Aiming point and touch-down markers are large white rectangles, often referred to as ____________, located roughly ______ from the runway beginning.

• A. Touchdown Zone Markers; 1000 Feet
• B. Aiming Point Markers; 500 Feet
• C. Touchdown Markers; 2000 Feet
• D. Landing Zone Markers; 1500 Feet

Answer: (A)

On precision runways, two large white rectangles placed on either side of the centerline are the aiming point markings. They sit about 1,000 feet from the threshold and provide the pilot with a clear visual target for where to touchdown during an instrument approach. In many references these aiming point markings are described within the broader set of touchdown-related markings, so they’re often referred to as Touchdown Zone Markers. The 1,000-foot distance matches the standard placement for the aiming point markings. The other options either misname these markings or give distances that do not correspond to the aiming point location (for example, the first touchdown zone bars start at 500 feet, not at 1,000).
