FLIGHT RADAR

  

 

 https://www.flightradar24.com/


How it works Flightradar24 is a flight tracker that shows live air traffic from around the world. Flightradar24 combines data from several data sources including ADS-B, MLAT and FAA. The ADS-B, MLAT and FAA data is aggregated together with schedule and flight status data from airlines and airports to create a unique flight tracking experience on www.flightradar24.com and in Flightradar24 apps. ADS-B [How ADS-B works] The primary technology that Flightradar24 use to receive flight information is called automatic dependent surveillance-broadcast (ADS-B).

The ADS-B technology itself is best explained by the image to the right. Aircraft gets its location from a GPS navigation source (satellite) The ADS-B transponder on aircraft transmits signal containing the location (and much more) ADS-B signal is picked up by a receiver connected to Flightradar24 Receiver feeds data to Flightradar24 Data is shown on www.flightradar24.com and in Flightradar24 apps ADS-B is a relatively new technology under development, which means that today it's rarely used by Air Traffic Control (ATC). Our estimations show that roughly 70% of all commercial passenger aircraft (80% in Europe, 55% in the US) are equipped with an ADS-B transponder. For general aviation this number is probably below 20%.

The percentage of aircraft equipped with ADS-B receivers is steadily increasing though, as they will become mandatory for most aircraft around the world by 2020. When mandatory, ADS-B will replace primary radar as the primary surveillance method used by ATC. Flightradar24 has a network of more than 8,000 ADS-B receivers around the world that receive flight information from aircraft with ADS-B transponders and send this information to our servers. Due to the high frequency used (1090 MHz) the coverage from each receiver is limited to about 250-450 km (150-250 miles) in all directions depending on location. The farther away from the receiver an aircraft is flying, the higher it must fly to be covered by the receiver. The distance limit makes it very difficult to get ADS-B coverage over oceans. On cruising altitude (above 30,000 feet) Flightradar24 covers 100% of Europe and almost 100% of the USA.


There is also good ADS-B coverage in Canada, Mexico, Caribbean, Venezuela, Colombia, Ecuador, Peru, Brazil, South Africa, Russia, Middle East, Pakistan, India, China, Taiwan, Japan, Thailand, Malaysia, Indonesia, Australia and New Zealand. In other parts of the world the ADS-B coverage varies. We are continually adding coverage all over the world via our FR24-receivers. MLAT In some regions with coverage from several FR24-receivers we also calculate positions of non-ADS-B equipped aircraft with the help of Multilateration (MLAT), by using a method known as Time Difference of Arrival (TDOA). By measuring the the time it takes to receive the signal from aircraft with an older ModeS-transponder, it's possible to calculate the position of these aircraft. Four FR24-receivers or more, receiving signals from the same aircraft, are needed to make MLAT work. MLAT coverage can only be achieved above about 3,000-10,000 feet as the probability that four or more receivers can receive the transponder signal increases with increased altitude. Most parts of Europe and North America are today covered with MLAT above about 3,000-10,000 feet. There is also some MLAT coverage in Mexico, Brazil, South Africa, India, China, Japan, Taiwan, Thailand, Malaysia, Indonesia, Australia and New Zealand. More areas will get MLAT coverage during 2015 and 2016. FAA In addition to ADS-B and MLAT data, we also get data from the Federal Aviation Administration (FAA) in the United States. Unlike the ADS-B and MLAT data that is presented in real-time, the FAA data is delayed by roughly 5 minutes due to FAA regulations. On the Flightradar24 map, all aircraft based on FAA data are colored orange. FAA data is based on radar data (i.e. not just planes with ADS-B transponders) and includes most scheduled and commercial air traffic in US and Canadian air space as well as parts of the Atlantic and Pacific Ocean. Flarm Flarm is simpler version of ADS-B with a shorter range, primary used by smaller aircraft, in most cases gliders.

