🔍 Key Concepts

• Compass error vs variation vs deviation • Sources of error in a magnetic compass (Earth’s magnetic field vs ship’s magnetism) • What it means when deviation = 0° on a given heading

💭 Think About

• Think about the definition of compass error: what two angles does it compare? • If deviation is zero, what part of the total compass error is left? • Does having no deviation mean the compass will be perfect everywhere on Earth, or only remove one source of error?

✅ Before You Answer

• Be clear that variation is from the Earth’s magnetic field and charted, while deviation is from the ship • Ask: If deviation = 0°, is variation still present? • Check whether compass error can ever be zero just because you adjusted out deviation
