You swung ship and compared the magnetic compass against the gyro compass to find deviation. Gyro error is 2°W. The variation is 8°W. Find the deviation on a magnetic compass heading of 022°.

Correct Answer: Option B — 0.0°

Compass error is the algebraic sum of variation and deviation (CE = Var + Dev). Given a gyro error of 2°W and variation of 8°W, total compass error is determined, allowing exact calculation of deviation as 0.0° for the 022° magnetic heading.
