Touchdown zone can be defined as the first 3,000ft of the runway.
What if the runway is only 3,000 ft? if it is 5,000 ft and I touch down at 2,999 ft down is that ok? Oh, I am doing 125 kts at touchdown....
Runway Touchdown Zone Markers: 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, Precision Instrument Runway Markings. For runways having touchdown zone markings on both ends, those pairs of markings which extend to within 900 feet (270m) of the midpoint between the thresholds are eliminated.
