Flightradar24 shows live air traffic, from different parts around the world. The technique to receive flight information from aircraft is called ADS-B. That means the Flightradar24.com can only show information about aircraft equipped with ADS-B transponders. Today about 60% of the passenger aircraft and only a small amount of military and private aircraft have an ADS-B transponder.
Flightradar24 has a network of about 250 ADS-B receivers around the world that receives plane and flight information and sends this information to a server, and then displays this information on a map. At the moment, Flightradar24 covers about 90% of Europe. There is also some coverage in USA, Australia and Middle East.
