Refer to Figure 58. To fly a magnetic heading of 120°, what heading should the pilot steer by the magnetic compass?

Choices

✓ 116°correct
The compass correction card reads "For 120, Steer 116" — the deviation correction for that heading.
124°
The card shows Steer 116 for 120; 124 applies the correction in the wrong direction.
120°
The card exists precisely because the compass reads differently from the desired heading; steer 116.
148°
148 is the steer value for a desired heading of 150, not 120.

Why

A magnetic compass correction (deviation) card gives the compass heading to steer for a desired magnetic heading. For a desired 120°, the card in Figure 58 says steer 116°.
