If you are a first time user, please take a moment to read the information below, to familiarize yourself with what AirportMonitor does, and how it works.
If this is your first time using AirportMonitor, we recommend that you first read the material on this page to familiarize yourself with how it works. If you choose to bypass this page, you can always access the help page on AirportMonitor
Using (STL) AirportMonitor
AirportMonitor shows the flight tracks of aircraft arriving and departing to and from (STL), and from other airports throughout the region. It also shows aircraft transiting through our airspace.
The size of the airplane icons is the same regardless of which type of aircraft it represents. At closer zoom levels, the size of the plane icon is larger than at wider zoom levels, to make the screen easier to view, and to simulate the effect of a changing “bird’s eye view.”
Helicopters are usually represented by black helicopter icons, although they may also show as a black airplane icon instead.
The default view for AirportMonitor is “Current,” which is the actual flight activity around (AIRPORT CODE OR NAME), with a 10-minute delay for security.
When you click on a flight in “current” mode, it will display SOME of that flight’s identification (limited in current mode for security):
When you click on “Pause”, it will pause the display for viewing. You can click on any plane icon while in pause, and it will display the available flight information. Clicking “Restart” will pick up the flight tracking where you left off (to get back to the current time, hit “Current”). Pause and Resume work in both Current and Replay modes.
Replay Mode Speed
In Replay Mode you have the option to choose the speed of the aircraft on your screen. This is useful for "fast-forwarding" to a flight or track of interest without waiting for it to appear in real-time. First choose the date and time of replay; then select the playback speed you desire; then click on "replay". You can also adjust the speed of playback after you are already in replay mode.
You also have the option to in Replay Mode – it works exactly the same way as it does in “Current” mode. (see above)
In addition to the 10-minute delay in “current” mode, AirportMonitor has other filters designed to enhance security or, in a few select cases, protect privacy.

A Word about Radar
Aircraft tracking radar, and the software that supports it, while highly reliable, is also complex. Sometimes circumstances can interfere with the signal, causing temporary distortions. For example, you will probably notice that an aircraft flying directly over (STL) may temporarily disappear from the screen and then reappear away from the airport. This is due to the aircraft passing directly over the radar antenna and the temporary loss of signal. You may also notice aircraft icons sometimes “dropping off” and/or suddenly doing unusual things. This is especially true in the area immediately around (STL), but could also occur away from the airport as well. These “ghost” aircraft are due to radar reflections around the airport, and possibly from terrain and meteorological conditions farther away from STL).
