Evolutions of the Network Management functions (1)
• 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)
The main objectives
Evolutions in SESAR WP7 and WP13 3
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 Time-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+

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.
