BirdWatch Reporting System
The BirdWatch Reporting System (BWRS) provides capabilities for designing and generating a wide variety of numerical and graphical reports. Its key features include:
- Intuitive report design, allowing users to choose data types, data fields, report layouts and custom computations
- SQL-based data extraction from a variety of data sources, including Oracle, Firebird and flat-file databases
- Rule-based integration of data extracted from different autonomous data sources
- Extraction of data from daily reports for trend analysis
- Integration with Microsoft Excel and GRADE
BirdWatch Reporting System
BirdWatch Suite
The BirdWatch Reporting System is a key component of ATAC's BirdWatch Suite, a comprehensive set of tools for data collection, analysis and reporting on aviation operational performance. The BirdWatch Suite's main components include:
- The BirdWatch Collection System (BWCS), a library of tools to collect data from a variety of data sources such as FAA ARTCC Host, Common ARTS, STARS, and ARTS IIIA computer systems
- The BirdWatch Analysis Module (BWAM), the core data transformation and processing unit, performing trajectory reconstruction, flight synthesis and flight event analysis
- The BirdWatch Reporting System (BWRS), an Excel add-in used for report design and report generation
In addition, the BirdWatch suite contains a variety of components for data management, system monitoring and data distribution.
Data Integration, Drill Down and Publishing
The BirdWatch Reporting System provides the capability to extract data from multiple, uncorrelated, distributed data sources, and intelligently combine the results. For example, using separate databases for weather data and flight data, the BWRS could determine which flights were subject to specific weather conditions. It could answer questions such as what the average in-trail separation was for flights landing at SFO between 7 and 9 AM when visibility was below 10 nmi. Drilling down through the BWRS report tables one could then find the individual flights from which the average was calculated, and by sending those flights to GRADE the tracks for those flights could be shown and even animated. With a single click of a button, a snapshot is taken and added to a PowerPoint presentation for quick publication of results.
BirdWatch Reports
The BirdWatch Reporting System can be used to generate a wide variety of air traffic control operational reports including:
- Operations counts, including airport counts, sector counts, and runway counts
- Traffic flows, showing traffic counts as a function of time, grouped in time buckets of various sizes (10, 15, 60 minutes)
- Instantaneous traffic counts, showing a moving count of traffic within sectors
- Handoff reports, showing traffic counts, flows and densities for different control positions
- Flight time, flight distance and various delay reports
- Miles-in-trail compliance, a report combining data from the FAA's national traffic management log database with flight data to determine if in-trail separation over air traffic control fixes met specified flow management restrictions (miles in trail)
- Air route utilization, for example to determine use of new RNAV and Q-routes
- Comparison of flown trajectories versus filed flightplans
Applications
The BirdWatch Reporting System is a key component of the FAA's Performance Data Analysis and Reporting System (PDARS). PDARS is a complete system for the distributed collection, analysis and reporting of operational performance data, combined with tools to analyze and improve airspace operations. Using ATAC's BirdWatch technology, PDARS collects radar flight track data from FAA's ARTCC and TRACON facilities, performs flight synthesis and analysis, and generates over 500 BirdWatch reports daily for over 300 users at 50 FAA facilities. In addition, the BirdWatch Reporting System also provides the technology underlying the reporting function of ATAC's Military Aviation Simulation Model (NASMOD).
