Preliminary assessment of interactions between TFM and dynamic resectorization

Abstract

This paper describes research involving advanced air traffic control concepts in the national airspace system (NAS). We design an experiment to evaluate the national airspace system when both advanced traffic flow management and dynamic sector resectorization are implemented. Special attention is directed at the problem of sector capacity estimation. Preliminary results suggest dynamic sector resectorization may (i) improve NAS performance and (ii) at times positively interact with traffic flow management solutions.

Preliminary investigation of trajectory prediction impact on decision support automation

“…And of course the problem is more difficult when multiple DSTs are in operation. Not only may multiple DSTs affect each other, [21] but they may be using different trajectory predictors, or a trajectory predictor in different ways (e.g., open loop to obtain an estimation and close loop to match a trajectory constraint). Some DSTs may operate at higher, more strategic levels, and there can be a cascading effect as the TP errors propagate from the tactical to the strategic levels, [22][23] and finally to the overall system performance.…”

Interactions between single-center dynamic resectorization and NextGen TFM

“…Once these are understood the next step is to configure the TFM and DAC capabilities to take advantage of the positive interactions and avoid the negative interactions. This paper documents on-going fast-time metasimulation experiments combining DAC and TFM automated decision making in the NAS [2]. We conclude the paper with a discussion of how our results relate to the greater context of DAC-TFM Our TFM prototype is the ProbTFM tool [3].…”
