Real-time Flight Status And Radar For All US/Canada Flights

FlightAwareFor those who receive (and send) flight data from ADS-B capable devices such as the RTL-SDR dongles or have Apps for their tablets and phones, FlightAware announced on Wednesday this change to their service:

Hi from FlightAware,

After months of development, we released a large upgrade to our back-end flight tracking engine on Tuesday. Not only did the upgrade include dozens of bug fixes and flight tracking improvements, but we added a massive enhancement for US and Canadian flight tracking — the flight status and radar data is now live with no more five minute delay! Previously, the US/Canada data feed contained a five minute delay in addition to our ~30 second processing time, but now all data is less than a minute delayed from real time. In addition to the general improvement, this yields a lot of additional benefits:

  • More seamless transition between RADAR, ADS-B, and MLAT positions
  • Flights will no longer transition from “Arriving soon” to “Arrived 5 minutes ago”
  • Fewer estimated positions due to delayed RADAR data

Now that the radar data in the US and Canada is real-time, we’ll soon be enabling public MLAT data in the US, which is real-time just like our ADS-B data.

This is a major upgrade in data for folks in North America, and it will make using programs like PlanePlotter even more useful!

For those who might be interested in building their own dedicated ADS-B receiver, information may be found here. Of course FlightAware may be used as an online flight checking service just for tracking the progress of a given flight, which is in itself a lot of fun!