The range of a Flarm receiver is between 20 and 100 km. Flarm receivers are often installed on small airports with a lot glider traffic to track the gliders around the airport. Read more about Flarm on Wikipedia Estimations When an aircraft is flying out of coverage Flightradar24 keeps estimating the position of the aircraft for up to 1 hour if the destination of the flight is known. For aircraft without known destination, position is estimated for up to 10 minutes. The position is calculated based on many different parameters and in most cases it's quite accurate, but for long flights the position can in worst cases be up to about 100 km (55 miles) off. In settings there is an option to set for how long time you want to see estimated aircraft on map.

Aircraft visible on Flightradar24 (within ADS-B coverage) When ADS-B was initially launched, it was primarily used in commercial passenger aircraft with 100+ passengers. An increasing number of aircraft including smaller aircraft types, are getting ADS-B transponders but, until ADS-B becomes mandatory it's up to the aircraft producer and owner to decide if an ADS-B transponder should be installed or not.

Common aircraft models that usually have an ADS-B transponder and are visible on Flightradar24 (within ADS-B coverage): All Airbus models (A300, A310, A318, A319, A320, A321, A330, A340, A350, A380) Antonov An-148 and An-158 ATR 72-600 (most new deliveries) BAe ATP BAe Avro RJ70, RJ85, RJ100 Boeing 737, 747, 757, 767, 777, 787 Bombardier CS100 and CS300 Embraer E190 (most new deliveries) Fokker 70 and 100 McDonnell Douglas DC-10 and MD-11 Sukhoi SuperJet 100 Some newer Ilyushin and Tupolev (for example Il-96 and TU-204) Common aircraft models that usually do not have an ADS-B transponder and are not visible on Flightradar24 (within ADS-B coverage): "Air Force One" Antonov An-124 and An-225 ATR 42, 72 (except most new deliveries of ATR 72-600) Boeing 707, 717, 727, 737-200, 747-100, 747-200, 747SP BAe Jetstream 31 and 32 All Bombardier CRJ models All

Bombardier Dash models All CASA models All Dornier models All Embraer models (except most new deliveries of Embraer E190) De Havilland Canada DHC-6 Twin Otter Fokker 50 McDonnell Douglas DC-9, MD-8x, MD-90 Saab 340 and 2000 Most helicopters Most older aircraft Most business jets Most military aircraft Most propeller aircraft Of course there are lots of exceptions from these rules. There are some older A300, A310, A320, B737, B747, B757, B767, MD10, MD11 aircraft flying without an ADS-B transponder, which make those aircraft invisible on Flightradar24 when in areas with ADS-B coverage only. But there are also some Twin Otters, Saab 340, Saab 2000 and MD-80 aircraft with an ADS-B transponder that are visible on Flightradar24 in areas with ADS-B coverage. Aircraft visible on Flightradar24 (within MLAT, FAA or Flarm coverage) In regions with MLAT, FAA or Flarm coverage most of the air traffic is tracked and visible independent of aircraft type. That includes propeller aircraft, helicopters and gliders. But as mentioned above, MLAT coverage is limited to some areas with many FR24-receivers and can normally only be achieved at altitudes above about 3,000-10,000 feet, which means that general aviation at lower altitudes may be flying below MLAT coverage.

 The FAA is in most cases not tracking general aviation flights without a flight plan. Data provided by the FAA is often missing aircraft registration information and aircraft tracked with MLAT in many cases are missing the callsign information. Blocking For security and privacy reasons information about some aircraft is limited or blocked. Coverage map [Flightradar24 coverage 2014-10-20] In areas where Flightradar24 normally have coverage, all major airports are marked with blue airport markers. Flightradar24 relies on volunteers around the world for the majority of our coverage. Find out how you can contribute and host a receiver. Please note that coverage and aircraft visibility is dependent of many parameters including aircraft type, aircraft transponder type, aircraft altitude and terrain, so coverage can be different for different aircraft, even on the same location. If an aircraft you are looking for is not visible on Flightradar24 it either does not have a compatible transponder or it's out of Flightradar24 coverage.
