From the DoD FLIPs or the Tactical Plotting Chart for your area, you can obtain which information?

• A. Local variation
• B. Obtain local magnetic variation
• C. True north direction
• D. Magnetic inclination

Answer: (B)

The information you pull from DoD FLIPs or a Tactical Plotting Chart is the local magnetic variation. This shows how far and in what direction magnetic north differs from true (geographic) north for your area. With that variation, you can convert between true headings and magnetic headings used in plotting and navigation. The rule is simple: Magnetic heading equals true heading plus variation (add if the variation is east, subtract if it’s west). For example, a true course of 045 degrees with east variation of 12 degrees becomes a magnetic course of 057 degrees; if the variation is west 12 degrees, the magnetic course would be 033 degrees. The other options aren’t what these charts provide: true north direction is just the grid’s orientation, and magnetic inclination (dip) is a different magnetic parameter not shown on standard plotting charts.
