Which statement best describes the purpose of a taxi via clearance?

• A. Directs the aircraft to taxi on designated routes to or from the runway.
• B. Instructs the aircraft to exit the runway immediately.
• C. Instructs the aircraft to hold short.
• D. Instructs the aircraft to line up and wait.

Answer: (A)

Taxi via clearance is about giving you a precise ground route. It directs you to taxi along specific taxiways to reach the runway or to depart from it, ensuring you follow a defined path rather than wandering about the airport surface. This helps keep ground movement organized and protects runway operations by preventing conflicts and unnecessary backtracking. That’s why this description is the best fit: it emphasizes that the clearance isn’t just “taxi” in general, but a routing instruction that ties your movement to designated taxi routes to or from the runway. In contrast, other actions involve different purposes—exiting the runway immediately is about leaving the runway after landing or an aborted takeoff, holding short means you pause before a runway or taxiway intersection, and line up and wait places you on the runway itself waiting for takeoff clearance.
