🔍 Key Concepts

• Observed altitude (Ho) vs Computed altitude (Hc) in celestial navigation • What a circle of equal altitude represents on the Earth • How we use the difference between Ho and Hc when plotting a Line of Position (LOP)

💭 Think About

• Ask yourself: in sight reduction, which quantity is expressed in nautical miles and tells you how far your assumed position is from the true position along the azimuth? • Which of these terms relates specifically to the difference between two altitudes turned into a linear distance on the Earth? • Look at each choice and decide: is this an angle, a time correction, or a linear distance used in plotting a position line?

✅ Before You Answer

• Identify which option refers to a linear distance in nautical miles, not an angle or a time correction. • Confirm which term is used together with toward/away along the azimuth to plot the Line of Position. • Eliminate any choices that are purely angular (degrees) or time-based (minutes/seconds of time), not miles.
