  The transition to a microservices-based Flow Management Data and Services
(FMDS) architecture from the existing Traffic Flow Management System (TFMS) is
a critical enabler of the vision for an Information-Centric National Airspace
System (NAS). The need to design a user-centric interface for FMDS is a key
technical gap, as this interface connects NAS data and services to the traffic
management specialists within all stakeholder groups (e.g., FAA, airlines). We
provide a research-driven approach towards designing such a graphical user
interface (GUI) for FMDS. Major goals include unifying the more than 50
disparate traffic management services currently hosted on TFMS, as well as
streamlining the process of evaluating, modeling, and monitoring Traffic
Management Initiatives (TMIs). Motivated by this, we iteratively designed a GUI
leveraging human factors engineering and user experience design principles, as
well as user interviews. Through user testing and interviews, we identify
workflow benefits of our GUI (e.g., reduction in task completion time), along
with next steps for developing a live prototype.
