💭 Think About

• Ask yourself: What natural phenomenon makes the direction shown on a magnetic compass different from true north? • Which term applies to errors caused by the ship’s own magnetic fields and metal structure, rather than the Earth itself? • When converting between true and magnetic headings, which named angle do you add or subtract first?

✅ Before You Answer
