What are the diamond miles for V74 in D67?

• A. 28 miles SE GLH
• B. 26 miles SE GLH
• C. 26 miles NE GLH
• D. 23 miles SE GLH

Answer: (B)

Diamond miles show how far along a published airway you are from the reference navigation aid to the edge of a designated airspace (like D67). For V74 within D67, the distance to the boundary is measured from the GLH VOR along the airway in the southeast direction. The chart indicates this boundary is 26 miles away to the southeast of GLH, so the correct value is 26 miles SE of GLH. The other options would imply different distances or directions that don’t match the boundary position along that airway segment.
