What is prohibited regarding LAHSO operations during adverse conditions?

The context of LAHSO (Land and Hold Short Operations) during adverse conditions specifically addresses safety and operational limits that ensure the well-being of passengers and crew, as well as compliance with aviation regulations. Regarding the prohibition of LAHSO operations on wet runways, this is due to the increased risk of runway incursions and decreased braking efficiency that wet surfaces can cause.

When runways are wet, the potential for hydroplaning increases, which can severely affect an aircraft's ability to stop safely within the required distance. This undermines the purpose of LAHSO, where the intention is to hold short of a specified point while ensuring an adequate margin for safety in both landing and maneuvering scenarios. Thus, executing LAHSO under such conditions would conflict with maintaining proper control and safety protocols that are crucial in aviation operations.

The other considerations, while relevant to certain flight operations, do not have the same direct safety implications as the condition of the runway itself. Proper landing distance calculations can still be made even if the runway is wet, night operations are permitted under specific protocols, and headwind limitations vary based on the aircraft's type and operational guidelines.
