What is the approved phraseology for intersection takeoff?

The approved phraseology for intersection takeoff is designed to provide essential safety information to pilots, ensuring they understand the specifics of their departure point. The correct response, which states, "Runway # at (taxiway) intersection departure (remaining length in ft) available," communicates not only the runway number but also the exact intersection from which the takeoff will occur and the remaining length of the runway. This crucial information enables pilots to assess their takeoff performance accurately, including the impact of available runway length on their aircraft's takeoff distance requirements.

This phraseology is standardized to promote clarity and reduce the risk of misunderstandings between air traffic control and flight crews, which can be critical in busy terminal environments. By providing the remaining length of the runway, the phrase also aids in situational awareness for the pilots, allowing them to make informed decisions regarding their departure.
