In this case I was using Mega Scenery Earth.
I should explain that I use photo scenery, or when not available, photo real scenery, because I like to fly, in the main, over places I have never seen and to get a feeling of what its like and also to and from the places I've read about in the books I read, or, even places that intrigue me from the news.
The Flight Simulator scenery from any of them is so unrealistic as to be laughable. Someone was developing three airports for China the other week, and the bloke I beta test for asked me to check them out. The airports were alright. I'm not sure how accurate they were to the real things but that wasn't what I was checking. Anyway, in flying over the surrounding areas, I realised that the P3D scenery was just as bad as it is in the rest of the world i.e. Nothing like reality and what was worse, no attempt, from what I could see, had been made to look remotely like the real place at all. To check I was right I called my wife in (who comes from China and travelled extensively there) and she said; 'It's rubbish. Chuck it.'
In fact, there had been no attempt to make the place look like China. It could have been any place in their versions of America, Europe, or anywhere really.
Hence my use of photo scenery and no yen to fly anywhere that hasn't got it.
Sorry I was off topic but I wanted to get that off my chest. To get back to it, I just want to say that with the scenery I use, the runways have always been adjusted to be where they really are and mostly that has worked out alright while using PF3, but this one was slightly off and I wondered why.
Thanks for the replies fellers. I now understand.
