Which item is NOT listed among the seven different runway markings?

• A. Centerline
• B. Threshold
• C. Runway Numbering
• D. Taxiway lines

Answer: (D)

Runway markings are a defined set of visual cues that guide aircraft on the usable portion of the runway and provide position and approach information. The standard seven include threshold markings at the start of the usable surface, the runway designator numbers at each end, the centerline that runs down the middle, the aiming point where landing should primarily occur, the touchdown zone markings in the first portion of the runway, the runway edge markings along the sides, and distance-to-go markers that show remaining runway length. Taxiway lines, on the other hand, belong to the taxiway marking system used to guide movement between ramps and runways, not to the runway marking set. So taxiway lines aren’t part of the seven runway markings.
