| NEW! WebTrak
Flight-Tracking and Noise Information
Welcome to the Columbus Regional Airport Authority’s (CRAA) WebTrak
system, a leading innovative technology that allows the public to see
the general location of flights and air traffic flow in the Columbus
region. This flight monitoring system includes specific information about
flights from Port Columbus International, Rickenbacker International
and Bolton Field airports as well as information on other air traffic
operating in the Columbus region. This includes the aircraft’s
type, track, altitude, and flight identification.
Real time and historical flight and aircraft radar data originate from the Federal
Aviation Administration (FAA). Real time data is viewed in the Live Mode and
is delayed by 21 minutes to maintain aviation security. Historical data is viewed
in the Replay Mode and is available up to 90 days in the past. Noise data from
twelve permanent noise monitoring terminals (NMTs) located in the vicinity of
Port Columbus and two NMTs located in the vicinity of Rickenbacker are updated
daily and may only be viewed in the Replay Mode.
To access WebTrak click here or on the map below. For your convenience,
additional instructions have been provided below to help you navigate the
site with greater ease.
Computer Requirements
WebTrak is best viewed using a high-speed broadband Internet connection. A dial-up connection may also be used. However 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.
CRAA’s WebTrak site requires the Flash 9. Flash should automatically update to the correct version. If you have difficulties with Flash then you should refer to the Adobe product page for Flash 9. Your computer should meet the following minimum specifications:
- Windows 98 or later and Mac OS/X
- 128MB of RAM (256 MB recommended)
- 500MHz processor (1 GHz recommended)
Internet Explorer 6+ or Firefox 2+ are recommended for Windows users and Safari on Mac OS/X. Other browsers may work but they have not been tested.
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
STARS radar system in the Airport Traffic Control Tower at Port Columbus
International Airport. CRAA received permission from the FAA to connect
to the STARS system and appreciates the FAA’s cooperation in
obtaining this authorization. Radar data from the STARS system is downloaded
and processed by CRAA’s
Airport Noise and Operations Monitoring System (ANOMS) where it is
then matched to noise events at the NMTs located in the communities
surrounding Port Columbus and Rickenbacker and uploaded to the Web
site server.

Reliability of Radar Information
The intended use of this Web site is to display the general location
and flow of air traffic in the Columbus region. WebTrak information is
not intended for navigational purposes or airline schedule information. While
ANOMS processes radar data with a very high level of accuracy, in a small
number of cases, flight plan and noise data may be incorrectly correlated.
Noise Measurement
Noise measurement on WebTrak is based on the average A-weighted noise
energy from an aircraft flying over a monitor using one second durations.
A-weighted decibels, abbreviated dB(A), are an expression of the relative
loudness of sounds in air as perceived by the human ear. For example,
25 dB(A) is the approximate loudness of a person whispering in a quiet
room. For a diagram of common noise sources and the decibel levels typically
associated with them, click here. For more detailed information on decibels,
click here.
The noise measurements on WebTrak should not to be confused with the
Day-Night Average Sound Level, abbreviated DNL (or Ldn). DNL is a noise
measure used to describe (in decibels) the average sound level over a
24-hour period, typically an average day over the course of a year. It
does not represent the sound level heard at any particular time. In computing
Day-Night Average Sound Level, an extra weight of ten decibels is assigned
to noise occurring between the hours of 10:00 p.m. and 7:00 a.m. to account
for increased annoyance when ambient noise levels are lower and people
are trying to sleep. DNL may be determined for individual locations or
expressed in noise contours.
