORA functionality * Project Organisation. Operational Requirements and Data Processing Team (strategy). ASA Programme Steering Group (action plans). CORA Advisory Task Force(work plans and technical consultation) * Project runs from now until about 2008 Whenever things sound easy, it turns out there's one part you didn't hear. - Donald E. Westlake...

19 DIS/ATD FAA/EUROCONTROL TIM 6; ASA PROGRAMME; Conflict resolution phases * CORA tools will have to provide assistance to controllers resolution of the following tasks:. Planning. Resolution implementation. Conflict monitoring and re-assessment. Conflict situation review

20 DIS/ATD FAA/EUROCONTROL TIM 6; ASA PROGRAMME; Resolution phases

21 DIS/ATD FAA/EUROCONTROL TIM 6; ASA PROGRAMME; CORA Performance levels * CORA-1. display of detailed and filtered conflict data,. provide what-if-probing and. input of the resolution as a new basis for the system trajectory * CORA-2. filtered resolution advisories in addition to the basic capability * CORA-3. use of trajectory negotiation capabilities (ground-ground and air- ground) for optimum resolutions and. implementation of the resolutions, decisions in the cockpit

22 DIS/ATD FAA/EUROCONTROL TIM 6; ASA PROGRAMME; * what-if-probing for the controller resolutions * CORA 1 :. controller creates resolutions. CORA provides data filtering on controller request, what-if-tools, trajectory manipulation and automatic system updates * CORA 2. CORA provides ranked advisories. controller selects form a list OR creates own resolutions * CORA 3:. automatic implementation of some resolutions. ground-ground and air-ground trajectory negotiation Man/Machine task sharing

23 DIS/ATD FAA/EUROCONTROL TIM 6; ASA PROGRAMME; Resolution context Trajectory Uncertainty Conflict detection Separation standards Flight plan Controller orders Weather Aircraft performance Flow restrictions CORA constraints Resolution advisories

24 DIS/ATD FAA/EUROCONTROL TIM 6; ASA PROGRAMME; CORA-2 advisory generation * Analyses the predicted conflict situations for a planned or tactical trajectory * Decides on the resolution strategy. who to move. how to move. when to move * Provides solutions for a conflict * Ranks the solutions based on their quality * Generates an advisory to the operator. appropriate centre/sector

25 DIS/ATD FAA/EUROCONTROL TIM 6; ASA PROGRAMME; Solutions * Ranked in descending order based on their goodness * Goodness is based on criteria e.g. such as:. least track miles. least cost. least relative inconvenience, etc * Say 0-3 solutions per conflict * All solutions are based on minimum manoeuvre principle

26 DIS/ATD FAA/EUROCONTROL TIM 6; ASA PROGRAMME; Planning Horizons 0-5 min 5-20 min 20-x min Balance traffic load between the sectors Reduce traffic complexity to: –reduce number of potential conflicts, –reduce the number of required unplanned subsequent actions or –simplify subsequent actions Optimise individual trajectories Implement control actions planned for this horizon Plan actions to resolve those conflicts considered worth solving or that can be solved without ATC involvement later (4D aircraft, co-ordination) Prepare resolutions for some conflicts (e.g. within high complexity situations) Negotiate trajectory modifications with concerned flights and adjacent MSP areas through data-link Implement resolutions planned and indicated by other actors Resolve unresolved or new (i.e. unforeseen) conflicts Monitor traffic situation Manage the R/T communications Tools : Conflict Probe / Linear prediction Tactical conflict resolution Context filtering STCA, MSAW, APW Tools : Conflict Probe / Trajectory prediction Trajectory editing Conflict resolution Tools : Trajectory prediction Traffic Load Smoother Trajectory editing Conflict resolution

27 DIS/ATD FAA/EUROCONTROL TIM 6; ASA PROGRAMME; Possible levels of automation. No assistance from the computer. Complete set of advisories (action alternatives). A filtered set of alternatives offered. Only one advisory is offered. Computer executes the suggestion if the controller approves it. Allows a restricted time (countdown) for the controller to veto before executing automatically. Computer executes automatically and always informs the controller. Computer executes automatically and informs controller if asked. Computer executes automatically and decides to inform controller. Computer decides and executes automatically ignoring the controller

28 DIS/ATD FAA/EUROCONTROL TIM 6; ASA PROGRAMME; Possible levels of automation –No assistance from the computer –Complete set of advisories (action alternatives) –A filtered set of alternatives offered –Only one advisory is offered –Computer executes the suggestion if the controller approves it –Allows a restricted time (countdown) for the controller to veto before executing automatically –Computer executes automatically and always informs the controller –Computer executes automatically and informs controller if asked –Computer executes automatically and decides to inform controller –Computer decides and executes automatically ignoring the controller Workload Awareness Faith

29 DIS/ATD FAA/EUROCONTROL TIM 6; ASA PROGRAMME; Some open questions (1) * How far will we go and with what time-frame?. Level of automation. Implementation dates * Enhanced planning process –. How to transfer responsibility between tactical and planing controllers?. Provide CORA assistance also to tactical controller (VERA, same tool)? * What makes up the complexity of a conflict?. Number of aircraft? Context or resolution options? Or difficulty in delivery of solution?

30 DIS/ATD FAA/EUROCONTROL TIM 6; ASA PROGRAMME; Some open questions (2) * How does the AOC/aircraft interact with CORA? Or do they?. Feedback aircraft capability, route preference and company/aircraft operating procedures to controller when taking problem/optimisation resolution decisions?. Is there a need for a core algorithm to assure fairness to all operators and service providers?. Or are individual flights monitored to ensure that they are fairly treated? * Gate to gate considerations?. CORA should ideally work from the departure planning phase providing, if possible, a basis for a conflict free trajectory that does not need holding in the air?

31 DIS/ATD FAA/EUROCONTROL TIM 6; ASA PROGRAMME; Some open questions (3) * Is CORA Sector, Centre (I.e. multi-sector) or multi-Centre function?. System-wide optimisation – CORA without sector or centre constraints?. Impact of automated co-ordination between ground / ground and air / ground with the controller out of the loop? * How to take account of TP uncertainty?. Use the output of conflict algorithm to propose a default behaviour based on what a controller is doing (could be used to closed the trajectory e.g. radar heading with anticipation of return to navigation)? * System failure - what does this mean and how is it handled? Safeguards to cater for fallback - beware that we cannot limit the system to procedural fallback.

32 DIS/ATD FAA/EUROCONTROL TIM 6; ASA PROGRAMME; Some open questions (4) * Controller needs to understand the system processes.. Skills will need to evolve or be modified. Define situation awareness. Modifying the controllers skill-set is an issue to be addressed. Evolution towards single controller sectors (mixed planning and tactical tasks) with move towards supporting multi sector planning concept? * Airspace sector concept - a mix of actors operating in the same volume?. Is the one-controller one-airspace concept outlived its usefulness?. Issues in moving CORA to the cockpit - responsibility and certification?
