Land and hold short operations, or LAHSO, is a tool that allows air traffic control to conduct simultaneous arrivals on intersecting runways. It’s a clearance to land and then stop before the intersecting runway or taxiway. Because LAHSO exists as a means to increase operations on a particular airport, it is typically used at larger and busier airports. Given the rare nature of the procedure and its potential for traffic conflicts, it’s important to know the details of how LAHSO works.
