For LAHSO, which describes the distance used to determine allowable touchdown?

When operating LAHSO, the key safety check is whether you can touch down well before the hold-short point, leaving enough distance to decelerate and stop if needed. The distance used to determine if a touchdown is allowable is the first one-third of the Available Landing Distance (ALD) to the hold-short point. In other words, you must be able to touchdown within the initial third of that available distance. This provides a margin to ensure you won’t cross the hold-short line. If the ALD to the hold-short point is 9,000 ft, you would need to be able to land by roughly 3,000 ft from the threshold. The full ALD isn’t used for this determination, and it isn’t the shorter of the first third and a fixed distance. This one-third rule specifically governs whether a LAHSO clearance can be issued.
