This equation shows the connection between the compass course (cc), true course (tc), and its variations (var). To convert a true course into a magnetic compass course (mc) we need first assign a “ – ” to a Western and a “ + ” to an Eastern variation. Note that this makes sense because of the clockwise ↻ direction of the compass course. Data given: magnetic course = mc = 98° true course = tc = 90° variation = 5° W Here, as you confirmed the western variation is 5°, hence −5°. Now, use the same but re-written equation: cc = tc − var cc = 90° – (-5°) cc = 95° Hence, compass course = cc = 95° Now, lets apply the main equation. tc − var = cc + dev = mc now we need to find deviation by converting the formula as below dev = mc – cc dev = 98° – 95° dev = 3° Hence the deviation of the compass is +3° for more details refer the link 2 Reply Share Share Share on Facebook Share on Twitter Share on LinkedIn Share on WhatsApp Leave an answerLeave an answerCancel reply Featured image Select file Browse Add a Video to describe the problem better.
