Which of the following is required for LAHSO to be accepted?

The requirement for LAHSO (Land and Hold Short Operations) to be accepted is that the landing distance available must be sufficient to accommodate safe operations. Specifically, the available landing distance must be at least the landing distance specified in the Aircraft Flight Manual (AFM) plus an additional 1,000 feet. This added buffer accounts for variations in conditions and ensures that pilots have a safe margin for landing. The AFM typically provides the minimum landing distance required for various conditions, and the additional distance is critical for maintaining safety during LAHSO, which is designed to allow for efficient runway use while ensuring adequate separation between landing and departing aircraft.

This requirement helps to prevent situations where an aircraft might not have enough runway to safely land and hold short of an intersection or other operational point on the runway, thereby enhancing safety in busy airport environments.

In contrast, other options such as restrictions on night operations, specific wind conditions, or recent reports of windshear do not specifically address the necessary landing distance criteria required for LAHSO.
