Which diamond mileage is associated with the MCB VORTAC?

• A. V9 w/ PCU LO
• B. V18 w/ Sector 65
• C. V74 w/ JAN APCH
• D. V11 w/ Sector 65

Answer: (A)

Diamond mileages are distance markers you see along Victor airways on IFR enroute charts. They show the distance from the VORTAC to a designated fix or point along that airway, and they’re drawn as small diamond symbols with the mileage and the associated fix. For the MCB VORTAC, the diamond mileage tied to it is the one shown on airway V9 to the PCU LO fix. That pairing is what the chart uses to indicate the distance along V9 from MCB to PCU LO, so it’s the correct association. The other options don’t match the published diamond mileage for MCB VORTAC on the chart (they point to different airways or different fixes).
