KOAK - Oakland International Airport - Runway Number Changes
A nice newspaper article on why they changed the Runway designations at KOAK. (www.insidebayarea.com) और अधिक...Sort type: [Top] [Newest]
Runways are numbered for their magnetic heading so pilots can reference there instrumentation in the cockpit to the runway itself. when you're trying to be very accurate as you often need to be in order to miss building, terrain, and other traffic it makes sense to change the runway numbers to match the world itself as closely as possible.
So, since the actual heading is rounded to the nearest 10 deg, +/- 5 degrees is close enough for government work?
For some reason that reminds me of the adage "the most dangerous weapon in the US Army's arsenal is a green 2nd lt. with a compass".

I'm not a pilot and had no idea that runway numbers were based on magnetic rather than true readings. With the ongoing magnetic field shift, a phenomena that's been known for some time, it makes far more sense to be based on true.
Add to this .
The shift will be gradual.
so numbers may need be changed periodically !

I read some where recently that earth's magnetism is changing direction, slowly to turn by 180 degrees.
And all designating numbers may have to be reversed.
This may an advance exercise.
Though that phenomenon will take about a million years to happen .

Aside from "tradition", "we've always done it this way", or "metric over my dead body", isn't the runway designation basically an agreed-upon name to separate it from other runways? While it does convey some information, accuracy is +/- 5 deg and changing. Northern Canadian airports are numbered from true North (Eg Alert CYLT 05T/23T - of course it is difficult to maintain the numbers on the gravel & ice runway).
Aside from politics, is there a reason to renumber? If so, would there be reasons not to switch to True bearing if you were going to change anyway?
