LAHSO touchdown requirement: Where must the touchdown be accomplished?

• A. In the first one-third of the available landing distance or in the first 3,000 ft, whichever is less.
• B. At any point along the runway.
• C. Within the last third of the runway.
• D. Within the first half of the landing distance.

Answer: (A)

The key idea is safety margin for stopping before the hold-short point. When a LAHSO clearance is issued, you must touch down far enough from the threshold so you have enough runway after touchdown to stop before the intersecting runway’s hold-short line. The standard requirement is to touchdown within the first one-third of the available landing distance, or within the first 3,000 feet, whichever is less. This keeps a consistent safety buffer across runways of different lengths, ensuring you can decelerate and stop in time even with typical variations in braking, wind, or performance. Choices that place touchdown later in the runway would leave insufficient distance to stop before the hold-short line and are not permitted. Touching down anywhere else would also defeat the safety intent. The rule is specifically set as the first one-third of the LDA or the first 3,000 feet, whichever is less, to provide that dependable margin. If you can’t meet this requirement, you should not accept the LAHSO clearance.
