Welcome to the Louis Armstrong New Orleans International Airport (MSY) Internet Flight Tracking System, AirportMonitorTMThis system allows you to watch the movement of flights and air traffic patterns within the greater New Orleans area and south Louisiana.  If you are a first time user of this system, please take a few minutes to read the following information , which should assist you in understanding and utilizing the full capabilities of AirportMonitorTM.

This service does not provide arrival or departure information.  Please visit our up-to-the minute Flight Information page by clicking here if you wish to see what time a flight will arrive or depart MSY

Using AirportMonitor

The system shows the flight tracks of aircraft arriving and departing to and from  Louis Armstrong International and from other airports throughout the region.  It also shows aircraft transitioning through the region.  The size of the icons is much larger than the aircraft they represent and are uniform regardless of the actual size of the aircraft.

  • Green aircraft icons represent departures from MSY

  • Blue aircraft icons represent arrivals to MSY

  • Black aircraft icons represent aircraft operating to or from another airport in the region, or that are transitioning through the region and bypassing local airports

  • Red aircraft icons indicates the aircraft selected for viewing

AirportMonitor reflects radar images of what is in the airspace around New Orleans.  Therefore, you will see aircraft that are not related to activity at Louis Armstrong International.   You will see aircraft from New Orleans Lakefront Airport and any aircraft that may be passing over the New Orleans area at high altitude enroute to another destination.   When at the 80-mile range, you can see aircraft as far as the Baton Rouge Regional and the Gulfport-Biloxi Airports.

These flight tracks, although taken from actual raw radar data, are not in real time.  There is a delay of approximately ten minutes as indicated by the date and time located in the Date/Time box located in the Flight Information fields on right side of the screen.   This delay can be useful if you notice an over flight of your neighborhood and you need time to bring up the Internet Flight Tracking System to find out the identification of the aircraft type and its altitude.

In the 10-minute delay mode you will see the following information about that particular flight displayed in the Flight Information fields on the right side of the screen:

  • Aircraft Type

  • Altitude

Please be aware that the Flight Information for general aviation aircraft flying under Visual Flight Rules will not display aircraft identification information in the Aircraft Type field, due to the nature of the data transmitted by their transponder.

Just under the map you will notice 5 buttons with corresponding zoom settings ranging from 5 miles to 80 miles.  In order to change the view, just click the button corresponding to the map setting you wish to view.

Flight Tracks Replay Function

The Louis Armstrong International Airport Internet Flight Tracking System has a replay function that archives flight track data for 3 months.  This allows you to log on to the system anytime during the 3-month period and view past flight tracks.  This replay function will be useful if an aircraft over flew your neighborhood and you were unable to log on to the system within the 10-minute delay period to view the flight tracks, or if you wish to view additional information about the aircraft.

To operate the replay, use the pull-down menus at the top of the page and enter the corresponding date and time you wish (using the 24-hour clock system), and then press the Start Replay button.  The end the replay and return to the 10-minute delay mode, press the Current button.

In the replay mode (after an hour's delay for security reasons) you will be able to view:

  • Airline/Flight ID, tail number or radio call sign (for General Aviation Aircraft flying under Instrument Flight Rules)

  • Airport of Origin

  • Destination Airport

This will be in addition to the data displayed in the 10-minute delay mode.

The information contained in some of the data fields is encoded to conform to standard FAA contractions (or shorthand).  If you wish to decode the information in the Flight ID, Aircraft Type, and Origin and Destination fields please click on the following links:

A Word about Radar

Aircraft tracking, using secondary surveillance 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 over MSY will 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.  This is known in the industry as the cone of silence.   You may also notice aircraft icons sometimes "dropping off" and/or suddenly doing unusual things.  This is especially true in the area immediately around MSY, 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 high-rise buildings around the airport, and possibly from terrain and meteorological conditions farther away from MSY.

System Requirements

  • AirportMonitor is data intensive and is best-viewed using broadband or high speed Internet access.  If you are using a dial-up modem, the site will be slow to load.

  • AirportMonitor is designed to run on any computer that runs Java Applets and JavaScript.

  • A reasonable amount of memory is necessary (a minimum 64 MB or RAM is recommended), but nothing greater than what people usually have for basic word processing applications; AirportMonitor uses much less memory than the capacity of most new computers.

  • AirportMonitor runs best in Netscape or Internet Explorer versions 3.0 and greater.  JavaScript and Java must be enabled.

  • AirportMonitor is a resource intensive application that is best run without too many other applications at the same time.

  • The optimal screen resolution for viewing this site is 1024 x 768.

  • This site will not work with WebTV.
