Presentation Outline
• Methodology
• Summary of Data Assessed
• High-Level Overview
• Focused Review of Selected Sites
• General Findings
3
Methodology
• Selected sample data representative of the four seasons
from the MWAA noise monitoring system
• Focused on early morning and late night hours
• Assessed individual noise events from aircraft operating
at DCA recorded at each of the monitors:
– Maximum noise level (Lmax)
– Type of operation (arrival or departure) and runway used
– Aircraft type
– Airline or operator and flight number
4
Noise Data Assessed
• Monday, Wednesday, and Saturday of four
representative weeks in 2016:
– January 11, 13, and 16
– April 4, 6, and 9
– July 4, 6, and 9
– October 3, 5, and 8
• Early morning and late night hours:
– Early morning: 5 a.m. to 7 a.m.
– Late night: 10 p.m. to 1 a.m. of the following morning
• Approximately 65 to 68 percent of the assessed data
reflected North Flow conditions

Generalized Findings
Overall Noise Levels and Noise Events
• Data from NMTs along the river show comparable noise
levels on both sides for the majority of sites, suggesting
general adherence to the river course
• Deviation begins to the north near the Cabin John site
due to locations of NMTs and turns off of the river course
• To the south, noise levels are similar on both sides
although the numbers of events recorded is higher to the
east likely due to predominance of North Flow during the
assessment period and the final approach course
26
Generalized Findings
Individual Aircraft Noise Levels
• Departures and arrivals produced similar ranges of Lmax
values at the various NMTs
• No aircraft type appeared to be the greatest culprit,
producing the highest Lmax*
• Lmax values of some regional jets (e.g., Embraer
170/175) were in the same range with mainline jets
(e.g., 737, A320)
• The highest ranges of Lmax recorded at each site did
not represent the majority of recorded Lmax values
*Note that very few events from MD-80s were recorded due to the hours assessed and the penalties associated with their operation during
early morning and late night hours.
