What are the diamond miles for V557 in PCU LO?

• A. 17 miles NW MHZ
• B. 23 miles NE SQS
• C. 21 miles NW MCB
• D. 18 miles NW MHZ

Answer: (C)

Diamond miles show how far you are along a published V airway segment from a reference point (like a VOR or fix) and the direction from that point. For V557 in the PCU LO area, the marker along the route toward the next fix points you 21 nautical miles in the northwest direction toward the MCB VOR/fix. That specific distance and direction match the charted diamond mile value for this segment, making 21 miles NW toward MCB the correct reading. The other options would indicate different reference points or directions that aren’t on this V557 segment in PCU LO.
