The runway number is displayed on which part of the airfield?

• A. Centerline
• B. Approach
• C. Threshold
• D. Taxiway

Answer: (B)

Runway numbers are a visual cue tied to the direction you’re landing from. They’re painted on the runway surface at the end you approach, so they’re easy to read during final approach. Seeing the number as you approach helps you confirm you’re lining up with the correct runway and know the exact heading you’ll be flying toward that runway. The numbers aren’t related to the centerline, taxiways, or other parts of the airfield; their purpose is to identify the runway from the approach path. So the display is on the approach end of the runway.
