Flightradar24

The service displays the coordinates, altitude and speed of the aircraft, and also displays on the map the distance traveled from the place of departure. If information is available in specialized sources (for example, on spotter websites), it can also display a photo, type of aircraft, its board number, airline affiliation, departure and boarding point, and a number of other information. The service records flight history.

The service works in web browsers on desktop computers, and is also available through applications for Mac OS X , iOS - ( iPhone , iPad , iPod Touch ), as well as for Android and Windows + Windows Phone 8 .

In web browsers on desktop computers, the duration of the free session on the service is 30 minutes, after which the user is offered a paid subscription to use the service without restrictions, or, after reloading the page, you can open a new session.

The web service uses ADS-B technology to track and retrieve aircraft information. An aircraft equipped with an ADS-B transponder , during the entire Mode ["S"] flight, generates and broadcasts (at a frequency of 1090 MHz) approximately every second a broadcast, open radio message that contains its current data at the time of departure exact coordinates (determined using GPS ), your current speed, altitude and other information.

ADS-B - not all aircraft are equipped with transponders , mainly passenger aircraft, while state aircraft and GA may not have a transponder.

The US Federal Aviation Administration has stated that since 2020 the vast majority of aircraft entering US airspace should be equipped with ADS-B transponders . ^[2]

At the end of 2015, Flightradar24 uses about 9000 ADS-B receivers installed around the world, which receive information from aircraft and send it to the Flightradar24 server. The vast majority of receivers are installed by volunteers at home or elsewhere and are connected via the Internet to the Flightradar24 server, where they send the received data.

One ADS-B receiver can receive information from flying aircraft at a distance of 250 to 450 km (depending on the receiver itself and the location of its antenna).

Flightradar24 covers all of Europe (including the European part of Russia; except for the Arctic regions) and the USA (except Alaska outside the vicinity of Anchorage and Fairbanks). There is also good coverage in Canada (except Northern Canada), Mexico, the Caribbean, Venezuela (except Southern Venezuela), Colombia (except East Colombia), Ecuador, Peru, Brazil (except the states of Amazonas and Para), Argentina, South Africa, Turkey (except East Turkey), the Middle East, Pakistan, India, China (except West China), Taiwan, Japan [except the Ogasawara Islands (Bonin)], Thailand, Malaysia, Indonesia, Australia (except for territories 200 km from the coast and more), New Zealand and many other countries.

If the service does not receive data from an aircraft transponder flying over the United States or Canada, FAA data is transmitted with a five-minute delay.

Due to the high range of received signals from aircraft, any volunteer who has installed an ADS-B receiver can improve service coverage in his country, and often capture a part of a neighboring state. No special permits from regulatory authorities are required for this.

Flightradar24 received the attention of the international community during the eruption of Eyjafjädlajökull in Iceland in April 2010, when many major international media (including CNN and the BBC ) used the Flightradar24 website to describe the current situation in the sky over Europe. ^{[3] [4]} .

The record number of users on the site was recorded on July 14, 2014, when hundreds of thousands of fans watched online the movement of the Lufthansa airline, which delivered the German national football team from Brazil to Berlin ^[5] .

However, in just 3 days - after the crash in the Donbass - the company's website traffic increased 50 times. This forced her to disable some services in order to increase the number of supported connections ^[6] .
