🔍 Key Concepts

• Adjustable sextant errors vs non-adjustable construction errors • Which part of the sextant affects the image sideways rather than up/down • The role of the horizon glass, index mirror, and telescope alignment

💭 Think About

• Ask yourself: which error would make the direct and reflected horizons appear separated SIDE‑TO‑SIDE when the sextant reads 0°? • Think about which component’s misalignment would shift the line of sight horizontally rather than vertically. • Which of these four options is not normally corrected by the navigator during routine adjustment?

✅ Before You Answer

• Identify which three errors are the standard adjustable errors on a sextant and which one is a permanent/structural error. • Recall that side error is checked by looking at a star and seeing whether the direct and reflected images line up vertically when on the arc and off the arc. • Match the nature of side error (sideways displacement of images) to the part whose tilt or non‑parallelism would cause that effect.
