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.
