Missing traffic
« on: September 25, 2011, 05:38:26 PM »
Hi,
I watched Thomson 352 (G-OBYD) flight from Glasgow to Cancun take off this morning. I thought I would have a look to see if I could see it on the other side of the atlantic this evening.I couldn't find the flight and I had the aircraft in Smartview, I noticed that Airnav has poor coverage around Florida and Caribbean but I managed to see the flight on the Planefinder.net webpage in fact there was lots of aircraft that the airnav network was not picking up. Where are these other flight tracking companies getting their data from? Take a look yourself

Thanks
Gary.

ADS-B (the data source used by RadarBox and other similar systems) is not widely implemented in the USA as it is in Europe thus we have a much bigger ADS-B coverage in Europe than in the USA.

The good news is that AirNav Systems has a software, AirNav Live Flight Tracker, which had a new version released 1 month ago (version 8) which tracks flights worldwide based not only on ADS-B information (just like RadarBox) but also radar flight data coming directly from the US FAA radar system. In addition this software also tracks flights over the Atlantic and Pacific oceans.

So, and using AirNav Live Flight Tracker, you would be able to track that flight, from Glasgow to Cancun continuosly: in Europe it would be tracked using ADS-B data, in the Atlantic with positions reports and in the US with data from the US radar system.

I wouldn't trust the aircraft positions on planefinder.net.  They appear use prediction techniques to "guess" where an aircraft is positioned, rather than using actual position reports.  See this example of EZY393, landing at EGPE, whereas planefinder.net showed it heading north, many many miles out of position.
