Alphacentauri, I actually work in Survey so understand a little about this. My main point is that if an approach was now off by 200m then surely the approach is now no longer valid and would be pulled and to put it back in would need to be re-surveyed, thusly even knowing the details and calling an ADO wouldn't assist in this matter?
Plus, once again, what does 200m matter to a VFR Pilot?
