FABEC operations have made substantial contributions to the development and implementation of SESAR. Firstly, the scope, objectives and road- map of both the Free Route project and the Extended Arrival Management project have been adapted according to the PCP regulation to ensure on-time implementation. Secondly, most FABEC ANSPs are participating in the SESAR Optimised Descent Profiles (ODP) activity. This activity aims at closing the efficiency gap between direct/free route airspace and the terminal area. Large-scale simulations are planned to identify new descent/arrival routing options for nine airports in FABEC.
