🔍 Key Concepts

• Variation vs Deviation – know the difference and what each one affects • The relationship between compass heading, magnetic heading, and ship’s magnetism • What it means when one of the error terms is zero on a particular heading

💭 Think About

• Start with the basic formula that links true, magnetic, compass, variation, and deviation. What part of that formula compares compass and magnetic? • If the compass and magnetic headings match, what does that tell you about the difference between them? • Ask yourself: Does this situation say anything about nearby metal affecting the compass, or does it say something about the numerical value of deviation on that specific heading?

✅ Before You Answer

• Write out the standard relationship: Compass ± Deviation = Magnetic and see what must be true for compass = magnetic • Check the definitions: Variation is from the Earth’s magnetic field; Deviation is from the vessel’s own magnetism • Make sure you distinguish between no deviation on that heading and no deviation on any heading – those are not the same statement
