This paper reports on an experiment conducted with air traffic controllers to investigate the joint use of a sequencing tool and spacing instructions to enhance the management of arrival flows. The experiment simulated two en-route and one approach sectors (total of seven positions). It was shown that sequencing tool and spacing instructions can be jointly used in en-route and in the terminal area, with high benefits particularly in the terminal area. Main benefits are: a positive impact on controller activity (earlier flow integration and relief from late vectoring) and on control effectiveness (more regular inter-aircraft spacing on final approach, a slight increase of throughput and straighter trajectories with no dispersion below 4000ft).
