🔍 Key Concepts

• Great circles on the Earth and what makes one "primary" • How altitude of a celestial body is measured in celestial navigation • What it means to "reduce" celestial observations to a reference line

💭 Think About

• Look at each statement (A, B, C) and ask: Is this a definition of the equator, or is it describing something related to the equator? • For choice A, think about: From what reference is altitude usually measured in celestial navigation – from the equator or from the horizon? • For choice C, ask yourself: When you plot or reduce celestial observations for position fixing, are you reducing them to the equator, or to another reference like a specific latitude or assumed position?

✅ Before You Answer

• For each choice, decide is this strictly true about the equator itself, or is it mixing in other navigation concepts? • Confirm that you clearly understand the definition of a great circle and how the equator fits that definition. • Before choosing D (All of the above), make sure every single statement (A, B, and C) is fully correct about the equator, not just partially related.
