Advanced controller support tools for sequencing and merging operations

This paper proposes the adoption of a set of ground support tools to assist the approach controller on issuing and monitoring spacing instructions where interval management operations are carried out. The algorithmic basis of these tools, based on computing feasible maneuvers to achieve the desired spacing and monitoring their safe execution, is described. These tools assume the use of suitable airborne spacing–flight deck interval management systems, and exploit them. These controller support tools comprise two phases: (i) the design of the intended maneuver, making use of simplified geometrical calculations to compute required routes and speeds; and (ii) the monitoring of the safe execution of the intended merging operations. The designed tools have been tested developing a simulator that comprises the complete process. The simulator first generates a set of feasible maneuvers to allow the controllers the selection of the most appropriate one, then simulates the selected maneuver and secondly monitors it to ensure safety and correctness of the operation. The simulation takes into account inaccuracies such as inexact weather (wind) forecast and errors in Automatic Dependent Surveillance – Broadcast measures.
