ABSTRACT
Subjective data included results comparing a simplified model of Conflict Alert to the three T-TSAFE conditions. The controllers reported that they experienced similar levels of workload, with a slight increase in the physical component of the workload in the condition that required the controllers to make commanded altitude entries via the keyboard. The subjective data on the procedures were favorable towards T-TSAFE over Conflict Alert. The controllers found that they maintained better awareness of potential conflicts and had adequate time to act on the alerts with T-TSAFE. They also reported the T-TSAFE procedures as more acceptable and easier than those with Conflict Alert. Further human in the loop testing of the tool with longer run durations is necessary to better understand the impact of altitude entries on the overall performance of the conflict detection and resolution tool.
