Which chart would you refer to for military training routes when planning a flight?

When planning a flight that might involve military training routes, the appropriate chart to refer to is the sectional chart. This type of chart provides comprehensive information about airspace structure, navigation aids, and various flight-related considerations, including the location of military training routes (MTRs).

Sectional charts display the routes and their associated altitudes, making it easier for pilots to avoid areas where military operations are occurring, thus ensuring safety while also maintaining situational awareness during the flight. The inclusion of military symbols and references on sectional charts is explicitly designed to inform pilots about these special use airspaces.

Other charts, such as terminal area charts and VFR navigation charts, serve different primary purposes. Terminal area charts focus on procedures around airports and are more detailed in those specific areas, while VFR navigation charts provide broader navigational information and are designed for visual flight rules navigation but do not emphasize military training routes in the same way. Airport diagrams are specifically meant for ground navigation at airports and do not contain information about air routes or airspace designations.
