I don't want to spoil the party too much here, but the NDB/DME approach to runway 15 at BHX is, as most non-precision approaches are, offset from the runway centreline by, in this case, 5 degrees.
As mentioned by EK37, it was surprising to see so many aircraft so far to the left of the approach track, and only being fully lined up at a late stage on the approach. I am five miles out, and I was fairly alarmed to see/hear the Emirates aircraft come straight over my house, rather than in front of it like normal. However, a number of other aircraft did exactly the same.
In this case, it's entirely normal i'm afraid. Certainly not alarming. I'll also stick my neck out and say that the Emirates aircraft was exactly where it should have been, at the height it should have been.
