What is the correct phraseology for issuing the runway?

Answer: A — Runway One Zero

The correct phraseology for issuing the runway is "Runway One Zero." In aviation communication, particularly with air traffic control, standardized phraseology is crucial for clarity and safety. The term “Runway One Zero” indicates Runway 10, which is the correct way to refer to runways numbered based on their magnetic heading, rounded to the nearest ten degrees. Using "One Zero" follows the conventions set by the International Civil Aviation Organization (ICAO) and helps prevent confusion. For example, "Runway Ten" could lead to misunderstandings with pilots who may not interpret it correctly, as they might not recognize it as a designation for Runway 10. Therefore, sticking to the standard terminology helps maintain clear and effective communication between air traffic controllers and pilots.
