Websites that offer live radar flight trackers include FlightAware.com, PlaneFinder.net and FlightRadar24.com. These websites also offer mobile device apps that provide flight status and location data as well.
One popular flight tracking service is FlightAware, which provides flight tracking information on public and private aircraft, as well as airport delay data, weather maps and navigational charts. FlightAware offers an app for flight tracking and other travel data for iOS, Android, Windows Phone and Windows. FlightAware has also released a library of open source software, including a package that allows hobbyists to build their own flight tracking database stations using readily available, inexpensive hardware.
PlaneFinder.net offers real-time flight tracking on the Internet or through an app for mobile devices. The real-time data on PlaneFinder.net comes from the ADS-B tracking system present in most commercial airliners that rebroadcasts the plane's GPS location. Radar tracking data from the FAA is also available, but is restricted by law to a minimum delay of five minutes.
FlightRadar24.com offers consumers another service for flight tracking that displays color-coded flights using either real-time ADS-B data or time-delayed FAA data. The service is available through the company's website, on iOS and Android mobile devices and on Mac and Windows computers. The service also provides detailed information on individual airlines and airports.
