This is true. What I'm confused over...is they're simply changing the runway's numbers from 9/27 to 10/28. But they're not physically rotating the runway 10 degrees.
LAX is the same way...the 4 runways are parallel, but they are 7/25LR and 6/24LR. I guess there are special notes on the approach charts to alert pilots that a heading correction is necessary.
