I believe that the amount of declination changes in a given area over time, so at some point in time, it was 4degEast and in a few years it could be 5degEast, or something to that effect. Would that mean that runway headings would change over time, and runway 32 could have a heading of 340 or so at some point? Wouldn't this become odd at some point in time.
I bring this up mostly cause I just saw the giant compass on the desert floor by Edwards AFB on google earth, and I was wondering if it was done many years ago, how accurate is it now?
