WebTrak Flight Tracking and Noise Information System | Noise Management
Welcome to Denver International Airport's EMS WebTrak system. WebTrak is a
system that allows you to watch the movement of flights and air traffic patterns
within the greater Denver region. This flight tracking system includes specific
information about flights from DEN, Centennial Airport (APA), Rocky Mountain
Metropolitan Airport (BJC), and Buckley Air Force Base (BKF), as well as information
on air traffic transitioning through the Denver region. Information shown includes
the aircraft’s type, altitude, origin/destination airports, and flight identification.
time, historical flight and aircraft radar data originate from the Federal
Aviation Administration (FAA) ARTS radar system at the Denver TRACON facility
in Denver. The ARTS data is downloaded and processed by DEN’s Airport
Noise and Operations Monitoring System (ANOMS).
Real time data is viewed in the Live Mode and is delayed approximately 21
minutes for aviation security reasons and for system processing. Historical
data is viewed in the Replay Mode and is available up to 60 days in the past.
Noise data from the numerous permanent noise monitoring terminals (NMTs) located
in the vicinity of DEN are available only in the Replay Mode for the previous
If you are a first time user of this system, please take a few minutes to
read the “Start Here,” “Legend,” and “Help” tabs
in the upper left corner of the WebTrak site. These should assist you in understanding
the full capabilities of WebTrak and how to use it.
WebTrak is now the site you will use for filing online noise complaints. Click on
the “Investigate” tab and then click the “Show Complaint
Form.“ You do not have to identify a flight to register a complaint. Abuse
of the online complaint system will not be tolerated. We will only
accept complaints for DEN traffic.
Aircraft icons are not to scale and will change in size at different zoom levels.
Flight and aircraft radar data originate from the FAA’s ARTS radar
system. Airline, aircraft type, and airport code information is encoded in
three or four characters.

readings shown on WebTrak at the numerous noise monitors in the vicinity
of DEN are noise levels represented by the A-weighted sound pressure level
reading. A-weighted decibels, abbreviated dBA, are an expression of the relative
loudness of sounds in air as perceived by the human ear. These noise levels
represent the actual real time sound level at that location at that moment
in time, and may be the result of an aircraft flying over or near the noise
monitor. These noise levels may also be attributed to community-based noise,
such as vehicle traffic, lawnmowers, etc. or just the ambient noise at that
location. When using the Replay Mode in WebTrak, the noise events that correlate
to an aircraft operation are shown with a square icon.
is best viewed using a high-speed broadband Internet connection. A dial-up
connection may also be used but loading the application and data will be
much slower resulting in longer waiting periods, and it will not be possible
to use high levels of acceleration when replaying flights.
WebTrak requires that Adobe Flash 9, or higher, be installed on your computer. Flash should
automatically update to the correct version. If you have difficulties with
Flash then you should refer to the Adobe
Flash Player Web site. Your computer should meet the following minimum specifications:
- Windows 98 or later, or Mac OS/X
- 128MB of RAM (256 MB recommended)
- 500MHz processor (1 GHz recommended)
Internet Explorer 6+ or Firefox 2+ is recommended for Windows users, and Safari on
the Mac. Other browsers may work but they have not been tested.
intended use of this Web site is to display the general location and flow
of air traffic in the greater Denver region. WebTrak information is not intended
for navigational purposes or airline schedule information. While ANOMS processes
a large quantity of radar data with a very high level of accuracy, in a small
number of cases, flight plan and noise data may not be correlated correctly.
You may also notice aircraft icons sometimes "dropping off" and/or
suddenly doing unusual things. This is especially true in the area immediately
around DEN, but could also occur away from the airport as well. These "ghost" aircraft
are due to radar and aircraft transponder reflections from the ground, and
possibly from terrain and meteorological conditions farther away from DEN.
