Skip to comments.Shift of Earth's Magnetic North Pole affects Tampa airport....
Posted on 01/06/2011 8:52:44 AM PST by TaraP
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.
The poles shift continuously...This makes no sense...
I remember when the Tampa airport only had one little building and you had to walk outside to your plane.
Russia is stealing the North Pole?
I saw this story over at godlikeproductions and didn’t believe it. I guess it is true. Wow.
I thought those designations would be using geographical north, not magnetic north, anyway.
They probably do it only once every certain numbers of years, instead of changing it minutely every day.
Putin has a magnetic personality.
Probably for the compasses.
They have to close the runway for more than a week to repaint the numbers on it?
Is that union labor? Or government regulations?
True. It should also be noted that the speed of the shift isn’t constant. Some years its faster and other years there is little movement.
Seems to me it would make more sense to orient runways based on the prevailing winds, especially with larger aircraft. However, that may not be possible with busy, multiple runway airfields.
They (Jeppesen et al) may have to reprint a bunch of charts too.
That could explain it alright.
This is an excerpt of a longer video - he produced this to highlight this one part.

We never could trust ‘em. ;-)
Whoa...not only will Sarah Palin see Russia from her backyard...she’ll be there before you know it
Can’t wait till some wacko leftie ties this to Bush, global warming, or the new Republican House.
Oh God, man made Global Magnestism. I am applying for a $50 million research grant today!
I hope Al Gore doesn’t find out about this. He will want to spend billions trying to keep the magnetic pole from moving.
And wind up the propellor?
The FAA changes the runway headings at airports occasionally as the magnetic deviation increases. For incidence, I attended Embry-Riddle Aeronautical University in Daytona Beach in the early 80's. The runway heading for the main runway back then was 06/24. It's now 07/25. Who navigates with a compass anymore anyway?
Go to the Observatory in Greenwich site....very cool.....
PBA DC-3s- Loved ‘em. One of the steepest climbs ever was getting to the cockpit.
Just remember Sac, the Earth Variates, Man Deviates. so don’t put your pocket knife down near the compass.
Actually the drift is speeding up and has been for the last few centuries.
Interesting times ...
Maybe they freaked out over all the dead birds falling from the air...
I would post it directly, but it is over 3 MB.
I’m surprised that after so many posts, no one has spotted that this is all due to GLOBAL WARMING!!!
Nonsense, my good man. All you need do is wait until my favorite restaurant issues the new place mats. Although they are conspicuously marked "Not for Navigational Purposes" in big red letters, I have used them for years. They are plastic, so all you need do to find Casco Bay or Boothbay, or Kennebunkport is wipe off the ketchup and keep your eyes open.
What the heck are a few degrees of variation among friends? You airplane drivers are always looking for trouble where none exists.
Luckily this doesn’t affect any other airports.
Pretty much. That was when Lutz was way out of town.
I used to ride my Lambretta motor scooter out there and climb the stairs to the control tower where I would spend hours bugging the controllers with questions. It was sometime in 1957 as I recall.
They would have the aircraft parked on the tarmac for a couple of hours before flight time. There were no fences and no locked doors to prevent access to the cockpit of a plane waiting there. I would wander up and sit in the cockpit and play make believe. When the crew came to get ready I would hang around and question them until they ran me off.
Thanks for the memories!
Well, if the FAA is still using vacuum-tube electronics, I guess they're also using magnetic compasses.
On the other hand, maybe they just assume pilots are too dumb or too ill-informed to know about correcting for magnetic deviation -- in spite of the fact that magnetic deviation is one of the first thing anybody learns when undergoing basic training for map reading, surveying or navigation!
Why is it that the compass on my iPhone can give true north, but the airplanes cannot do this?
I guess that means I can forget the old saying I used when learning to fly back in the 50’s, “East is least and West is best”? And “True virgins make dull company.”
Ah, the good ol’ days!!
Who is going to move the North Star?
I thought RGO was closed about ten years ago, except as a museum. The RGO was incorporated into the NPL (British National Physics Laboratory) and moved physically out of Greenwich and then abolished. What site are you referring to as the the RGO site? BTW, the Nautical Almanac had been a joint venture of the USNO and the RGO for about a century and then the RGO dropped out and Her Majesty’s Printing Office doesn’t even publish it anymore. Shame.
Maybe it’s so the pilots have one less thing to correct for.
Once you get in northern Canada they do designate the runways using true north rather than magnetic north.
Perhaps the north pole prefers the manly Vladimir Putin to the metrosexual 0bama and it's running away.
Isn’t it really a digital readout, and not an actual compass?
Obama will claim credit for the 10 jobs this creates..
