Air traffic flow management (ATFM) is the service with the greatest strategic nature overall and involves a number of measures to accomplish the overarching air traffic management (ATM) mission. This chapter overviews some of the most important evolutionary trends in ATM/unmanned aircraft system traffic management, prioritising those which are expected to introduce the greatest changes or yield the most significant environmental benefits overall. The increase in flexibility resulting from introducing trajectory-based operation (TBO) functionalities such as real-time four-dimensional trajectory planning and negotiation processes will enable the planning of more efficient and environmentally-friendly trajectories even in the presence of unforeseen perturbations. In particular, avionics and ATM decision support system for TBO can support user-preferred optimal flight paths (intents) and limit human interventions to strategic high-level management and emergency assistance, so as to decrease the overall workload without compromising the situational awareness.
