Which route has a diamond mile of 23 miles NE SQS?

• A. V557 in PCU LO
• B. V417 from MHZ towards MLU
• C. V18 from MHZ towards MLU
• D. V535 towards HLI

Answer: (D)

A diamond mile is a distance marker along an IFR airway shown on enroute charts, indicating a fixed mileage from a reference navaid such as SQS. To answer, you look for which airway has a diamond symbol with a mileage of 23 miles positioned in the northeast quadrant relative to SQS. The V535 routing toward HLI is the one that passes a diamond mile labeled 23 miles NE of SQS, so it’s the route described by the question. The other airways do not place that 23-mile NE marker along their segments.
