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

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
