Flightradar 24 has a rapidly growing network of several thousand ground stations around the world to receive this data that then shows up as aircraft moving on a map in the app. In an expanding number of regions Flightradar24, with the help of multilateration, is able to calculate the positions of aircraft that dont have ADS-B transponders. Traditional radar data is also used in the app thanks to a direct feed from the US Federal Aviation Administration (FAA). This data provides near real-time coverage of all US and Canadian airspace.Visit http://www.flightradar24.com for more information.Please note that coverage will vary.CONNECT WITH FLIGHTRADAR24Like us on Facebook and follow us on Twitter for the latest on Flightradar24.HELP & SUPPORTPlease visit the Flightradar24 forum for help and support.http://forum.flightradar24.com/threads/89-Important-Read-this-before-you-ask-questionsDISCLAIMERThe use of this app is strictly limited to entertainment purposes.
