Touchdown Zone Marking

The touchdown zone is the first 3,000 feet of the runway or the first third of the runway, whichever is less, measured from the threshold in the direction of landing. The touchdown zone markings identify the touchdown zone for landing operations and are coded to provide distance information in 500 feet (150m) increments. These markings consist of groups of one, two, and three rectangular bars symmetrically arranged in pairs about the runway centerline, as shown below.
