Building a Time-Based Flow Management Performance Dashboard

This paper describes the initial development of a real-time, NAS-wide Time-Based Flow Management (TBFM) performance dashboard that aggregates relevant timestamps by flight; reports flight-specific TBFM assigned departure delay and flight-specific compliance to TBFM scheduled departure times; and presents actionable airport-level alerts (with supporting flight-specific information) based on those delay and compliance metrics. This research found that it is feasible to use System Wide Information Management (SWIM) data for real-time TBFM metrics calculation for performance monitoring and alerting. Using the processing method described in this paper, raw TBFM SWIM data was parsed and analyzed to produce operationally meaningful flight-specific timestamps, which were then compared with known timestamps in TBFM post-operations data. Validation of the timestamps supports that TBFM SWIM data can be employed for calculation of real-time TBFM metrics. Initial metrics developed along with a demonstration capability for monitoring and alerting NAS-wide TBFM departure performance are described. Notional example use cases are discussed as well as recommendations for next steps.
