  1. Network Management functionsEvolutions in SESAR WP7 and WP13 Moving Towards an Integrated ASM/ATFCM/ATS Approach Etienne de Muelenaere 20 September 2012

  2. Evolutions of the Network Management functions (1) The main objectives • Performance driven – high Airspace Users’ involvement in decision making • From airspace-based to trajectory-based operations • Strong Network View on Capacity Management • Dynamic airspace management with enhanced civil/military cooperation • Network Management up to the execution phase • Collaborative process continuously reflected into the Network Operations Plan (NOP) Evolutions in SESAR WP7 and WP13

  3. Towards Time-Based Operations • The objective: • Extending the Network Management to the Execution phase. • The milestones: • Research & Development (SESAR Step 1): 2010 – 2013+ • Deployment in operations: 2013 – 2017+ Towards Trajectory-Based Operations • The objective: • Using the accurate and shared view of the trajectory as common reference to perform Network Management. • The milestones: • Research & Development (SESAR Step 2): 2012 – 2017+ • Deployment in operations: 2018 – 2022+ Evolutions of the Network Management functions (2) Evolutions in SESAR WP7 and WP13

  4. Evolutions of the Network Management functions (3) • Business and Mission Trajectory • User Preferred Routing • Advanced Flexible Use of Airspace • Dynamic Airspace Configuration • Enhanced ATFCM Processes (DCB) • Network Operations Plan Operational Focus Areas: Evolutions in SESAR WP7 and WP13

  5. Military Mission Trajectory enables complex military operations • Military Mission Trajectory • enables complex military operations • includes ARES requests/allocations 4D Trajectories data linked and negotiated between aircraft-ATC 4D Business Trajectories Achieving Airspace Users’ business objectives Predicted Position, Altitude, time, speed Trajectory negotiation Trajectory negotiation 4DT 4DT 4DT 4DT 4DT 4DT 4DT 4DT 4DT 4DT 4DT 4DT TTA Business and Mission Trajectory (1) Improved sharing of the Demand Evolutions in SESAR WP7 and WP13

  6. SESAR Step 1 Derived 4D Profiles Shared Profile ICAO FPL Shared view of Traffic Demand All Restrictions Network Mgnt Airspace Users 4D profiles + Additional Data Business and Mission Trajectory (2) Improved sharing of the Demand (pre-departure) • Current shortcomings: • Different views of profiles • Rejections of valid FPL • Demand impredictability • Additional workload • Reduced Network performance Evolutions in SESAR WP7 and WP13

  7. TTO TTO Crew AOC TTO TTA RBT/MT TTOT TMA + y min NM Fn ATC Tolerances -x min Business and Mission Trajectory (3) Reference Trajectories (RBT/MT) => support the CDM processes in the planning and execution phases RBT/MT Revision Process The Reference Trajectory = 4D profile and tolerances agreed so far The Predicted Trajectory = 4D profile provided by aircraft systems When PT out of tolerances => CDM revision process is triggered Evolutions in SESAR WP7 and WP13

  8. User Preferred Routing (1) • Routing based on users’ business needs – No fixed route network except for high complexity areas (flight efficiency/capacity trade off). • Dynamic transition from structured area (high complexity traffic) to user preferred routing area (low/medium complexity traffic). • Step 1: Free routing inside Functional Airspace Blocks (FABs) above Flight Level xxx. • Step 2: Pre-defined ATS Routes only when and where required (part of the Airspace Configuration Process) • From 2020: Free routing from TMA exit to TMA entry.
