What is the total width of a federal airway if it is 4 NM on each side of the centerline?

• A. 8 nautical miles
• B. 4 nautical miles
• C. 6 nautical miles
• D. 10 nautical miles

Answer: (A)

Federal airways are shown as a central line with a uniform width around it, typically 8 nautical miles wide in total. That means 4 nautical miles to each side of the centerline. If the airway is 4 NM on each side, you add the left 4 NM and the right 4 NM together, giving a total width of 8 NM. This symmetric width is the standard for IFR navigation within the published federal airways, unless a chart indicates a different dimension for a specific segment.
