Interesting to know how distant. AF447 (below) had ~10,000' for currents to nudge debris yet the FDR module was within maybe 150' of the APU, THS, and CVR (though farther from the FDR chassis). Air Aisa's search depth is only ~100'. The FDR would not have flowed with current, though the tail might have depending on what we find it looks like now. However the distance between FDR and tail, and the heading between, calculated together with the current should be telling about what part touched down first, and what forward speed might have caused the distance.

Don't misconstrue. I use AF447 ONLY because despite the huge difference in circumstances between the two, debris field maps don't grow on trees, especially accidents that generate huge interest and lots of valuable images for a hungry media, so there aren't a lot to choose from. And comparisons between the two can be as instructive for their
dissimilarities as their similarities.
