🔍 Key Concepts

• Magnetic compass adjustment sequence (what gets corrected first, second, last) • Difference between variation (chart/magnetic difference) and deviation (ship’s magnetism effect) • Purpose and timing of making a deviation table

💭 Think About

• Think about whether a deviation table records existing compass errors, or the residual error after you’ve done all practical corrections • Ask yourself: At what point in the adjustment process do you want a stable, final condition of the compass to be able to chart errors on various headings? • Consider what parts of the ship’s magnetism are corrected by permanent magnets vs. soft-iron/quadrantal correctors

✅ Before You Answer

• Be clear on the difference between variation (from the chart) and deviation (from the vessel) and which one you can change by adjusting the compass • Decide whether it makes sense to build a deviation table while adjustments are still changing the compass, or only after adjustments are completed • Check which options describe actions that are part of compass adjustment (physical correction) versus actions that are part of error documentation (recording remaining error)
