POET

The Post Operations Evaluation Tool (POET) is a prototype analysis system developed by Metron Aviation, Cognitive Systems Engineering, and AMT Systems Engineering under the FAA's CDM program with a focus on supporting analysis of collaborative routing problems. These include identifying areas of NAS congestion or inefficiency. It allows users to explore how the NAS functions using a variety of performance metrics including departure, en route, and arrival delays and filed versus actually flown flight tracks.

The POET server is currently installed at the ATCSCC with access to Near Real Time ETMS data. This server maintains a "rolling" 45-day data set spanning the entire NAS for ready analysis using POET. With POET, users can easily access, filter, and visualize the flight information contained in the Near Real Time ETMS database using a variety of interactive charts, tables, and geographic displays. Analysis results can be aggregated into a variety of bins including grouping by departure and/or arrival airports, filed arrival fixes, departure/arrival times, NRP/non-NRP, departure and/or arrival centers, user class, and many more. In addition to the ETMS flight data, the NCWD weather data and the operational FCA/FEA data is also integrated into POET.

Additionally, POET has built-in a collection of powerful data mining tools to assist the user in recognizing patterns and trends within the data. Some of the patterns currently recognized include circular airborne holding, arrival fix swaps, and flown routes that differ significantly from the routes filed. POET has the further capability to integrate FAA data with airline provided flight data (such as predicted vs. actual fuel consumption), when available, to give a more complete picture of what is happening in the NAS.
