Runway Headings
I expect that time has gone quicker than I thought but it does not seem that long ago that Heathrow changed and more recently Stansted. Given that both Gatwick & Luton are not that far away I assume they will also change?

I haven't been flying long enough to know what they were before but Gatwick is currently 259/079 (26/08) so will need another 5 degrees to get to 254 before it's changed to 25/07. That'll take quite a while methinks.

It doesn't mean that their designations will change at the same time - that would only be the case if their true headings differed by a multiple of 10° (which they don't).

exactly...look at all of the modern technology, that must have a variable magvar built into it.
What really cracks me up is when they rename the runways, and all of the associated charts, equipment, and infrastructure changes.
As a point of reference, that is how they determined seafloor spreading, the magnetic orientations in the rock across the Atlantic, when the poles flip, and according to records, it wobbles for a very short time then flips.
The Sun drives the forces, and just as magnets repel or attract, the Sun and the Earth mag poles do the same.
The Suns mag pole flipped in 2001, and the Earths and been wobbling quite a bit, so scientists look for the mag poles to flip very soon...
and no, the Sun will not rise in the West, the Earth doesnt flip, just the magnetic polarity....
Nasa simulation..
I would hope that you are not using a compass to navigate...

This thread has legs. Let's hope it doesn't 'go west'...............

Great quote on the NASA website:
"While the conditions that cause polarity reversals are not entirely predictable – the north pole's movement could subtly change direction, for instance – there is nothing in the millions of years of geologic record to suggest that any of the 2012 doomsday scenarios connected to a pole reversal should be taken seriously.
A reversal might, however, be good business for magnetic compass manufacturers."
