Flightradar24 – air traffic map online in the US

Flightradar24 is a progressive software that allows tracking any plane above the Earth and having an accurate minute information on it and its current and past flights. The tracker can be accessed via the Web or through mobile apps for Android or iOS-powered devices.

The service is based on the data received from the ADS-B receivers placed in different parts of the world. Starting from Scandinavian countries in 2006 as an initiative of two aviation enthusiasts from Sweden, the network developed quickly into the large coverage. However, embracing the globe is still the target to be achieved. Any owner of the ADS-B receiver can feed the system with its data, thus benefiting the wider and more precise information.

Statistics speaks for itself:

  • More than 10K ADS-B receivers supplying the data, which makes the largest global network.
  • 150,000+ flights recorded daily. For precise day-to-day figures, visit the Statistics page of the website.
  • Over 1.5 mln users connect to the service daily.
  • Professional trust: the large airlines (like Boeing, Airbus, Embraer) and other aviation companies rely on Flightradar data.
  • The app have surpassed 30 mln of downloads.

  • More than 120 states list the Flight radar app as Number 1 on AppStore.

  • Over 150 countries award as the best travel app offered on AppStore.

Flight Radar 24 – the milestones of development

The idea to customize the ADS-B receivers data into the tracking system has been first realized by two aviation lovers from Sweden in 2006. At first, only the Scandinavian countries and Central Europe were covered; yet, the network had been growing quickly. In 2009, the service performance has been boosted, while its initiators allowed all ADS-B receiver users connect to the system and thus make a contribution to the network.

A year after, the tracker’s data were used by global media to illustrate the flights’ schedule changes and aircraft movement above Europe and Atlantic during the volcano eruption in Iceland. This has inspired the interest and attracted thousands of users into the service. Today it embraces vast space, though a full global map makes another milestone to reach.

In 2014, the dramatic aircraft catastrophes brought another wave of keen interest to the tracker. When one of the Malaysia Airlines planes’ got missed and another crashed over Ukraine in July 2014, the service’s online map had a powerful boost of visitors. The Indonesian AirAsia aircraft’ disappearance later in the same year triggered another wave of interest to the tracker. The service reported a 50-times increase in users’ visiting, resulting in the temporary online access problems.

Most of the aviation radar feeding stations are created by passionate users. They place the ADS-B receivers at their homes and other locations, where the devices decode the data received from planes and send the information to the Flightradar24 server via the Internet. By the end of 2015, there were 9,000 receivers registered in the system. By that time, in November, the Guardian published the news about another aircraft catastrophe using the Flightradar24.com data as an official source.

The essence of Flightradar24.com

Primarily based on ADS-B receivers’ data, the Flightradar got developed over the time. Today, it combines the information received by radars and the preciseness of the data is boosted by the MLAT technology implementation. Both aircraft and airport data are used and constantly updated. The combination of the several data feeds allows reflecting the most accurate position of any aircraft. Depending on the destination status (“unknown” / “known”), the plane’s current location is traced within every 10 or 120 minutes. Sometimes, the mistakes happen due to the insufficient coverage or poor connection with the aircraft. Then, the biggest deviation might make a bit more than 50 miles.

The following means of tracking connection are used in the Flightradar24:

ADS-B receivers

This technology relies on transponders installed in each modern (and in some outdated) aircraft. The technology merits made for including it as a primary data feeding means in all aircraft by the year 2020. Currently, less than one-fifth of the general aviation planes is equipped with the ADS-B transponders. For passenger flights, this number is much bigger (about 70% on average), yet, still not enough for providing the full picture of the current aviation.

The ADS-B technology allows each receiver to control the territory of about 200 miles around it. It works at the high frequency of 1090 MHz, so the low signal is better caught at the higher flight. Today, there are 17K+ inland ADS-B receivers that receive and transmit the relevant signals from on board. The full coverage is present at the USA and for all the European countries. The most of South America and South Africa, Canada, Russia, the Middle East, and most of the Asian major countries (including China and Japan) have a well-established ADS-B connection, too. There might be some flaws in coverage in other countries; still, the ADS-B receivers’ worldwide system is constantly growing providing the more precise and informative data.

The mechanism of ADS-B-based tracking system goes like follows:

  • The plane’s position is defined basis satellite connection.
  • The position along with the supplementary data is sent via the ADS-B transponder onboard.
  • The ADS-B inland receiver (making a Radar24 active unit) catches the signal.
  • The receiver sends the information to the Flightradar24 service.
  • The information is reflected on the Flight radar interactive map and is read by users.

Flarm receivers

Flarm is a technology working for smaller personal aviation. These receivers can catch signals within 60 miles and are used mostly by airports with intensive glider traffic.

Multilateration technology

For the planes with the older version of transponders, the position can be calculated basis the MLAT tech. It is based on the data received from four or more receivers and the estimation of the time the signal needs to get through. This mode of data transmission can be used only above 3,000 feet height. Currently, the technology is used over Europe, North and South America, Asia, South Africa, Australia. The data received by means of MLAT is precise though features a bit more delay than ADS-B technology operation.

Radar technology

Flightradar24 is enhancing its data by means of the information got directly from radars. The major part of the commercial flights and scheduled private flights are registered by radars. This technology covers the territory of USA and Canada, as well as adjoining oceans airspace.

Tracking my airplane on FR24 – geography and airlines

Currently, the flight radar service tracks more than 32505 aircraft of different type arriving and departing from 8675 airports located in 190 countries. That makes for 960 airlines from all over the world embraced.

The current state of the Flight radar 24 coverage is reflected by the airport icons in the area. With the sufficient coverage, the icons are blue. Still, the coverage and visibility of the plane depend on many parameters such as congestion, type of aircraft, its altitude, transponder type and operation, ground landscape and so on. It might happen that two aircraft at the same location are tracked differently. Not seeing the plane you need means it is either not covered by the service currently, or its transponder is out of service / non-compatible with the Flightradar system.

What planes are tracked by the Live Flight Radar?

All the aircraft equipped with the ADS-B transponders are seen on the Flightradar 24 map. However, currently, the large passenger aviation planes are the ones maintaining the technology. At the same time, the owners and operators of the smaller aircraft tend to equip them with the ADS-B transponders, too. Besides, even the ADS-B equipped aircraft might be not visible in the area with the limited number of ground ADS-B receivers or an uneven landscape.

Some of the aircraft (ADS-B equipped) that are usually tracked by the Flight Radar24 service, are listed below:

  • Airbus – all planes
  • ATR 72-600 (the newest models)
  • Boeing (standard models from 737 to 787)
  • Bombardier CS100 and CS300 series
  • Embraer E190 (the newest models)
  • McDonnell Douglas DC-10 and MD-11
  • Sukhoi SuperJet 100

The next list consists of the aircraft not tracked by the service (mostly, not having the ADS-B transponder):

  • ATR 42 and 72
  • Boeing up to 737 and specific series (e.g. 747-200, 747SP)
  • Bombardier Dash (all planes)
  • De Havilland Canada DHC-6 Twin Otter
  • Saab 340, 2000
  • Majority of military aviation and propeller-equipped planes
  • Majority of helicopters, business, and older aircraft

Some of the listed aircraft might be tracked via Flightradar24 if the ADS-B transponder has been installed. Otherwise, some of the planes from the first list might be not seen on the map due to the insufficient coverage or ADS-B transponder being out of operation.
