2026 Military Airspace Procedures Practice Test – Complete Exam Prep

Diamond miles are fixed distance markers shown along a military airway on the chart. They tell you how far along the airway you’ve traveled from a known VOR fix, helping you fix your position and plan with respect to airspace boundaries. For V417 from MHZ to D65, the chart shows a diamond mile at 12 miles in the SE direction from MHZ toward D65. So the correct reading is 12 miles SE of MHZ. The other distances or opposite directions don’t match the marked diamond on that airway segment.
