ARTICLE: Changes in Earth’s Magnetic Field Leads to Renamed Oakland Airport Runways
Some wise airport navigational expert decided, when the first aeronautical charts were created, to label the runways with the numbers correponding to their direction on the magnetic compass. The immutable logic was that the pilots could easily line up for landing using the alignment on the compass. It is fair to postulate that this pioneer planner assumed that using the magnetic direction would provide a permanent designation for this navigational orientation.
Evidently magnetic orientation is not stationery, as the linked article so eloquently explains. What once was 27/9 now is 28/10 and the former 29/11 has been redenominated as 30/12!
The magnetic directions have changed over time—truly moving!Share this article:
