The increase in air traffic and a rising number of drones require a coordinated response for the European sky. The European Commission has taken first steps to overhaul and modernise the existing air traffic management (ATM) system. The Commission has mandated SESAR, a public-private partnership, as well as EUROCONTROL among others to create a truly European solution. This means strengthening a network-centric approach and selecting appropriate ATM functionalities: Synchronisation in a timely manner is key. A more efficient ATM system can reduce CO2 emissions by 6% alone. Now, this solution needs to be put into practice.
