How are Military Training Routes depicted on charts?

• A. Grey lines labeled IR or VR
• B. Solid blue lines with VOR symbols
• C. Dashed magenta lines with altitude restrictions
• D. Green shaded sectors

Answer: (A)

Military Training Routes are shown on IFR enroute charts as gray lines labeled with IR or VR. The IR designation marks high-altitude instrument routes, while VR marks lower-altitude routes used for visual or training flight. The gray color distinguishes these routes from ordinary airways and other airspace features, signaling pilots to be aware of potential military activity and, if applicable, altitude or time restrictions. The other descriptions don’t represent how MTRs are depicted: standard airways are shown with blue/VOR symbols, other magenta or dashed lines indicate different types of airspace or restrictions, and green shaded areas correspond to different airspace representations, not MTRs.
