Which navigational error increases when eighteenth-century navigators misalign sextant mirrors on a rolling ship?

💡 Explanation

When sextant mirrors are misaligned while taking celestial altitude measurements, parallax error increases because index error is introduced, creating consistent angular deviations from the object. Therefore, inaccurate altitude results, rather than leeway, dead reckoning, or current drift, which are derived by separate methodologies.
