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 of the Network Management functions (2)
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+

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

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.

Shortcomings:
• Lack of Airspace management flexibility
• Missing capacity opportunities
• Unnecessary protections

• Area with defined lateral/vertical dimensions + time allocation.
• At variable geographical location along the trajectory, activated
& de-activated during specific timeframes to protect an activity

• Lack of flexibility in Flow Management
•Lack of accuracy with Hourly counts
•No measure at and after departure
• Overprotections
• Reduced Nw performance
