Washington Dulles International Airport - Aircraft Noise
Aircraft noise, and its impact on regional communities, was a primary consideration during the airfield planning and design phase of Washington Dulles International Airport (Dulles Airport). The airfield design restricts close-in residential development by integrating: 11,000+ acres within the airport perimeter; centrally-positioned runways; 8,000 foot buffers from runway endpoints to the property perimeter.
In addition to airfield planning, the Metropolitan Washington Airports Authority has worked closely with Fairfax and Loudoun Counties to provide residents with compatible land-use protection through effective county planning and zoning. In 1993, Loudoun County was recognized as a national leader in land-use planning associated with a growing international airport when the county implemented its Airport Impact Overlay District. The Loudoun County Airport Impact Overlay District uses Aircraft Noise Contours as the basis to convey disclosure information and construction requirements for new residential units.

IAD WebTrak - NEW Noise and Flight Tracking Monitoring Public Portal for Washington Dulles International Airport
The Airports Authority owns and operates a noise and flight track monitoring system around the metropolitan Washington region. This system has been operational since 1978 and periodically upgraded. The most recent upgrade occurred in Fall 2014. As part of the new Noise and Flight Track Monitoring System, noise monitors are located along the primary flight corridors for Ronald Reagan Washington National and Washington Dulles International airports. The ability to monitor flight track position data and collect aircraft and community noise data assists the Airports Authority to better understand how airport operations may impact neighboring communities.
On January 1, 2015, the Metropolitan Washington Airports Authority launched a new Public Portal that provides public access to noise and flight track data for (IAD) Washington Dulles International Airport: IAD WebTrak
Quick Start Guide:
The ‘Quick Start’ Tabs help users access noise and flight track data, as well as submitting a noise complaint.
- Start Here: Aircraft, Map, Controls, Flight Tags and Flight Information Panels
- Investigate: About, Where, When, What, How, Complaint Form
- Legend: Aircraft Icons, Aircraft Colors, Noise Colors
- Help: About WebTrak, Map, Flights, Noise, Other (Point of Approach, Weather, Complaints)
Noise and flight track data is available as ‘Current’ or ‘Historical’. Current data is delayed ~1 hour due to system processing and security protocol requirements. Historical data may be viewed in the replay mode.
Data Sources and Dependability:
|Noise:||Displayed Noise Levels: Noise levels displayed at each monitor location are updated every second and shown as an A-weighted decibel level (dBA). The dBA levels emulate the changes in sound pressure as perceived by the human ear. The monitored noise level indicates all aircraft and community noise contributions including aircraft overflights, vehicle traffic, lawnmowers etc. Noise Monitor locations with connectivity issues are denoted as grey circles.|
|Calculated Noise Events: The Airports Authority is the first airport in the United States to implement a technologically advanced methodology, via ANOMS, to detect noise events by adjusting threshold parameters to capture Aircraft and Community noise events. The advanced methodology does not rely on a set threshold to trigger a noise event and will compensate for lower background levels experienced during the nighttime hours and in suburban neighborhoods. Although, the overall noise energy experienced at the noise monitor does not change, the advanced methodology allows the Airports Authority to better identify aircraft and community noise contributions at those monitor locations.|
|Radar:||Flight track identification and position data is commercially purchased and processed as part of the Airports Authority’s new Noise and Flight Track Monitoring System (ANOMS and IAD WebTrak). IAD operations are color coded for easy identification: Arrivals (blue), Departures (red), Overflights - not operating at IAD (green). IAD arrivals and departures are displayed relative to airport elevation which may be different than an observer’s actual location.|
|Disclaimer:||ALL noise and flight track information provided on this site is intended for general use as a public resource tool. Flight track information is intended to display the general location of air traffic in the metropolitan Washington region and should not be used for navigational purposes or airline schedule information. Data anomalies will occur due to occasional loss of commercial resources, geographic radar reflections, weather conditions etc.|

Telephone Contact Also Available
In addition to completing a noise complaint via WebTrak, citizens are welcome to voice their concerns about aircraft noise at 703-417-1204. The Airports Authority's Noise Abatement Staff is available to discuss noise concerns during business hours. Callers are welcome to leave a voicemail message after hours or on weekends.
