Land and Hold Short Operations (LAHSO) is a procedure approved for a limited number of airports in Australia only, in which the Tower controller will clear an aircraft to land under the condition that it holds short of an intersecting runway. This procedure allows for the cross runway to be used simultaneously for landing, departing, or crossing traffic, and as a result increases capacity.
LAHSO is NEVER to be used in New Zealand or Papua New Guinea, as local instructions do not permit for this, and must only be used at LAHSO approved airports (see below).
LAHSO Operations are permitted at the following airports only:
LAHSO Operations are approved for runway 34 (holding short runway 09/27) only.
LAHSO Operations are approved for runways 29 (holding short runway 18/36) and 36 (holding short runway 11/29).
Refer to Operations Manuals for further information on specific local rules.
LAHSO may not be used at any airport in the XO region, except for the airports listed above.
When LAHSO is in use, it must be included on the ATIS.
"Runways 29 and 36, land and hold short operations in progress"
When issuing a LAHSO clearance, the pilot accepts responsibility for ensuring they will hold short of the LAHSO holding point. Pilots can reject a LAHSO clearance.
In real life, LAHSO requires a pilot endorsement, therefore ATC will often ask pilots on initial contact if they are LAHSO endorsed. This can be simulated on IVAO to ensure pilots are comfortable with the clearance they are about to receive.
When issuing a LAHSO instruction, it is imperative that the correct phraseology is used to ensure a collision does not occur due to a misinterpretation of the clearance. Traffic information must be given, making the pilot aware of the other aircraft. The landing aircraft must be instructed to hold short of the cross runway prior to being cleared to land. The following phraseology shall be used:
Controller:
Velocity Five Thirty Four a Cessna 441 landing on crossing runway, hold short Runway Two Seven, Runway Three Four cleared to land.
Pilot:
Hold short Runway Two Seven, cleared to land Runway Three Four, Velocity Five Thirty Four
Controller:
Jetstar Six Twenty Two A320 departing on crossing runway, hold short Runway Two Seven, Runway Three Four cleared to land.
Pilot:
Hold short Runway Two Seven, cleared to land Runway Three Four, Velocity Five Thirty Four
The following phraseology shall be used in the takeoff clearance for an aircraft departing a cross runway, when LAHSO is being used on the cross runway:
Controller:
Qantas Thirty Three, Boeing 737 landing on crossing runway will hold short – Runway Two Seven cleared for take-off.
Pilot:
Runway Two Seven, cleared for take-off, Qantas Thirty-Three.
LAHSO should be exercised with caution, several factors should be included considering:
LAHSO must not be used when the cloud is SCT, BKN, OVC AND at or below 2000ft, or when the visibility is at or below 8km.
