What phraseology is used for holding an aircraft or vehicle clear of the runway?

The phraseology for holding an aircraft or vehicle clear of the runway is "Hold short of (rwy number; traffic or other info)." This instruction is specific and clear, providing the pilot or vehicle operator with the exact runway they need to hold short of, along with any pertinent information regarding traffic or conditions. This enhances safety by ensuring that all parties are aware of where the holding point is located and any potential hazards.

Using the term "hold short" followed by the runway number is standard because it communicates both the location and the required action, minimizing the risk of confusion or misinterpretation during busy operations. It is especially vital in airport environments where multiple runways and taxiways are in close proximity.

The other options do not provide the same level of specificity. The phrase involving the taxiway does not pertain to runway clearance. "Prepare for landing" is used in a different context related to aircraft descending and landing but does not imply holding clear of a runway. "Clear to taxi" indicates permission to move on ground surfaces but does not imply a holding position relative to a runway, which can lead to misunderstandings in the busy airspace of an airport.
