What is the width of a victor airway?

The width of a victor airway is established as 4 nautical miles on either side of the centerline of the airway. This standardized width is important for ensuring safe navigation and separation of aircraft traveling along these airways. The design of these airways takes into account the necessary lateral clearance to accommodate variations in navigation accuracy, weather conditions, and other operational considerations. The invocation of a 4 nautical mile width on each side helps provide a buffer zone for pilots to maneuver safely while staying within the designated airway, thus reducing the risk of mid-air collisions and enhancing overall air traffic safety.

The other choices suggest different widths that do not align with the established standards for victor airways, which are specifically defined to be 8 nautical miles in total, making the chosen answer the only correct option in this context.
