Harris Statement The Symphony NextGen data is being provided to the DAL Noise office as the flight track surveillance input into EnvironmentalVue DAL s primary flight track analysis and noise management application. EnvironmentalVue is designed to increase understanding and provide complete transparency about DAL aircraft operations and their overflights in the vicinity of the airport. It does this by employing comprehensive analytics and display capabilities of the historic NextGen flight surveillance data that is collected by the system. Tracking aircraft is an intricate, intensive and, unfortunately, imperfect process. The performance and accuracy is a function of many things including the airports surveillance system/sensors, its tracking software, what type target is being tracked, and where it is being tracked. As with all surveillance systems, it is important to recognize that there are inherent limitations. Some of these limitations include interference of signals which can lead to a reduction in the accuracy of reported aircraft locations. There may also be ghost aircraft, which can be caused by interference from weather, transponder reflections from tall buildings, poor signals from the aircraft, or an aircraft s position in relation to the surveillance source. In addition, not all aircraft have identification information and some are occasionally misidentified based on the track quality, the aircraft type, and operator of the aircraft. In summary, flight tracking anomalies do happen due to factors that are often very hard to mitigate. But these anomalies are more the exception, than the norm with the EnvironmentalVue system and NextGen data.
Action Items Discuss with FAA initial heading of 135 for RNAV to DRSET Submitted to FAA for consideration - Closed Request HMMH answer community member questions. No questions submitted - CLOSED Request that DAL meet with Chief Pilot of Med Flight to discuss PRP Companies informed of PRP - CLOSED Provide a graph depicting raw data regarding runway utilization. Part of this presentation CLOSED Request information regarding airline schedule demands between 2100-2200. Part of this presentation - CLOSED Investigate the accuracy of flight tracking. Statement from Harris - CLOSED
