DRAW provides the ability to preserve metering operations during adverse weather conditions by using dynamic rerouting of arrival flights and balancing arrival demand across metering fixes. The DRAW HITL simulation #2 featured a unique, two-part experiment design which focused separately on traffic management coordinators (TMCs) and air traffic controllers. This set of simulations improved upon the first DRAW HITL simulation (May 2017), collecting more data, and utilizing a design that addressed TMC/controller team technique dependencies. TMC simulation sessions were conducted October 4-6 and October 11-13, with two teams of two recently retired Fort Worth Center TMCs. The controller session was conducted October 23-27, using scenarios derived from the TMC session. Controller test participants included seven recently retired controllers from Oakland, Los Angeles, and Fort Worth En Route Centers. Two different controller-sector seating arrangements were used to effectively create two different controller teams. Differences in TMC management strategy and rerouting behavior, as well as controller team performance, were observed, validating the decision to utilize a two-part experiment design. Preliminary results indicate TMCs were able to evaluate and reroute weather-impacted arrival flights earlier with DRAW than without. (POC: Chester Gong) + Back to Top
