Which VORTAC is associated with the V9 w/ Sector 15 diamond mileage?

• A. SQS VORTAC
• B. MHZ VORTAC
• C. PHX VORTAC
• D. LAX VORTAC

Answer: (A)

On enroute navigation charts, the mileage diamonds show how far you are along a given airway within a defined sector, and the VORTAC that defines that sector is the reference point for those mileages. When you see V9 tagged with Sector 15 diamond mileage, the mileages in that sector are tied to the VORTAC that defines Sector 15 on that airway. In this chart context, that VORTAC is SQS, so SQS VORTAC is the facility associated with the V9 segment in Sector 15. The other VORTACs listed (MHZ, PHX, LAX) are tied to different sectors or different airway segments, so they don’t carry the Sector 15 diamond mileage on V9.
