摘要

In the en route environment, air traffic control is responsible for maintaining separation between aircraft with the assistance of many decision support tools (DSTs), such as Conflict Probe and Trajectory Predictor. Conflict Probe predicts potential airspace conflicts and notifies the controller of the impending separation violation, while Trajectory Predictor predicts more accurate aircraft position. In the Next Generation Air Transportation System (NextGen) environment, it is envisioned that Conflict Probe performance will be improved by adding more accurate aircraft and pilot intent data, better air traffic surveillance, and 4D trajectory-based operations. This paper investigates the effect and sensitivity of a proposed NextGen improvement on the Conflict Probe. A quantitative study is designed to examine integration of the text in the 4th line of the flight data block, which currently serves as an optional note field for air traffic controllers, into the en route DST to create new trajectories. The new, more accurate trajectories are compared against the original baseline trajectories to determine aircraft position accuracy improvements from the Trajectory Predictor, and false alert reductions from the Conflict Probe. The study findings quantitatively demonstrate that heading amendments increase trajectory accuracy by reducing horizontal error as much as 6.21nm, cross track error by 3.65nm, and along track error by 3.64nm on the first day. Speed amendments, noted in 4th line of the flight data block, decrease by 10.3% the overall number of false alerts generated by the Conflict Probe.
