    It happens all the time as the poles shift. Runways are numbered based on the closest 10 degrees magnetically. So as the pole drifts they get changed.

    See wiki article on runways for details.

    ATS has a good thread on it as well.

    I'd post links but I'm on my phone.
     
  3. The notice of the day is that Tampa Airport is closed due to an aceleration in the magnetic pole shift. :cool:

    Let me see the wiki. I will contact you again if I have more doubts. Thank you Mike.

    The north pole drifts pretty randomly.
