Dry Runway Notation: Which statement accurately describes the notation 4000'x70'?

• A. Runway length is 70 feet and width is 4000 feet
• B. Runway length is 4000 meters and width is 70 meters
• C. Runway width is 4000 feet and length is 70 feet
• D. Runway length is 4000 feet and width is 70 feet

Answer: (D)

Reading runway notation 4000'x70' means the runway is 4000 feet long and 70 feet wide. The first value before the apostrophe is the length in feet, and the second value after the x is the width in feet. The apostrophe indicates feet, so units aren’t meters here. So this describes a runway that is 4000 feet long and 70 feet wide. If the numbers were swapped or if meters were used, that would describe a different dimension.
