There are two types of aeroplane, Spitfires and everything else that wishes it was a Spitfire!

Media sensationalism at its best. The runway was only closed so as to repaint the markings, which included a change of runway numbers. This happens fairly often. The magnetic pole has always shifted, which is why aviation charts always include magnetic variation. We renumbered one of our runways just 5 years ago. Over 60 years, its heading had changed from 354 to 357, nothing drastic. All it would take in some cases is a minute change.

I really wish the media would drop this story! Roll Eyes

As I said in the other thread, I'm just waiting for some intrepid reporter to connect this to blackbirds. Roll Eyes

Interestingly, magnetic deviation is one of my biggest annoyances with FSX/FS9. FSX is locked into the year 2005.

If you look at more recent charts for areas like KSEA or KIAD, and you are flying a precision approach using an EFIS and a drift bug, you will quickly discover that the numbers are off in almost all cases by a degree or two, which causes you to miscorrect for the crosswind. Too bad the magnetic model can't be updated. I also prefer to use AIRAC cycles that are also rather old and outdated.
