The airport has closed its primary runway until Jan. 13 to repaint the numeric designators at each end and change taxiway signage to account for the shift in location of the Earth's magnetic north pole.
The closure of the west parallel runway will result in more activity on the east parallel runway and more noise for residential areas of South Tampa.
The busiest runway will be re-designated 19R/1L on aviation charts. It's been 18R/36L, indicating its alignment along the 180-degree approach from the north and the 360-degree approach from the south.
Later this month, the airport's east parallel runway and the seldom used east-west runway will be closed to change signage to their new designations.
The Federal Aviation Administration required the runway designation change to account for what a National Geographic News report described as a gradual shift of the Earth's magnetic pole at nearly 40 miles a year toward Russia because of magnetic changes in the core of the planet.
Why Tampa? Why NOT Atlanta? Or why not anywhere else...
ping - why Tampa and not Atlanta?
Because Savannah INTL changed theirs in 2009.

Thx 4 the ping.
I have no idea.
Will check the post.
Ah, a voice of reason finally.
As an electrical engineer with my specialty being RF, who is also a pilot, this is something that crosses my mind every time I enter controlled airspace.....
Um, might wanna get a new calendar... ;-)
(kidding)
LOL!
Nice example. Crosswind must be a real dog there ...

Well, at least those old-fashioned “valves” have a few advantages.
Here’s what comes to mind, in approximate order of importance from high to low:
1. If you live in a northern clime, they help keep you warm in winter.
2. Some musicians think they make guitar amplifiers sound better.
3. Some audiophiles prefer them for their “hi-fi” equipment.
4. They don’t contribute to depletion of the world supplies of gallium arsenide, silicon carbide and germanium.
5. They offer partial protection against EMP.
So let’s not complain too much!
