Live Flight Tracking

Hi,

I'm looking at tracking flights into airports over the course of a few days, and so I'm looking at GetHistoricalTrack. As far as I can tell though, this data cuts off before final approach (I'm looking at Gatwick). The last track points I have are above 3000 feet - after that, nothing. Anyone know if data is available on approach tracks, or is this as detailed as it gets? It this to do with transition onto a separate system for landing, perhaps, or is it just that the time resolution of the data is insufficiently high to show a detailed landing track?

cheers,
James

Our data quality outside of the US/Canadian airspace will generally be slightly diminished depending on the location and carrier/operator involved. Please see this page for more details on service areas: http://flightaware.com/about/faq.rvt#intl
