Block 1 Military Airspace Procedures (MAP) Practice Test 2026 - Free Military Airspace Procedures Practice Questions and Study Guide

Diamond miles are distance markers on military enroute charts that show how far you are along a given airway from a referenced point or fix. They help you determine your position when flying along the route, especially when navigating by chart references.

For V535 toward HLI, the chart’s diamond-mile notation places a 23-mile point in the NE direction toward SQS. That means, on this segment, the appropriate diamond mile reading is 23 miles in the NE direction toward SQS, which is why that option is the match for the question. The other distances would align with different fixes or different directions along the airway, not this leg toward HLI.
