What phraseology is used to expedite a taxiing aircraft?

The phraseology "Action, rwy) without delay (traffic info)" is used to expedite a taxiing aircraft by providing clear and concise directions. This phrase indicates that the aircraft should proceed to the assigned runway promptly, allowing for the efficient management of air traffic and minimizing any potential delays. The inclusion of traffic information also helps the pilot maintain situational awareness as they taxi, ensuring safety while facilitating expedited movement.

Using this specific phraseology helps standardize communication, reduces the chance of misunderstanding, and aligns with air traffic control procedures aimed at keeping operations smooth and timely. It provides both instruction and situational context, which is essential in a busy terminal environment.

Other options may imply urgency but do not carry the same level of clarity or specific action direction as this choice. For instance, "Taxi without delay" is somewhat less specific and doesn't direct the aircraft to a particular runway, which could lead to ambiguity for the pilot. "Clearance granted for immediate departure" might be misinterpreted as ready for takeoff rather than taxiing instructions. Finally, "Proceed to runway as advised" does not necessarily convey the urgency intended to expedite, and could simply mean to continue to the runway at the pilot's discretion.
