If the variation is 3°E, and the deviation is 2°E. Calculate<br />

the compass error?<br />

Solution:<br />

Variation = 3°E<br />

Deviation = 2°E<br />

<strong>Compass</strong> error = ΣVariation + Deviation = 3 +2 = 5°E<br />

•<br />

If the variation is 4°W, and the deviation<br />

is 2°E. Calculate the compass error?<br />

Variation = 4°W<br />

Deviation = 2°E<br />

<strong>Compass</strong> error = -4 + 2 = 2°W<br />
