Eurocockpit claims that "AF447 was 3 Nautical miles west, well en route for a 10-nm deviation to avoid wx"... So? What do you think?
I don't know that there is enough information publically available to make thinking possible. Simply going by the route map in the report, yes, there does seem to be some deviation in the 02:10 location. I'll believe that it might have been 3nm off the centerline of the track.
However, the "well en route for a 10-nm deviation" seems to be unsupportable, because we have no idea when they begain a turn, we do not know if they are still in the middle of a turn, and of course we don't know (but can perhaps guess) a turn rate.
