Abstract:A knowledge-based system for scheduling arrival traffic in the terminal area,
referred to as the Final Approach Spacing Tool (FAST), has been implemented and
operationally tested at the Dallas/Fort Worth Terminal Radar Approach Control
(TRACON) facility. Two types of controller advisories are generated by FAST:
sequence number and runway assignment. The knowledge base for runway assignment
employs a set of hierarchial rules and decision logic that evaluates both
performance and workload criteria. This formulation is based on over 2,000
hours of controller-in-the-loop, real-time simulations. In the field tests,
controllers had the option to accept or reject the FAST-generated runway
assignments. Results indicate strong adherence to the advisories and increased
capacity, with no significant impact on controller workload
