USCG Exam PracticePlotting with variation and deviation (T-V-M-D-C)

A true course of 200° is plotted. Variation is 5°E and deviation is 3°W. What compass course should be steered?

  1. A. 208°
  2. B. 202°
  3. C. 192°
  4. ✓ 198°Correct

Why D is correct

Uncorrecting true to compass: subtract easterly, add westerly. True 200° − 5°E variation = magnetic 195°; magnetic 195° + 3°W deviation = compass 198°. (Bowditch Ch. 6 §602)
