Which diamond mileage is 20 miles NW MHZ VORTAC?

• A. V557 SW MHZ JAN APCH
• B. V74 w/ JAN APCH
• C. V74 w/ Sector 67
• D. V245 w/ POE LO

Answer: (B)

Diamond mileages are distance markers shown along federal airways that tell you how far you are from a VORTAC (here, MHZ) in a specific direction along the airway. If a diamond symbol is placed 20 miles in the NW direction from MHZ on an airway, that’s the 20 NM NW MHZ VORTAC mileage point for that airway and segment. In this case, the 20 NM NW MHZ VORTAC mark sits on the V74 airway in the JAN APCH segment. That’s why the correct choice is the V74 w/ JAN APCH option. The other choices point to different airways or different segments (sector, LO, or other approaches), and thus do not correspond to the 20-mile NW mark from MHZ.
