70% to pass

When adjusting a magnetic compass for error, a deviation table should be made _______________.

A after adjusting the fore-and-aft and athwartships permanent magnets
B before the quadrantal correctors are placed on the compass
C before correcting for any deviation
D after correcting for variation
AI Explanation

The correct answer is A) after adjusting the fore-and-aft and athwartships permanent magnets. When adjusting a magnetic compass, the first step is to correct for any permanent magnetic deviation by adjusting the fore-and-aft and athwartships permanent magnets. Once this is done, a deviation table should be created to record the compass error at various headings. This deviation table is essential for properly compensating the compass and ensuring accurate navigation. The other options are incorrect because: B) quadrantal correctors are placed on the compass before creating the deviation table, C) the deviation table should be made after the initial permanent magnet adjustments, and D) variation is a separate correction that is applied after the deviation table is created.
