Multiple Choice

Which airport uses the runway pair 5/23 and 18/36?

Runway numbers show magnetic direction. They’re the compass heading of each end, divided by 10. So a runway labeled 5/23 points about 50° in one direction and 230° in the opposite direction. The other end, 18/36, points about 180° and 360°. Having both runways labeled this way means the airport has two runways roughly perpendicular: one NE–SW and one N–S. Greenwood airport (KGWO) is the airport that has this exact pair of runways, 5/23 and 18/36, matching the description. The other airports listed don’t share this specific runway layout, so they aren’t the correct match.
