Hi,
I did find this:
(p.68 english copy)
up to the last automatic position point, received at 2 h 10 min 35 s, the flight had followed the route indicated in the flight plan,
In waiting a translation from the original .. this is a Google translation of a extract:
For example, page 48 of the BEA report, it shows "the last position received" of 2.98 ° (2 ° 58.8 ') north and 30.59 ° (30 ° 35.4') west to 2:10 UTC.
On a map, it can easily be carried as part of the "route to the flight plan" between "ORARO and TASIL.
Between these two points, the course "right card (straight between two points on the card) is similar to circle route (corresponding to the curved line between those two points on the earth sphere). Indeed, the distance between these two points is only 119 Nm and the "arrow" (lateral deviation between the right map, and circle) is negligible over such a short distance.
The report of the position of flight AF 447 to 2:10, with the coordinates provided by the BEA, place the aircraft at about 2.9 nm west of the road.
For the curious, an official Jeppesen electronic road can be checked easily graphically.
A calculation of spherical trigonometry mathematical and precise, we wish to provide for some having doubts, gives a gap approached 2.9439071 Nm The maximum error of the accuracy of the values of position given by the BEA is 0.5 tenths degree, in one way or the other.
In other words: at 2:10, Flight AF 447 is not on the planned route in the flight plan ", as the BEA, but almost 3 Nm to the west of it.
Bye.
