DCA AIRPLANE NOISE ASSESSMENT STUDY FY 2017-DOEE PROJECT 1 WHY PERFORM THIS ASSESSMENT? NEXTGEN! • A new national airspace system transforming America’s air traffic control system from a ground-based navigation/radar system with radio communication, to a satellite-based (GPS) system • Implementation across the U.S. from 2004 to 2025 • Advantages: • minimizes voice communication • shorter routes (more direct) • greater safety • saves time and fuel • reduces ATC & cockpit workload • reduces traffic delays • reduces air pollution • increases capacity • Disadvantage: • New air traffic control routes were established over noise-sensitive areas • NextGen implemented at the Ronald Reagan Washington National Airport (DCA) beginning in 2011 2 WASHINGTON METROPLEX STUDY AREA 3 WASHINGTON, DC METROPLEX Pre-NextGen NextGen 4 FY 2017 PROJECT OBJECTIVES • Investigate noise impacts from DCA air traffic operations • Review existing data, supplemented by new investigations, document past and current airplane noise environment over the District • Review current noise abatement procedures • Identify and develop revised air traffic procedures, acceptable to the FAA, to minimize the current noise impact on the District 5 PROJECT TEAM TThhee DDiissttrriicctt --DDeeppaarrttmmeenntt ooff EEnneerrggyy && EEnnvviirroonnmmeenntt ((DDOOEEEE)) AAiirr QQuuaalliittyy DDiivviissiioonn,, MMoonniittoorriinngg aanndd AAsssseessssmmeenntt BBrraanncchh DDOOEEEE CCoonnttaacctt:: DDrr..
