Land and Hold Short Operations (LAHSO) are conducted at airports with intersecting runways or a landing runway and an intersecting taxiway or other hold short point, such as an intersecting runway approach path. If you receive a LAHSO restriction with your landing clearance, accept it only if you've reviewed the landing distance and other information and feel comfortable with the operation.
If LAHSO operations are being conducted and you'll be unable to accept a LAHSO clearance, advise ATC as soon as possible so they can plan for that in the approach and runway you are assigned.
LAHSO information is contained in the Airport/Facility Directory.
