What are the diamond miles for V557 coming out of JAN APCH heading towards MCB?

• A. 33 miles SW MHZ
• B. 25 miles SE MHZ
• C. 33 miles NW MHZ
• D. 40 miles SW MHZ

Answer: (A)

Diamond miles are distance markers along a military airway that you use to gauge position as you fly a leg, from one fix toward the next. On V557, when you’re coming out of JAN APCH toward MCB, you follow the southwest-directed leg of the airway. The chart shows a diamond-mile marker at 33 miles in the southwest direction for that segment, so your current position marker on that leg is 33 miles SW. That’s why the 33 miles SW reading is the correct one. The other options don’t fit because they place you at the wrong distance or the wrong direction along the same leg (for this path, the direction must be southwest).
