What is the width of a victor airway?

A victor airway is a designated route for aircraft navigating under Instrument Flight Rules (IFR) in the United States, primarily used for navigation at lower altitudes. The width of a victor airway is consistently defined as 4 nautical miles on either side of the centerline, which totals an effective width of 8 nautical miles. This width ensures that aircraft have adequate lateral separation while following the airway, allowing for safe transit through busy airspace.

Since the correct answer reflects this specific measurement, it emphasizes not only the structure of victor airways but also the importance of ensuring safety and navigational precision for aircraft operating within these designated routes. Understanding the dimensions of airways, like victor airways, is crucial for pilots and air traffic controllers to maintain safe distances between aircraft during flight.
