In this paper, the authors propose a method for improving the sequencing of air traffic arrival flows through a new allocation of tasks between controllers and the flight crew. The methodology involves a new set of spacing instructions in which the flight crew is required to maintain a given spacing with respect to a specific aircraft. Experiments were conducted to assess the feasibility, benefits and limitations of the new instructions. A positive impact on controller activity and control effectiveness was seen on upstream sectors, while the downstream sectors application was problematic. This led to a refinement of the organization of roles, working method, and airspace. An analysis of the instructions and eye-fixations indicated a positive impact on controller activity, while analysis of inter-aircraft spacing on final approach showed an increase in regular spacing.
