Coff, beg to differ?
Runway QFU is 203 and the FAT of ILS is 208.
So, it is offset towards D141, not away from it.
My suggestion would be that this is due to the higher ground to the west of the FAT. 208 seems to coincide with the lowest of some pretty high ground.
ISTR the RADALT drops quite low when you fly this approach.
Cheers.
