Runway numbering corresponds to which bearing?

• A. Elevation
• B. Magnetic bearing
• C. Wind direction
• D. Length

Answer: (B)

Runway numbers reflect the magnetic bearing of the runway direction. They’re the heading you would use when taking off or landing, measured relative to magnetic north, and then rounded to the nearest 10 degrees with the trailing zero dropped. For example, a runway aligned about 90 degrees magnetic is labeled 09, and its opposite end, about 270 degrees, is labeled 27. This numbering is based on magnetic north, not true north, and it has nothing to do with elevation, wind direction, or runway length.
