How does a departure off a runway used for LAHSO operations work? Let's say that LAHSO operations are in effect at Long Beach (KLGB). Runway 12/30 has a hold short line short of runway 8L / 26R. If an aircraft is cleared to land runway 30, and LAHSO operations are in use, I get that.

But how do operations work for departures off of runways that have a hold short line painted on the runway? If an aircraft is cleared for takeoff runway 30, is the aircraft expected to disregard the hold short line at the departure end of the runway and use full-length?

The LAHSO line and pulsating white light bar applies only to landing traffic (when in effect and when accepted).

A phraseology example is:


  ATC: "(Aircraft ID) cleared to land runway six right, hold short of taxiway bravo for crossing traffic (type aircraft)."


There is no phraseology equivalent to a departing plane that has to do with LAHSO operations. If a runway is shortened for any reason, "shortened" will be added to the taxi and takeoff clearances, but this is another matter.



When a departure is involved as shown above, it is the landing traffic that needs to land and hold short.
