Runway 27 is aligned closest to what direction?

270 degrees magnetic.

  1. 270 degrees true
  2. 270 degrees magnetic ✔
  3. 027 degrees magnetic

Why: A runway number is the magnetic direction of its centerline, divided by ten and rounded. So Runway 27 points about 270 degrees magnetic, which is west.

Huh, didn't know that: Parallel runways add a letter, L, C, or R, to tell them apart.

The dad joke
I'm terrified of negative numbers. I'll stop at nothing to avoid them.
