The following graphic is essentially the same that was posted to the AF447 thread in September 2009. Added to it are the boundaries of the Nav. Warning Area, and a shaded circular area representing the 2,000km^2 the BEA has said they have narrowed the search field down to. A small red triangle which indicates the original calculated backtrack for the V/S using OSCAR/NOAA satellite derived current data along with the QuikSCAT satellite derived 10m wind data, has also been added.
Somewhere back in the original post there is a comment regarding why I increased the current velocity by 50%, which seems now to have been wrong as the best data analysis available to the BEA has concluded it was actually around 50% less.
