Safe aircraft separation for the most part relies on the reliability and accuracy of the position information displayed to the controller. This is supported by navigation equipment on board the aircraft and tools, which help the pilot maintain visual awareness. By providing more detailed information to the pilot about aircraft immediately preceding and following during the descent and approach phases of flight, SESAR expects to improve flight safety and to address aspects of operational efficiency. For example, better traffic situational awareness enables the pilot to anticipate the behaviour of other traffic and to manage air traffic control constraints that could avoid go arounds in high density traffic.

The candidate solution is looking at the possibility of delegating some air traffic control activity to the aircraft using a combination of visual operations. These include visual approach, combined with visual separation, which might enable an aircraft to fly a shorter approach - thanks to the possibility of ensuring its own safe separation from the preceding aircraft in the traffic sequence using traffic information available on board. These kind of shorter approaches and reduced separations between aircraft on the same flight path lead to improved efficiency in the terminal manoeuvring area and help to maximise airport capacity.

The candidate solution goes on to address convergence between systems in Europe and the United States; such as cockpit display of traffic information (CDTI), cockpit assisted visual separation (CAVS), CDTI assisted pilot procedure (CAPP), and closely spaced parallel runway operations (CSPO).
