What are the diamond miles for V427 on edge of MLU APCH?

• A. 31 miles NE MLU
• B. 31 miles NW MLU
• C. 30 miles NE MLU
• D. 35 miles NE MLU

Answer: (A)

Diamond miles mark how far along an airway you are from the primary facility to the boundary of the approach area. For V427 at the edge of MLU APCH, that boundary is 31 miles from the MLU VOR in the northeast direction. So the distance shown is 31 miles northeast of MLU. This helps you know when you’re entering the approach airspace and when to coordinate with or switch to approach control.
