“…These units are assigned to the appropriate sector(s) based on the most effective distribution of traffic demand within the defined airspace. As the distribution of traffic changes over time, new sets of sectorizations can be generated at defined intervals to reflect the changes and reduce the instances of sectors being over-or under-loaded [7].…”

Flexible Airspace Management (FAM) concept offers to dynamically modify the center/sector boundaries in such way that the airspace structure is reconfigured to better distribute unbalanced traffic demands across sectors. A set of airspace design algorithms were used in the human-in-the-loop simulation to assess possible benefits of the FAM concept. In the simulation, participants were instructed to pick an algorithm-generated airspace configuration from a set of configuration options that best solved the weather-induced traffic imbalance problems in the test airspace. Participants also rated the acceptability of the airspace designs that were generated by different algorithms. This paper explores ways to objectively quantify airspace characteristics of these algorithm-generated configurations using a set of benefits and airspace quality metrics and to compare them to the participants' acceptability ratings obtained from the simulation. Both benefits and airspace quality metrics were hypothesized to correlate with the participants' ratings. The results showed that participants' selection correlated mainly with the benefits metrics, while airspace quality metrics did not play a big role.

The effect of dynamic sector boundary changes on air traffic controller workload was investigated with data from a human-in-the-loop simulation. Multiple boundary changes were made during simulated operations, and controller rating of workload was recorded. Analysis of these data showed an increase of 16.9% in controller workload due to boundary changes. This increased workload was correlated with the number of aircraft handoffs and change in sector volume. There was also a 12.7% increase in average workload due to the changed sector design after boundary changes. This increase was correlated to traffic flow crossing points getting closer to sector boundaries and an increase in the number of flights with short dwell time in a sector. This study has identified some of the factors that affect controller workload when sector boundaries are changed, but more research is needed to better understand their relationships. Nomenclature

“…In Ref. 8 the authors present an algorithm for changing the size and shape of existing sectors based on current sector loading conditions by trading sector building blocks known as Fix Posting Areas between neighboring sector boundaries. One problem with implementing these methods is that they need to identify new traffic patterns that arise from blocking weather on which to base the new sector designs.…”

A new strategy for altering existing sector boundaries in response to blocking convective weather is presented. This method seeks to improve the reduced capacity of sectors directly affected by weather by moving boundaries in a direction that offers the greatest capacity improvement. The boundary deformations are shared by neighboring sectors within the region in a manner that preserves their shapes and sizes as much as possible. This reduces the controller workload involved with learning new sector designs. The algorithm that produces the altered sectors is based on a force-deflection mesh model that needs only nominal traffic patterns and the shape of the blocking weather for input. It does not require weather-affected traffic patterns that would have to be predicted by simulation. When compared to an existing optimal sector design method, the sectors produced by the new algorithm are more similar to the original sector shapes, resulting in sectors that may be more suitable for operational use because the change is not as drastic. Also, preliminary results show that this method produces sectors that can equitably distribute the workload of rerouted weather-affected traffic throughout the region where inclement weather is present. This is demonstrated by sector aircraft count distributions of simulated traffic in weather-affected regions.
