  WebTrak Flight Tracking and Noise Information System

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.

Real 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 day(s).

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.

  Noise Complaint Information

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.

Complaints for aircraft other than DEN aircraft, please contact the corresponding noise office to file your complaint

  Flight Information

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.

  Noise Readings on WebTrak

Noise 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.

  Computer Requirements

WebTrak 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.

  Reliability of Radar Information

The 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.
